Short version: A tech pack is the blueprint a factory uses to make your garment — measurements, materials, construction, trims and logo placement. You don't have to create one yourself: a good factory's design team builds it from your sketch, photo or reference, often free.
What is a tech pack?
A tech pack (technical package) is a spec sheet that tells the factory exactly how to make your product. It removes guesswork, so the sample comes back like what's in your head — not a surprise.
What goes in a tech pack
- Technical sketch / flat: front and back line drawing.
- Measurements (POM): points of measure and a size chart (graded across sizes).
- Materials (BOM): fabric composition, GSM, trims, elastic, thread.
- Construction details: seam types, gusset, waistband, stitching.
- Colorways: Pantone references.
- Branding: logo method and placement, labels, hangtags, packaging.
Do you have to make it yourself?
No — and this is the part Reddit threads miss. While professional tech-pack services exist (and cost US$100–300+ per style), a real factory with an in-house design team can build the tech pack for you from a sketch, a photo, or a reference garment. At Yesseam that's part of our free design help.
How to brief a factory without a tech pack
- Send a reference photo or a Pinterest board of the vibe and fit.
- Note your target fabric feel (buttery, compressive, ribbed) and use case.
- List sizes, colors and any must-have features (pockets, V-waist, logo).
- We turn that into a tech pack and a fit sample for your approval.
