A denim tech pack is the shared brief that lets design, PD, and a factory argue about the same facts. This guide shows what to put in before the first sample round—without inventing MOQ, lead times, or factory claims.
Search interest around clothing tech packs is rising for basic questions (“what is a tech pack in fashion”, “how to make a tech pack”, “tech pack template”). Buyers still often send a moodboard and a size chart, then wonder why wash and fit diverge. Use the sections below as a denim-oriented checklist you can paste into your own template.
What a denim tech pack must decide
- Product identity: silhouette, gender/market, season intent, and whether the face is knit denim or woven denim.
- Fabric direction: construction family, target weight band, stretch/recovery expectation, and any reference swatch IDs.
- Fit & measurements: graded POM chart, how to measure, and which sample size is the fit master.
- Construction: stitch types, pocket bags, waistband build, rivets/buttons, and label placements.
- Wash & finish: must-match vs directional effects, shade comments, hand comments, and which sample locks approval.
- BOM & artwork: fabrics, trims, threads, care labels, hangtags—with color/finish notes.
Anything you leave blank will be filled by assumption. Assumptions are where sample rounds multiply.
Minimum buyer inputs before sampling
- Front/back/detail reference photos (or a physical reference garment) with must-match notes.
- Construction callout: knit vs woven, plus stretch/recovery language if mobility matters.
- Size chart with tolerances and measurement method notes (flat vs on-body).
- Wash brief: shade, contrast, whisker/abrasion zones, hand priority.
- BOM list even if some items are “TBD—factory propose options.”
- Development stage (proto / fit / wash lock / PP) and what change forces re-approval.
Wash and fit: keep them on the same pack
Denim programs fail when fit is approved on one wash state and shade is approved on another. State whether measurements are before wash, after wash, or both. Link wash acceptance language to the same sample that locks fit when that is your process.
For effect language, see how to specify denim wash effects for sampling. For construction choice, see knit vs woven for product development.

When this applies
- You are briefing a first denim or knit-denim sample
- Fit and wash keep drifting between rounds
- Multiple stakeholders edit the brief in chat threads instead of a pack
Development risks
- Moodboards without must-match notes
- Missing knit vs woven callout on “stretch denim”
- Approving shade and fit on different wash states
- BOM gaps that surface only at PP
What buyers should provide
- References with priority notes
- POM method and master size
- Fabric / construction direction
- Wash acceptance language
- Revision owner and date on every pack version
