Tech Packs: What They Are and Why Your Manufacturer Needs Them
If you're launching a clothing brand or preparing your first production run, you’ve likely heard the term tech pack. For many new brands, tech packs feel intimidating—yet they are one of the most essential tools in apparel manufacturing. In fact, most production problems such as incorrect sizing, color inconsistencies, wrong placements, or inaccurate stitching happen because the brand did not provide a proper tech pack.
Whether you are working with clothing manufacturers, developing custom streetwear, producing hoodies with a hoodie manufacturer Pakistan, or planning a performance range with sportswear manufacturers in Pakistan or activewear clothing manufacturers, a tech pack ensures that every detail of your design is translated accurately into a physical product.
This guide breaks down what tech packs are, why they matter, and how they help streamline the manufacturing process for brands of all sizes.
What Is a Tech Pack?
A tech pack (short for technical package) is a detailed manufacturing blueprint for your garment. It includes all the specifications a factory needs to create your item exactly the way you envision it. Think of it as the instruction manual that communicates your design clearly, professionally, and without confusion.
A complete tech pack typically includes:
Technical drawings or flat sketches
Fabric type, GSM, and material specifications
Colorways and Pantone codes
Measurement charts and grading rules
Stitching types and construction details
Artwork placements and printing methods
Label, tag, and packaging instructions
Special features or trims
Any additional notes needed for production
Without a tech pack, a manufacturer must guess certain details—and this is where problems begin.
Why Tech Packs Matter in Apparel Manufacturing
A tech pack is essential because it removes guesswork from the production process. While skilled clothing manufacturers have experience working with different types of garments, they still need clear instructions to ensure consistent results.

Here are the biggest benefits of using a professional tech pack:
1. Eliminates Miscommunication
Miscommunication is the number one cause of production issues. When a designer says “oversized hoodie,” they might envision something different from what a factory interprets.
A detailed tech pack ensures:
Exact measurements instead of general descriptions
Accurate artwork placement instead of verbal instructions
Consistent stitching standards rather than assumed ones
Whether you’re working with a hoodie manufacturer Pakistan or building a complete apparel line, a tech pack ensures everyone is on the same page.
2. Ensures Accurate Samples
Your first sample is your chance to see the actual garment before it goes into bulk production. But a poor or incomplete tech pack leads to incorrect samples that require multiple revisions.
With a detailed tech pack, the sample:
Matches your original design
Reflects correct sizing and fit
Follows exact construction techniques
Uses the intended fabrics and colors
This saves time, reduces revisions, and helps brands move to bulk production faster.
3. Prevents Costly Production Errors
Production mistakes can be expensive. If your teamwear, streetwear, or activewear line is produced incorrectly, the entire batch may need to be remade. This means more time, more fabric, more shipping costs, and lost revenue.
Brands that supply complete tech packs help sportswear manufacturers in Pakistan and other factories avoid errors such as:
Misaligned logos
Wrong panel measurements
Incorrect fabric selection
Inconsistent sizing
Faulty stitching
Clear instructions help manufacturers deliver precise results every time.
4. Helps Calculate Exact Production Costs
Factories provide accurate quotes when they understand every element of the garment.
A full tech pack helps them estimate:
Fabric usage
Labor time
Trims and accessories
Printing or embroidery work
Complexity of pattern making
This allows you to calculate your retail price properly and avoid last-minute cost increases.
5. Maintains Consistency Across Future Orders
As your brand grows, you will place repeated orders or produce new colorways using the same design. Without a tech pack, consistency becomes difficult to maintain.
A complete tech pack ensures that every future batch matches the original production run in:
Fit
Fabric
Color
Stitching
Design features
This is especially important for brands relying on activewear clothing manufacturers, where precision and performance standards must remain consistent.
Key Elements Every Tech Pack Should Include
Whether you are creating custom streetwear or producing premium sportswear, your tech pack needs the following critical components:
1. Technical Drawings (Flats)
These are simple front, back, and side illustrations of your garment. They should be clean, detailed, and easy for clothing manufacturers to understand. Flats eliminate confusion about seams, panels, pockets, and construction.
2. Measurement Sheet
This includes:
Body measurements
Garment measurements
Grading between sizes (S, M, L, XL, etc.)
For oversized streetwear or fitted activewear, accurate measurements ensure your brand maintains a signature fit.
3. Fabric and Material Details
Specify:
Fabric type (cotton, fleece, mesh, polyester blends, etc.)
GSM (weight)
Stretch percentage
Lining materials
Ribbing details
A hoodie manufacturer Pakistan or sportswear specialist needs these details to source or recommend the right fabrics.
4. Colors and Pantone Codes
Color accuracy matters, especially if you plan multiple colorways. Pantone codes prevent mismatched dye lots in future production.
5. Stitching and Construction Details
Add instructions for:
Stitch type (flatlock, overlock, top stitch)
Seam placements
Reinforcement areas
Panel construction
This is crucial for performance gear produced by sportswear manufacturers in Pakistan and activewear clothing manufacturers.
6. Artwork Placement and Printing Specs
Include:
Logo size and placement
Printing methods (screen print, DTG, sublimation)
Embroidery details
Patch placements
The more precise you are, the better your sample will match your vision.
7. Trims, Labels, and Packaging
State requirements for:
Neck labels
Wash-care labels
Hang tags
Drawcords, zippers, and buttons
Packaging style (polybag, branded tags, etc.)
These small details impact your final product’s presentation and branding.
How Tech Packs Help Manufacturers Work More Efficiently
For factories—whether they produce custom streetwear, performance kits, hoodies, or activewear—a tech pack acts as a universal guide. It simplifies communication between design, pattern making, cutting, stitching, printing, and finishing teams.
Manufacturing becomes faster and smoother because:
Every team member works from the same document
No assumptions are made
Quality control is easier
Sample development is faster
Bulk orders stay consistent
When you provide a complete tech pack, you become a preferred client because you make the manufacturer’s job easier—and manufacturers naturally prioritize such brands.

Why New Brands Often Fail Without a Tech Pack
Many beginners skip tech packs to save time or money, but this almost always leads to problems:
Wrong sizing
Incorrect materials
Delayed production
Extra charges for revisions
Misplaced prints and logos
Inability to scale designs
Even the best clothing manufacturers cannot produce your vision accurately without clear technical documentation.
Investing in a tech pack saves far more money than skipping one
