Introduction to Tech Pack Examples for T-Shirts, Hoodies, and Denim
Creating a tech pack is essential for translating your apparel design—whether it’s a T-shirt, hoodie, or pair of jeans—into a manufacturable garment. A tech pack is the blueprint for your product, used by factories to bring your ideas to life with the right fit, materials, and details. In this guide, you’ll discover practical tech pack examples for T-shirts, hoodies, and denim, with a focus on key components, real-world templates, and actionable tips for effective apparel design communication.
What Is a Tech Pack and Why Does It Matter?
A tech pack, short for technical package, is a set of documents that communicates all the critical design, fit, and quality information to garment factories. It brings clarity to the manufacturing process, ensuring every detail—fabric choice, stitching, trims, measurements—is specified and mistakes are minimized. Apparel Wiki often receives questions about this, and it’s clear: a precise tech pack reduces surprises and expedites production success.
Essential Components in Every Apparel Tech Pack
Regardless of garment type, a robust tech pack includes:
- Technical drawings (front, back, and detail views)
- Bill of materials (BOM)—fabric, trims, and accessories
- Measurement chart for all garment sizes
- Construction and stitching details
- Colorways and artwork placements
- Labels, hangtags, and packaging instructions
- Special notes for quality control or finishing
How to Structure Your Tech Pack for Success
An easy-to-navigate structure ensures your tech pack is understood globally. Typically, start with a cover page (style name/code and version), then progress to visual references, materials, construction, sizes, and at the end, any unique requirements. For a deep-dive breakdown, explore the Anatomy of a Tech Pack for practical section-by-section guidance.

Visuals: Annotated Tech Pack Pages
Clear, detailed sketches with numbered callouts are critical. These make construction expectations obvious and minimize interpretation errors. When styling pockets, cuffs, or collars, add close-up drawings to prevent confusion. Practical callout writing tips can be found in guides like Clear Factory Communication.
Bill of Materials: Getting Specific
Your BOM should list every material, trim, or accessory—think main fabric, ribbing, threads, zippers, buttons, and labels. Include supplier codes, colors, and material weights. This lets factories source or substitute with confidence. Apparel Wiki recommends organizing your BOM with clear item descriptions and global availability for easier manufacturing handoff.
Measurement Charts for Each Apparel Category
Tech pack measurement charts are one of the most common causes of production delays if incomplete or unclear. For each style, list every Point of Measurement (POM) with diagrams showing how to measure. For a simple t-shirt, this means chest, body length, and sleeve length at minimum. Advanced resources like How to Measure a Garment: 9 Key POMs and Pro Tips for Perfect Fit provide deep dives for every type of apparel.
What to Include: Critical POMs for T-Shirts, Hoodies, and Denim
T-Shirts: Chest, Body Length, Shoulder Width, Sleeve Length
Hoodies: Add Hood Depth, Hem Width, Pocket Height
Denim: Inseam, Waist, Hip, Front and Back Rise, Leg Opening
How to Create a Measurement Chart
Use clear diagrams and logical order. Mark each measurement point with consistent abbreviations. For hands-on help, see How to Create a Measurement Chart for Development for step-by-step visuals and free templates.
Stitching and Seam Instructions—Why Details Matter
Every stitch type—from overlock to chainstitch—affects seam strength, stretch, and visual finish. For instance, T-shirts often call for a 2-needle topstitch at the hem, while jeans require heavy-duty double topstitch and bartacks for durability. Refer to technical guides such as What Is “Topstitching”? for explanations and examples.
Color, Artwork, and Placement Calls
Include color Pantone numbers (or equivalents), print/embroidery scale in centimeters or inches, plus exact placement from shoulder seam or hem. Artwork files should be attached in scalable vector format (AI, PDF).
Labeling, Hangtags, and Packaging
Don’t forget details like main labels, care/content instructions, and swing tag designs, especially for denim and hoodies where branding and care compliance are critical. State packaging specs—e.g., folded, packed in polybags, number of units per carton—to align with logistics needs.
Comments, Change Logs, and Version Control
Use clear, dated comments and a running change log—this keeps factories updated on recent revisions. For best practices, review Clear Factory Communication: 18 Game-Changing Techniques.
How Tech Packs Guide Sample Development and Bulk Production
During sample making, tech packs enable factories to construct prototypes accurately. Each change or fit revision gets updated into the master document, so bulk production proceeds without unwanted surprises.
Fabric and Trim Specifications by Category
T-shirts and hoodies rely heavily on knits, while denim is always a woven product. Understanding these differences avoids confusion. For a comprehensive look at fabric properties, see Developing Patterns for Knits vs Wovens.
Fit Guidelines and Tolerance Ranges
State tolerances (e.g., ±0.5cm for chest circumference). Communicate expected fit (relaxed, classic, or slim)—these terms vary globally; clarify your definitions to reduce fit disputes during production.
Quality Control Points: Stitch, Wash, and Measurement Checks
Highlight critical quality control steps: check all measurements against spec, verify correct trims/stitch types, and confirm washes (for denim) match approval standards. This ensures a professional outcome even with remote manufacturing.
Production Timeline Guidance
Map out sample due dates, fit review rounds, and delivery windows. Build flexibility for revisions—especially important with custom artwork or complicated construction, as in hoodies and denim.
Tech Pack Mistakes to Avoid
Common pitfalls include unclear measurements, missing artwork files, outdated revisions, and failing to specify stitch or packaging types. For an in-depth look at the most frequent errors, review Top Tech Pack Blunders: 15 Delays You Can Avoid.
Tips for First-Time Tech Pack Designers
- Start with a template matching your garment (e.g., t-shirt, hoodie, denim)
