What Is a Tech Pack? Why It Matters When Choosing a Clothing Manufacturer
If you’ve ever ordered a sample from a clothing manufacturer and gotten back something that didn’t quite match what you asked for β wrong seam finish, a pocket in the wrong place, sizing that’s off β the root cause is usually the same: nobody wrote the spec down properly before cutting fabric. That document is called a tech pack, and whether a manufacturer actually uses one is one of the fastest ways to tell if they can produce to your exact vision.
What Is a Tech Pack?
A tech pack (technical package) is the instruction manual for a garment. It’s the document a brand or designer hands to a factory so that pattern makers, cutters, sewing operators and quality control all build the exact same thing β not their own interpretation of a mood board or a WhatsApp photo. A proper tech pack turns “make it look something like this” into “here is precisely what to cut, stitch and check at every size.”
What’s Inside a Proper Tech Pack
| Section | What it covers |
|---|---|
| Design flats & callouts | Front and back line drawings with every construction detail numbered β collar type, stitch lines, pocket placement, trims |
| Measurement diagram | A labelled flat sketch showing exactly where each measurement is taken on the garment |
| Size spec table | Every measurement point, in every size, in centimetres β the actual numbers cutting and QC work from |
| Construction sequence | The stitching operations in order, with machine type and the quality check for each step |
| Bill of materials | Fabric, trims, labels and packaging, specified precisely enough to reorder identically next time |
Why It Matters When Choosing a Manufacturer
A factory that works from a proper tech pack is a factory that has a process β pattern grading, in-line QC checkpoints, a documented construction sequence. A factory that works from a reference photo and “make it similar” is guessing, and guessing is exactly where you get sample-to-sample inconsistency, sizing that drifts between batches, and construction details that quietly change on reorders.
This matters even more for private label orders, where the whole point is that your design, your fit and your branding come back exactly as specified β not as “close enough.”
How to Tell If a Manufacturer Actually Uses Tech Packs
- Ask to see a sample tech pack for a style similar to yours, before you commit to an order.
- Check whether it includes a full size-by-size spec table, not just one sample size.
- Look for a construction sequence with named quality checks β not just “sew together.”
- If you supply your own design, ask whether they’ll build you a tech pack back for approval before cutting starts.

Rather than just tell you we work this way, we’ve published our own tech packs β the same level of detail every private label client gets, built around their own design.

Frequently Asked Questions
Do I need to supply my own tech pack to order private label?
No. You can send a reference design, photos or a rough sketch, and we build the tech pack for your approval before any cutting starts. If you already have one, that’s welcome too β it usually speeds up sampling.
Is a tech pack only useful for large orders?
No β it matters most for smaller, low-MOQ orders, since there’s no room to “fix it on the bulk run.” Getting the spec right at sample stage is what makes a small first order viable at all.
What’s the difference between a tech pack and a mood board?
A mood board communicates a look and feel. A tech pack communicates exact, measurable instructions a factory can cut and sew from. Most projects need both β the mood board at concept stage, the tech pack at production stage.
