What is a tech pack?

A tech pack (technical package) is the document that tells a factory exactly how to build your garment. Without it, suppliers guess — and guessing drives wrong samples, extra revision rounds, and launch delays.

What factories expect in a tech pack

Most cut-and-sew manufacturers will not quote accurately from a mood board or logo mockup alone. They need structured specs they can pattern and sample from.

  • Technical flat sketches (front and back)
  • Bill of materials (BOM) — fabric, trims, thread, labels
  • Points of measure (POM) with tolerances
  • Size grading rules from your base size
  • Construction details — seam type, stitch class, SPI
  • Artwork or print placement coordinates
  • Colorway references (Pantone or approved swatches)

Who needs a tech pack first

First-time DTC founders, streetwear labels, and kids brands sampling hoodies, tees, or matching sets in the USA or UK hit this wall fastest: the factory replies asking for “full specs” before they will cut a proto.

SendToSample turns one product photo into the first draft of those sheets so you can review and send a factory link — without rebuilding everything in Illustrator.

Related questions

Is a tech pack the same as a tech sketch?
No. A tech sketch is usually one flat drawing. A tech pack is the full package — flats, BOM, measurements, construction, and revision control — that a factory uses to sample and quote.
Do UK and US factories both require tech packs?
Reputable cut-and-sew shops in both markets expect clear specs before sampling. The format is similar; what's missing matters more than the country.
