Ask any manufacturer what separates a smooth first order from a messy one, and most will give the same answer: the tech pack. It's the document that turns "I have an idea for a hoodie" into a garment a factory can actually cut, sew and repeat. If you're developing an original product, it's the most important file you'll create. Here's what it is, from the factory side.
A tech pack (technical package) is the spec sheet for one garment: flat sketches, measurements, materials, construction details, trims, labels, colourways and artwork. It tells the factory exactly what to make so your sample — and every bulk piece after it — comes out the way you intended.
What a tech pack actually is
A tech pack is a set of technical pages for a single style. It isn't a mood board or a Pinterest reference — it's the engineering document that removes guesswork. When it's clear, the factory quotes accurately, samples faster and produces consistent bulk. When it's missing, both sides fill gaps with assumptions, and that's where cost and delays creep in.
What goes inside a tech pack
Flat sketches
Front, back and detail views of the garment — technical line drawings, not styled photos, showing every seam, pocket and closure.
Measurements (POM)
Points of measure with a size chart: body length, chest, sleeve, hem and more, at your base size, ready to grade.
Bill of materials
Every fabric and component: main fabric GSM and composition, rib, thread, drawcords, zips, buttons and their placements.
Construction & stitching
Seam types, stitch density, topstitching, hems and finishing — how the pieces are actually joined.
Trims & labels
Main label, care and size labels, hangtags, and any packaging — with positions and materials.
Colourways & artwork
Colours (ideally Pantone), print or embroidery artwork, placement, size and technique for each decoration.
Add grading rules across your full size range and any special notes — washes, special finishes, tolerance — and the factory has everything it needs to develop the style without a single "what did you mean here?" email.
Why it matters more than anything else
- Accurate quotes: a clear BOM and construction spec let the factory price the real garment, not an estimate that changes later.
- Fewer sampling rounds: most extra sample rounds come from ambiguity. A good tech pack front-loads the decisions, so you approve in one or two rounds instead of five.
- Consistent bulk: the measurements and construction become the standard every bulk piece is checked against, so unit 500 matches unit 1.
- It protects you: the spec is yours. It's what lets you move a proven style between factories, or scale it, without losing the fit and feel.
Tech pack vs a reference sample
A physical reference — a garment you already own and love — is one of the fastest ways to communicate intent, and a good factory can measure and reverse-engineer it. But a reference alone doesn't capture your changes (a heavier fabric, a boxier fit, your trims). The strongest brief is usually both: a reference sample plus a tech pack that spells out what to keep and what to change.
Do you need one before you start?
Not necessarily. Plenty of brands come to us with a sketch, a reference garment and a clear idea rather than a finished tech pack — and that's fine. Part of OEM development is building the tech pack with you: we turn your references and specs into a proper technical package, confirm it through the PP sample approval process, and lock it before bulk. What matters isn't that you arrive with a perfect document — it's that a real spec exists before production starts.
Turn your idea into a spec
Whether you have a full tech pack or just a sketch and a reference, we develop it into a production-ready garment and confirm it on a sample before bulk. See our custom clothing manufacturer page, or our OEM/ODM clothing manufacturer page to develop an original product from your design.
Tech pack FAQ
Do I need a tech pack to get a quote?
It helps a lot — a clear spec lets us quote the real garment instead of an estimate. But you can start with a sketch and a reference sample, and we'll build the tech pack with you during development.
Can you make a tech pack for me?
Yes. Part of OEM development is turning your references, sketches and measurements into a proper technical package, then confirming it on a physical sample before bulk.
What's the difference between a tech pack and a sample?
A tech pack is the written spec; a sample is the physical proof of it. We use the tech pack to make the sample, then use the approved sample as the standard for bulk.
What if I only have a reference garment?
That works. We measure and reverse-engineer the reference, note your changes (fabric, fit, trims), and document it into a tech pack before production.
What's the MOQ once my tech pack is ready?
MOQ starts from 50 pcs per style, with colour and size splits available on most programs.
