A sportswear tech pack is one of the most important documents a brand can prepare before starting custom manufacturing. It turns a design idea into clear production instructions. Without it, a factory has to guess too many details: fabric weight, stitch type, logo size, seam placement, sizing, trims, packaging, and finishing standards.
That guesswork becomes expensive when the first sample comes back with the wrong fit, wrong fabric, poor logo placement, or unclear construction. For sportswear, the risk is even higher because the garment must stretch, move, breathe, recover, and survive repeated washing. A normal fashion sketch is not enough.
A strong sportswear tech pack helps the manufacturer understand exactly what needs to be made. It gives the pattern team, sample team, stitching department, printing team, quality-control team, and packaging team the same production standard.
For brands working with an OEM sportswear manufacturer, a complete tech pack can reduce sampling confusion, improve quotation accuracy, and make bulk production more consistent.
What Is a Sportswear Tech Pack?
A sportswear tech pack is a detailed technical document that explains how a sportswear product should be developed, sampled, manufactured, checked, packed, and shipped. It is also called a technical package, apparel tech pack, clothing tech pack, or product specification sheet.
In simple words, it is the blueprint of the garment.
A basic sketch may show what the product looks like, but a sportswear tech pack explains how it should be made. It covers the measurements, fabrics, trims, stitching, print methods, logo placements, labels, size range, packaging, tolerances, testing requirements, and revision history.
A tech pack is especially important for custom sportswear manufacturing because performance apparel is not only about style. A custom team jersey, compression shirt, sports bra, tracksuit, workout legging, or sports glove must meet practical performance expectations.
A reliable custom apparel manufacturer uses the tech pack as a reference during sampling, costing, production planning, quality inspection, and final shipment.
“A sportswear tech pack is not just a design file. It is the manufacturing language between your brand and your factory.” — BUSHI Sports®
Why a Sportswear Tech Pack Matters in Custom Manufacturing
A sportswear tech pack saves time because the manufacturer does not need to keep asking for missing details. It saves money because fewer sample rounds are needed. It also protects the buyer because every approved production detail is written down.
In custom manufacturing, small mistakes can become large production problems. A logo placed 2 cm too low may look acceptable on one sample but wrong across 500 jerseys. A waistband tolerance that is not defined may create sizing complaints. A fabric described only as “stretchy polyester” may result in a completely different hand feel, GSM, opacity, or recovery.
This is why professional sportswear brands treat the tech pack as a control document, not a formality.
A good sportswear tech pack helps with:
- Accurate sampling
- Better price quotations
- Clear fabric sourcing
- Correct stitching and construction
- Consistent sizing and grading
- Better logo and artwork placement
- Fewer production revisions
- Stronger quality control
- Easier repeat orders
- Clearer communication with the factory
Techpacker describes a tech pack as a blueprint containing detailed flat sketches, materials, measurement specs, grading, and colorways. Surefront also identifies drawings, measurements, materials, markups, comments, BOM, and product attributes as key elements of a complete fashion tech pack. These ideas are highly relevant for sportswear manufacturing because performance garments require even more technical clarity than basic casualwear.
Sportswear Tech Pack vs Basic Design Brief
Many new brands confuse a design brief with a tech pack. A design brief explains the idea. A sportswear tech pack explains the production standard.
| Feature | Basic design brief | Sportswear tech pack |
|---|---|---|
| Main purpose | Explain the concept | Explain how to manufacture the product |
| Sketches | Usually simple | Technical front, back, side and detail views |
| Measurements | Often missing | Full spec sheet with tolerances |
| Fabric details | General fabric name | Composition, GSM, stretch, finish and performance |
| Stitching | Rarely detailed | Stitch type, seam type, SPI and reinforcement |
| Branding | Basic logo idea | Exact placement, size, method and color reference |
| Packaging | Usually not included | Folding, poly bag, labels, tags and carton details |
| Production use | Limited | Used for sampling, costing, QC and bulk production |
A design brief can start the conversation, but a sportswear tech pack is what moves the product toward accurate sampling and bulk manufacturing.
12 Essential Sections of a Sportswear Tech Pack
A complete sportswear tech pack does not need to look complicated, but it must be clear. The best tech packs are easy for a production team to read, follow, and update.
1. Cover Page and Product Overview
The cover page gives the factory a quick understanding of the product. It should identify the style before anyone studies the technical pages.
Include:
- Brand name
- Product name
- Style number
- Season or collection
- Product category
- Gender or target user
- Size range
- Sample stage
- Date
- Revision number
- Main contact person
For example, a cover page may say: “Men’s Sublimated Football Jersey, Style BS-FJ-001, Spring Collection, Sizes S–3XL, Revision 02.”
This simple information prevents confusion when a brand is developing several products at the same time.
2. Technical Flat Sketches
Technical flat sketches show the garment clearly from the front, back, and sometimes side or inside views. These are not fashion illustrations. They should be clean, proportionate, and easy to understand.
For sportswear, flat sketches should show seam lines, panels, vents, pockets, collars, cuffs, waistbands, hems, drawcords, zippers, bindings, mesh panels, contrast fabric areas, and logo positions.
If you are creating a custom sports jersey, the flat sketch should show the neckline, sleeve shape, side panels, back name position, number placement, sponsor logo areas, and hem finish.
If you are creating custom activewear such as leggings, the sketch should show the waistband height, inseam, crotch gusset, side pockets, compression panels, and leg opening.
A clear sketch reduces verbal explanation and makes the sportswear tech pack more useful for the pattern maker and sample team.
3. Bill of Materials
The bill of materials, usually called BOM, lists every material and component used in the product. This is one of the most important parts of a sportswear tech pack because sportswear performance depends heavily on fabric and trims.
A BOM should include:
- Main fabric
- Contrast fabric
- Mesh panels
- Rib fabric
- Elastic
- Drawcord
- Zippers
- Buttons or snaps
- Labels
- Heat-transfer labels
- Woven patches
- Silicone badges
- Hook-and-loop tape
- Padding or foam
- Packaging material
Each item should include composition, color, GSM or weight, supplier reference if available, placement, and approved substitute instructions.
For example, writing “polyester fabric” is too vague. A stronger instruction would be: “100% polyester interlock, 150–160 GSM, moisture-wicking finish, white base for sublimation, approved hand feel sample attached.”
This level of detail helps the activewear manufacturer source the right fabric instead of choosing something that only looks similar.
4. Fabric and Performance Requirements
Sportswear fabric should be described with performance in mind. A sportswear tech pack should not only list composition. It should also explain how the fabric should behave.
Important fabric details include:
- Fiber composition
- GSM or fabric weight
- Stretch direction
- Stretch percentage
- Recovery requirement
- Opacity
- Breathability
- Moisture-wicking requirement
- Hand feel
- Surface texture
- Shrinkage tolerance
- Colorfastness expectation
- Printing suitability
- Washing instruction
For compression garments, stretch and recovery are critical. For teamwear, color brightness and print compatibility may matter more. For gloves, grip material and abrasion resistance become important. For outerwear, lining, insulation, and weather resistance may need extra attention.
A clear fabric page helps prevent one of the most common manufacturing problems: a sample that looks correct but feels wrong.
5. Measurement Spec Sheet
The measurement spec sheet defines the size and fit of the garment. It should include all key points of measurement, often called POMs.
For a sportswear tech pack, common POMs may include:
- Chest width
- Body length
- Shoulder width
- Sleeve length
- Neck opening
- Armhole
- Waist width
- Hip width
- Inseam
- Outseam
- Thigh width
- Knee width
- Leg opening
- Waistband height
- Hem width
Each measurement should include a tolerance. A tolerance is the allowed difference between the target measurement and the actual finished garment.
For example, if the chest width is 52 cm with a tolerance of ±1 cm, a finished garment between 51 cm and 53 cm may be acceptable.
Without tolerances, quality control becomes subjective. With tolerances, both buyer and manufacturer can check the garment fairly.
The BUSHI Sports® sportswear sample approval checklist explains why measurements, fit, tolerances, and written approval comments should be checked before cutting bulk fabric.
6. Size Grading Rules
A sportswear tech pack should show how measurements change from one size to the next. This is called grading.
Grading is especially important for custom teamwear, private label sportswear, and bulk sportswear supplier orders because one mistake can affect the full size range.
A size medium sample may fit well, but the XL may become too short or the small may become too tight if grading is not controlled.
For team uniforms, the size range may include youth and adult sizes. For leggings, grading must protect stretch and recovery. For gloves, grading affects finger length, palm width, wrist opening, and closure position.
When working with a sports uniform manufacturer, brands should confirm the size chart, fit type, tolerance, and grading rules before approving bulk production.
7. Stitching and Seam Construction
Stitching instructions are essential in a sportswear tech pack because seams affect durability, comfort, and movement.
A strong tech pack should define:
- Stitch type
- Seam type
- Stitches per inch
- Thread type
- Thread color
- Seam allowance
- Overlock or coverstitch details
- Flatlock placement
- Bartack placement
- Reinforcement points
- Binding width
- Elastic attachment method
For example, a compression shirt may require flatlock seams in high-contact areas. A tracksuit may use lockstitching, safety stitching, and bartacks. A team jersey may use overlock panel assembly with coverstitched hems.
The BUSHI Sports® article on sportswear stitching types explains how lockstitch, chainstitch, overlock, coverstitch, flatlock, zigzag, bartack, and multi-needle stitching affect sportswear performance.
8. Artwork, Logo, and Branding Details
Branding mistakes are common when the sportswear tech pack does not define artwork clearly. A logo that looks good in a mockup may print too large, sit in the wrong position, or clash with a seam once the garment is assembled.
The artwork page should include:
- Logo file format
- Logo size
- Exact placement
- Color reference
- Print method
- Embroidery method
- Patch or badge details
- Sponsor logo positions
- Name and number placement
- Heat-transfer label position
- Care label position
- Neck label or private-label branding
For sublimated teamwear, artwork must align with the cutting pattern. For embroidery, the fabric must support stitch density. For heat transfer, temperature and pressure compatibility should be considered.
BUSHI Sports® has published useful comparison guides such as direct embroidery versus embroidered patches and silicone badges versus woven patches, which can help brands choose the right branding method for sportswear.
9. Color Standards
Color must be controlled carefully in custom sportswear manufacturing. A shade may look different on a phone screen, laptop, printed paper, and fabric.
A sportswear tech pack should include a physical or recognized color standard wherever possible.
Useful color references include:
- Pantone code
- Fabric swatch
- Printed strike-off
- Sublimation test panel
- Thread color card
- Trim color reference
- Approved sample image
- Contrast color placement
For sports uniforms, color consistency matters because teams expect all garments in the order to match. For retail brands, inconsistent shade can make a product line look unprofessional.
The best practice is to approve physical fabric and print references before bulk production.
10. Labels, Tags, and Packaging
A sportswear tech pack should include private-label and packaging details, especially for B2B brands, retailers, distributors, and e-commerce sellers.
Include:
- Neck label
- Size label
- Care label
- Country-of-origin label
- Composition label
- Hang tag
- Barcode or SKU sticker
- Poly bag
- Folding method
- Carton assortment
- Carton markings
- Retail packaging instructions
BUSHI Sports® offers OEM and private-label manufacturing services including labels, tags, custom packaging, export-ready packing, and worldwide shipping support.
Packaging may look like a small detail, but it affects retail presentation, warehouse handling, distribution accuracy, and customer experience.
11. Testing and Quality Control Requirements
Quality control should be written into the sportswear tech pack before production begins.
Testing and inspection details may include:
- Measurement check
- Stitching inspection
- Print or embroidery check
- Wash test
- Shrinkage check
- Colorfastness check
- Stretch and recovery check
- Seam strength check
- Pilling or abrasion review
- Label accuracy
- Packaging inspection
- Final pre-shipment inspection
For formal seam-strength testing, ASTM D1683/D1683M is a recognized method for testing sewn-seam failure strength in woven apparel fabrics.
Sportswear does not always require laboratory testing for every product, but the tech pack should define what must be checked before approval. BUSHI Sports® lists quality-control steps such as fabric check, cutting check, stitching inspection, measurement check, print/embroidery check, finishing check, packing inspection, and final pre-shipment check.
12. Revision History and Final Approval
A sportswear tech pack should record changes. Every sample round may create updates to fabric, measurements, logo placement, stitching, or packaging.
A revision history page should include:
- Revision number
- Date
- Person responsible
- Change made
- Reason for change
- Approval status
This avoids the common problem of different teams working from different files. A manufacturer may follow Revision 01 while the buyer expects Revision 03. That mistake can damage the sample process and delay bulk production.
Final approval should clearly state which sample, tech pack version, fabric swatch, artwork file, and packaging instruction are approved for production.
Sportswear Tech Pack Example Structure
| Page | Section | Purpose |
| 1 | Cover page | Identify product, style number and revision |
| 2 | Technical sketches | Show garment shape, panels and construction |
| 3 | BOM | List all fabrics, trims, labels and components |
| 4 | Fabric specs | Define GSM, composition and performance needs |
| 5 | Measurement chart | Control fit and production sizing |
| 6 | Grading | Show size-to-size measurement changes |
| 7 | Stitching | Define seams, thread, SPI and reinforcement |
| 8 | Artwork | Control logo, print and embroidery placement |
| 9 | Color standards | Define approved shades and references |
| 10 | Packaging | Control labels, tags, bags and cartons |
| 11 | QC and testing | Define inspection and approval standards |
| 12 | Revision history | Track changes and final approval |
This structure is flexible. A simple gym T-shirt may need fewer pages, while a full private-label sportswear collection may require a more detailed file for each product.
Common Mistakes in Sportswear Tech Packs
A weak sportswear tech pack usually fails because it leaves too many decisions open.
Common mistakes include:
- Using only lifestyle images instead of technical sketches
- Writing “polyester” without GSM, stretch, or finish
- Missing measurement tolerances
- Not defining stitch types
- Providing low-resolution logo files
- Forgetting label and packaging details
- Not confirming color standards
- Ignoring shrinkage and wash testing
- Missing sample revision history
- Approving changes through chat without updating the tech pack
These issues can lead to wrong samples, delayed production, unclear pricing, inconsistent bulk orders, and disputes between buyer and manufacturer.
How a Sportswear Tech Pack Helps With Pricing
Manufacturers cannot quote accurately when product details are missing. A sportswear tech pack gives the factory enough information to calculate fabric consumption, trim cost, printing or embroidery cost, stitching time, packaging, labor, wastage, and production complexity.
A basic T-shirt, sublimated jersey, compression tight, sports bra, tracksuit, and goalkeeper glove all require different costing methods.
A detailed tech pack helps the manufacturer answer important costing questions:
- How much fabric is required?
- Is the fabric easy to source?
- Is the stitching simple or complex?
- Does the product require sublimation, embroidery, heat transfer, or patches?
- Are there custom labels and packaging?
- How many sample rounds may be needed?
- What quality checks are required?
- Is the order small batch or bulk production?
This is why an experienced bulk sportswear supplier will ask for a tech pack, sample, reference image, or detailed requirement before giving a reliable price.
Product-Specific Tech Pack Notes
Sports uniforms
A sports uniform tech pack should focus on fabric breathability, sublimation layout, name and number placement, team crest, sponsor logos, neckline shape, sleeve length, short length, and full size range.
Activewear
An activewear tech pack should define stretch, recovery, opacity, seam comfort, waistband construction, compression level, fabric GSM, and sweat-management expectations.
Sports bras
A sports bra tech pack should include support level, underband elastic, strap construction, lining, removable pad details, coverstitching, binding, and stretch testing.
Tracksuits
A tracksuit tech pack should define jacket and trouser measurements, zipper quality, rib or cuff construction, pockets, lining, drawcords, panel seams, and topstitching.
Sports gloves
A glove tech pack should include palm material, grip zones, padding, finger panels, thumb construction, wrist closure, stitching reinforcement, and logo placement. This is especially important for a custom sports gloves manufacturer because gloves involve smaller curved components and concentrated stress points.
Sportswear Tech Pack Checklist
Before sending a sportswear tech pack to a manufacturer, check that it includes:
- Product name and style number
- Front and back technical sketches
- Fabric composition and GSM
- Stretch and recovery requirement
- Full measurement chart
- Size grading
- Stitching and seam details
- Artwork placement
- Branding method
- Label and tag instructions
- Packaging details
- Color references
- Testing requirements
- Quality-control standards
- Revision history
- Final approval notes
If one of these sections is missing, the manufacturer may still produce a sample, but the risk of misunderstanding becomes higher.

Frequently Asked Questions
What is a sportswear tech pack?
A sportswear tech pack is a technical document that explains how a sportswear product should be made. It includes sketches, measurements, fabrics, trims, stitching, branding, colors, labels, packaging, testing, and revision history.
Do I need a tech pack for custom sportswear manufacturing?
Yes, a tech pack is strongly recommended. It helps the manufacturer create accurate samples, quote correctly, reduce revisions, and keep bulk production consistent.
Can I start with only reference pictures?
Yes, reference pictures can help start the discussion, but they are not enough for accurate custom manufacturing. The manufacturer will still need measurements, fabric details, logo placement, stitching instructions, and sample approval.
What should be included in a sportswear tech pack?
A complete sportswear tech pack should include technical sketches, BOM, fabric specs, measurement chart, grading, stitching details, artwork, color standards, labels, packaging, testing requirements, QC instructions, and revision history.
Who creates the tech pack?
Usually, the brand, designer, product developer, or technical designer creates the tech pack. A manufacturer can also help review and improve it before sampling.
Can BUSHI Sports® manufacture without a tech pack?
BUSHI Sports® can review reference images, physical samples, sketches, and requirements, but a clear sportswear tech pack gives the best result. It reduces confusion and makes sampling more accurate.
Why does a tech pack reduce sample revisions?
A tech pack reduces revisions because the factory receives clear instructions from the beginning. Fabric, measurements, stitching, branding, and packaging are defined before the sample is made.
Is one tech pack enough for a full collection?
Each product should have its own tech pack. A T-shirt, hoodie, legging, tracksuit, glove, and sports bra have different measurements, fabrics, stitching, trims, and testing needs.
Conclusion
A sportswear tech pack is the foundation of successful custom manufacturing. It protects the brand’s design, guides the manufacturer, improves quotation accuracy, reduces sample errors, and creates a clear production standard for bulk orders.
For sportswear, this document is even more important because the product must perform under movement, stretch, sweat, washing, and repeated use. Fabric, stitching, measurements, branding, labels, and packaging all need to be clearly defined before production begins.
BUSHI Sports® helps brands turn ideas, sketches, samples, and tech packs into custom sportswear, private label sportswear, custom teamwear, activewear, sports uniforms, sports gloves, casual wear, outerwear, and equestrian gear.
