What a Tech Pack Is (and Why It Matters)

A tech pack is the master specification a factory uses to cut, sew and finish your garment. A clear pack removes guessing, prevents rework, and is the basis of an accurate quote and a consistent bulk run.

Treat the tech pack as a contract of intent. Every detail you omit becomes a factory assumption — often not the one you wanted.

Core Tech Pack Components

  • Flat sketch (front and back) with callouts.
  • Measurement spec sheet with tolerance.
  • Bill of materials: fabric, weight, trims, labels.
  • Colorways and Pantone or TPX references.
  • Artwork placement for print or embroidery.
  • Construction and stitch notes.
  • Packaging and hangtag instructions.

Tech Pack Checklist

ElementWhy it matters
Measurements with tolerancePrevents fit disputes at bulk.
Fabric weight (GSM)Drives hand-feel and cost.
Color standardStops shade variation between lots.
Artwork file (vector)Required for clean print or embroidery.

Missing any of these four is the most common cause of sample rejection and delay.

Common Tech Pack Mistakes

  • Relying on a photo alone with no measurements.
  • Mixing pixel-based art where vector is required.
  • Specifying a color without a standard reference.
  • Forgetting branded trims and their lead time.
If you do not have a full tech pack yet, send what you have. Our team will help you complete it during sampling — this is normal for emerging brands.
