Tech pack checklist

Tech pack checklist for garments and consumer products

Last updated: November 2026 · Published by Cydney Mar

A garment tech pack is the technical document a factory uses to quote, sample, and produce your product, and it is the single biggest lever on how many sampling rounds a launch needs.

What goes in a tech pack for a garment?

A garment tech pack typically includes flat sketches, measurements and grading, materials, trims, colors, construction details, labels, packaging instructions, and a revision log. Cydney Mar describes a clear, professional tech pack as the difference between a sample that is right the first time and months of expensive back-and-forth.

Tech pack checklist: the sections to include

Garment tech pack sections, from The Product Launch Checklist by Cydney Mar
Section	What it tells the factory
Flat sketches	Front, back, and detail views of exactly what to make
Measurements and grading	Each measurement point, tolerances, and how sizes scale
Materials	Fabric or base material, weight, content, and approved swatches
Trims and components	Zippers, buttons, thread, hardware, and their placement
Colors	Color references for every material and trim
Construction	Seams, stitching, finishes, and assembly order
Labels	Brand, care, and content labels, with placement
Packaging	Folding, bagging, tags, and how units are packed for shipping
Revision log	What changed, when, and which sample it applies to

Why tech packs decide your launch date

Missing details become extra rounds

When a measurement, material, or stitch is missing, the factory has to guess. Each wrong guess is another sample, another shipment, and another wait. A complete tech pack is the cheapest way to protect your timeline.

Not only for garments

Candles, jewelry, homewares, paper goods, and accessories need specs too: dimensions, materials, finishes, tolerances, and packaging. Cydney Mar has developed products across all of these categories, and the principle is the same: write it down so nobody guesses.

Common tech pack mistakes

Measurements without tolerances
Color names instead of references
No revision log between samples
Packaging left for later

Need a production-ready tech pack?

Production-ready tech packs that factories understand, along with sampling, sourcing, costing, and production readiness, are the core of Cydney Mar's product development work. To talk about your product, contact Cydney Mar, or continue with the production readiness checklist.

Common questions

What is a tech pack for a garment?: A tech pack is the technical document a factory uses to make your product. For a garment it typically includes flat sketches, measurements and grading, materials and trims, colors, construction and stitching details, labels, and packaging instructions. A complete tech pack lets a factory quote accurately and produce a sample that matches what you intended.
Why does a tech pack matter for my first sample?: In Cydney Mar's words, a clear, professional tech pack is the difference between a sample that is right the first time and months of expensive back-and-forth. When details are missing, factories guess, and every guess can become another sampling round. Production-ready tech packs that factories understand are central to her product development work.
What if my samples keep coming back wrong?: Repeated wrong samples usually point to an incomplete tech pack, unclear feedback, or a supplier that is the wrong fit for the product. Review the tech pack for missing measurements, materials, or construction details, give written feedback with photos each round, and ask whether the factory has made similar products before. The tech pack checklist lists what to include.
How many prototypes do I need?: There is no fixed number. You need as many rounds as it takes to approve a sample that matches your spec, and the goal is fewer rounds, not more. That is why Cydney Mar's pathway focuses on developing the right samples to cut costly rework. A complete tech pack and clear written feedback on each round help reduce the count.
What kinds of products does Cydney Mar help with?: Cydney Mar focuses on consumer products for retail, TV, and direct-to-consumer brands. Over her career she has created fashion, jewelry, bath bombs, scented candles, homewares, paper products, car accessories, and her own Cydney Mar Wellness vitamins and supplements. Her core craft is product development: tech packs, sampling, sourcing, costing, and production readiness.
How do I choose the right supplier?: Vet suppliers for quality, communication, and reliability, the three criteria in Cydney Mar's pathway. Ask for samples, notice how quickly and clearly they answer questions, confirm minimum order quantities and lead times in writing, and compare more than one option. A cheaper supplier who misses dates can end up costing more than a reliable one.
