Tech Packs
The Ultimate Guide to Fashion Tech Pack (2026)
Every great garment starts with a great plan.
You've sketched the design, picked the colors, and you can already picture it on the rack. But between that idea and a finished product is one key document. It decides if your first sample is correct, or needs several redos: the tech pack.
This is the ultimate guide to the fashion tech pack. Below you'll find what it is, what goes inside, how to build one step by step, and a ready-to-use tech pack you can copy for your next style. Whether you're launching your first collection or scaling an existing line, this is where clear production starts.
If you are launching a clothing line, sending only a sketch to a factory can lead to costly delays and errors. A tech pack helps you avoid these issues.
This guide explains what a fashion tech pack is and why it's important for product development. It shows you the main parts of a professional tech pack, like technical sketches, measurements, and construction details. You'll also find information about materials, trims, colorways, labeling, packaging, and quality requirements. With this information, your manufacturer will receive straightforward, consistent guidance.
You'll learn how to make a tech pack step by step. Start with your design specs and fit standards. Then organize details for sampling and production. The guide also includes a tech pack template you can use and adjust for your next sample request. This will help you avoid mistakes, get faster approvals, and work better with factories and suppliers.
What Is a Tech Pack in Fashion?
A tech pack is a document that tells a manufacturer exactly how to make a garment. It covers the design, measurements, materials, construction, trims, labels, and packaging.
A tech pack is the recipe for your product. While a mood board shows the desired feel, a tech pack gives exact details for consistent production across factories.
Why Every Brand Needs a Tech Pack
- Fewer sample rounds. Clear directions reduce revisions, saving both time and money.
- Accurate quotes. Clear, detailed specifications empower manufacturers to provide precise pricing, ensuring there are no unexpected costs down the line.
- Consistency. The tech pack serves as the quality-control standard, ensuring every piece matches the original.
- Protection. In the event of disputes over defects or deviations, the tech pack serves as the agreed-upon standard.
- Easier factory transitions. If you change manufacturers, your specifications remain consistent.
A Complete Fashion Tech Pack Usually Includes These Sections
Cover Page
Style name and number, season, brand, designer, date, version number, and a small image of the finished garment.
Flat Sketches (Technical Drawings)
Include flat front, back, and side views, not shown on a model. Add close-up callouts for details such as pockets, cuffs, hems, and necklines. Ensure lines are clean and proportions accurate.
Bill of Materials
List every garment component, including main fabric, lining, thread, zippers, buttons, drawcords, elastic, labels, and packaging. For each, specify the supplier or specification, color, and quantity per garment.
Measurements (Spec Sheet)
Provide garment measurements for each size, including acceptable tolerances. List points of measure such as chest, waist, hem, shoulder, sleeve length, and inseam, and note how each is measured.
Structure Specifications
Detail stitch types, seam finishes, stitches per inch, topstitching placement, and reinforcement points. For knitwear, include gauge, yarn type, and finishing methods such as linking or flatlock seams.
Colorways and Artwork
Include Pantone or color references, precise print and embroidery placement with dimensions, and logo files.
Labels and Packaging
Specify main label, care label, size label, hangtags, and instructions for folding, bagging, and boxing the finished garment.
Generic Tech Pack vs. the Purl Studios Template
Search for a tech pack template, and you'll find plenty of free downloads. Many are useful starting points.
Yet, designers create most of them to adapt seamlessly to any garment or factory setting. So they often miss the details that matter for your product.
Here's how a typical generic template compares with the Purl Studios template:
| Features | Typical Generic Template | Purl Studios Template |
|---|---|---|
| Built for | Any garment, any brand | Activewear, workwear, and knitwear |
| Category-specific fields | Rarely included | Prompts for stretch and seam comfort, durable stitching and reinforcement, and gauge and yarn type |
| Made with a manufacturer's input | Often created by design or software brands | Shaped by how garments are actually produced and sampled |
| What happens next | You download it, fill it in, and figure out the rest | Fill it in, then send it straight to our team for review and a quote |
| Support if something's missing | None | We flag gaps before sampling, not after |
A generic template will get you a document. A template built around production gives you a document a factory can quote and sample, with fewer questions and fewer revisions.
Already Have Your Own Tech Pack? Upload It.
Not everyone wants to start from a new template, and you don't have to. If you've already built a tech pack in Illustrator, Excel, a tech pack app, or any format that works for you, upload it directly to Purl Studios.
Here's how it works:
- Upload your tech pack through our site, in the file format you already use.
- Our team reviews it for missing measurements, unclear construction notes, and material gaps.
- You get a clear quote based on your specs, along with feedback on anything that could delay the project.
There's no need to reformat your work into our template first. Bring what you have, and we'll work from it.
Common Tech Pack Mistakes
- Vague or missing tolerances. Without clear tolerances, acceptable variance becomes subjective.
- Inconsistent measurements. Ensure the spec sheet, sketch callouts, and grading rules are aligned.
- Omitting the BOM. Missing trims frequently cause production delays.
- Lack of version control. Distributing different versions can result in incorrect samples.
- Overdesigning the first sample. Focus on fit and construction before adding complexity.
- Ignoring category differences. Activewear requires stretch recovery and seam comfort specifications; workwear requires durability and reinforcement details; and knitwear requires gauge, yarn, and shrinkage allowances.
Tech Packs by Garment Type
The core structure remains consistent, but specific details vary by garment type:
- Activewear: stretch percentage, moisture-wicking fabric specs, flatlock seams, and fit at movement points.
- Workwear: heavy-duty stitching, bar tacks at stress points, fabric weight, and pocket construction.
- Knitwear: yarn type and count, gauge, stitch pattern, neckline and rib finishing, and pre-wash shrinkage allowance.

Do You Need a Tech Pack to Work With a Manufacturer?
A tech pack is the standard for obtaining accurate quotes and samples, but it does not need to be perfect at the outset. Many new brands begin with a sketch and a reference garment. A reliable manufacturing partner can help you develop a complete tech pack, which is often the best first step for those new to production.

Tech Pack FAQ: Answers From Purl Studios
What is a tech pack in fashion?
A tech pack is the technical document that tells a manufacturer exactly how to make your garment. It brings together flat sketches, measurements, materials, construction details, and labeling in one place, so the factory builds what you designed instead of guessing. At Purl Studios, it's the first thing we look at when we start a new style.
What should a tech pack include?
A complete tech pack has a cover page, flat sketches, a bill of materials, a spec sheet with tolerances, construction notes, colorways and artwork, labeling and packaging details, and a revision log. Our Purl Studios tech pack template covers all these sections, so you can fill it in, style by style, without wondering what's missing.
Who creates a tech pack?
Usually, the designer or brand owner, sometimes with help from a technical designer or pattern maker. If you're new to production, you don't have to do it alone. Our team can help you turn a sketch or reference garment into a clear set of specs.
Is there a free tech pack template?
Yes. Use the Purl Studios tech pack template. It's built for the categories we make: activewear, workwear, and knitwear. It asks for details like stretch and seam comfort. It also asks about durable stitching and reinforcement. It covers gauge and yarn type too. Copy it into a spreadsheet or document and adapt it to each style.
How long does it take to make a tech pack?
A simple garment can take a few hours, and a complex one may take several days, depending on how much detail you already have. Starting with our template usually speeds things up, since the structure is already in place.
Can Purl Studios review my tech pack before I place an order?
Absolutely! Just send us what you have, and our team will carefully review it for any missing measurements, unclear construction notes, or material gaps that might slow down sampling or production. Once everything is clear, we'll provide you with a straightforward quote tailored to your specifications.
What if I only have a sketch?
That's fine. Many brands start with a sketch or a garment they want to replicate. We'll help you build it out into a full tech pack, so you can move to sampling with confidence.
