In streetwear, a strong concept alone isn’t enough. You can have the best graphics, silhouettes, and ideas, but if your tech pack isn’t clear, the final garment will rarely match what you had in mind. Factories don’t interpret designs creatively or fill in missing details. They work from instructions.
A well-prepared tech pack bridges the gap between creativity and production. It removes ambiguity, reduces sampling rounds, and ensures manufacturers can produce your garment accurately and consistently.
Below is a practical guide to creating a streetwear tech pack that factories can genuinely work from — and the common mistakes to avoid.
What Is a Tech Pack (and Why It Matters)?
A tech pack is a detailed technical document that tells a factory exactly how to make your garment. It includes technical drawings, measurements, materials, construction instructions, and finishing details.
For streetwear brands especially — where oversized fits, heavyweight fabrics, and custom trims are common — clarity is critical. The more precise your tech pack is, the fewer questions a factory will have and the closer your first sample will be to what you envisioned.
What to Include in a Streetwear Tech Pack
1. Clear Technical Drawings (Flats)
Factories rely on technical drawings, not fashion illustrations or mood boards. Your drawings should be clean, black-and-white, and easy to understand.
They should clearly show:
- Front and back views
- Stitch lines, panels, and seam placements
- Close-ups of key details such as pockets, hoods, cuffs, prints, or embroidery
If a detail isn’t clearly drawn, it can’t be produced correctly.
2. Accurate Measurements
Measurements must be specific and consistent. Descriptive terms like “oversized” or “boxy” describe style, not size.
Your tech pack should include:
- All key measurements that differ from the fit reference provided
- Clear measurement points
- Any specific trim measurements
Even oversized garments still need defined dimensions.
3. Fabric and Material Details
Never assume a factory understands vague terms such as “heavyweight” or “premium.” These must be defined clearly.
Your tech pack should specify:
- Fabric type (for example, 100% cotton French Terry)
- Fabric weight (GSM)
- Fabric finish (terry, brushed, enzyme washed, garment dyed, etc.)
For trims, include details for:
- Rib quality
- Zips (brand, size, colour)
- Drawcords, eyelets, and labels
4. Construction and Stitching Instructions
Streetwear garments may look simple, but construction plays a major role in durability and quality.
Your tech pack should clearly outline:
- Stitch types (lockstitch, overlock, coverstitch)
- Seam finishes
- Reinforcements such as bar tacks or twin-needle stitching
If durability is important which it usually is this should be clearly stated.
5. Print, Embroidery & Branding Placement
This is one of the most common weak points in streetwear tech packs.
Always specify:
- Artwork size (in mm or cm – not inches!)
- Placement measured from fixed reference points (for example, “5cm down from centre front neckline”)
- Print or branding method (screen print, puff print, embroidery, heat transfer etc)
- Colour references using Pantone codes
Avoid relying on instructions like “central” or “same as sample” without measurements.
6. Colourways and Size Range
Each colourway should have its own tech pack and individual item or SKU code. Including multiple colourways on a single page often leads to mistakes during sampling and bulk production.
Your tech pack should clearly show:
- Each colour option with Pantone references or fabric swatch codes
- The full-size range to be produced
This clarity helps avoid mix-ups with fabrics, trims, and branding.
What NOT to Do in a Streetwear Tech Pack
Creating a tech pack isn’t about adding more pages — it’s about avoiding the mistakes that cause confusion at the factory level.
Avoid vague or subjective language.
Terms such as “relaxed fit,” “premium feel,” or “slightly longer” are open to interpretation. If something can’t be measured or clearly shown, a factory can’t follow it accurately.
Don’t rely on reference photos alone.
Photos can help explain an idea, but they should never replace clear technical drawings and written instructions.
Don’t leave decisions open-ended.
Instructions like “factory to advise” or “use best method” can result in outcomes you didn’t expect. If something matters to you, it needs to be specified. If you’re unsure, it’s better to ask questions or discuss options rather than leave it undefined.
Don’t overload or disorganise the document.
A tech pack should be easy to follow. One page with a coloured sketch, a few measurements, and scattered notes does not count as a tech pack. Clear layouts, logical sections, and consistent formatting are essential.
Don’t forget to update the tech pack.
If changes are made after sampling, the tech pack must be updated and versioned correctly. Old or conflicting information is one of the most common causes of errors during bulk production.
Final Tips for Streetwear Brands
· Think like a manufacturer, not just a designer
· Assume the factory has never seen your brand before
· Be clear, precise, and repetitive where necessary
· If something matters to you, include it in the tech pack
A factory that follows your tech pack exactly isn’t being difficult — they’re doing their job. The quality of your instructions directly affects the quality of the final garment.
