Half-Zip Sweatshirt Tech Pack Template

A half-zip sweatshirt tech pack lives or dies on the relationship between stand collar height and zip length. This one specifies both as critical rows, alongside the cuff and hem ribs and a body block graded XS to XXL with tolerances — drawn with and without the bottom rib.

Why this one is different

Half-Zip Sweatshirt, specified

A half-zip is a crewneck with the neck rib removed and a stand collar put in its place, which changes two things at once: the collar has its own height row, and the zip length has to be specified against it rather than against the body. Both are flagged critical here.

Get the collar height wrong and it either folds over on itself or sits too low to do the job it exists for. Get the zip length wrong and the collar will not close flush at the top.

Stand collar height and zip length as paired critical rows, drawn with and without the bottom rib.

Points of measure

Every row in the pack

All 12 of them, with the convention each is measured to. 6 are marked as measurements a factory cannot cut without — they print in bold on the page. The values themselves are inside the document, graded XS–XXL with tolerances; we do not publish them here.

Measurements in this pack are drafted from published industry sizing (EN 13402-3 body girths; Craft Yarn Council body lengths) with standard ease for the stated fit class. They are a production-ready standard block, not White Cotton house measurements. Confirm the graded spec against your own fit sample before bulk production.

FAQ

Before you buy

Quarter-zip or half-zip — which is this?+

The zip length is a row you set, so the same document specifies either. What it fixes is the relationship: the zip is measured top stop to bottom stop and the collar height is specified independently, so changing one does not silently break the other.

Does it include the collar construction?+

The stand collar appears in the component list, on the inside-construction page with its seams named, and on the bill of materials alongside the zip.

What do I actually receive?+

A vector PDF and an .ai file, by email, immediately after payment. Both open and edit in Illustrator, Affinity or CorelDRAW — nothing is flattened or locked.

Can I use it with any factory?+

Yes. The document is yours and carries no supplier details — no address, no contact, nothing that ties it to us. It is drawn to industry convention so any factory can read it.

Are the measurements already filled in?+

Yes, as a production-ready standard block graded XS–XXL with tolerances, drawn from published industry sizing. It is a starting point you overwrite to match your own fit sample — the pack says so on the page. Your own fields (brand, style code, season, colourway names, artwork) arrive marked [FILL IN] in red so nothing ships carrying someone else's data.
