Clothing Tech Pack Guide
Learning apparel production? BOMME Studio is a clothing manufacturer producing garments for established brands.
Clothing manufacturers rely on technical documentation to turn a garment concept into a production-ready product. In apparel manufacturing, this documentation is called a tech pack.
A clothing tech pack outlines the construction, materials, measurements, and specifications required to produce a garment accurately and consistently at scale. Without this documentation, manufacturers cannot properly estimate costs, develop samples, or maintain production quality.
This guide explains how clothing tech packs work, what information they contain, and how designers use them to communicate with factories. Want to see how a real tech pack is structured? Review our Clothing Tech Pack Example to see how garment specifications, BOMs, and spec sheets appear in a production-ready document.

What Is a Clothing Tech Pack?
A clothing tech pack is a technical document used by apparel manufacturers to build and produce garments. It acts as the production blueprint that communicates exactly how a garment should be constructed.
A production-ready tech pack typically includes:
- Technical flat sketches showing garment construction
- Bill of materials (BOM) listing fabrics and trims
- Measurement specifications and points of measure
- Construction instructions for seams and stitching
- Colorways and labeling details
- Packaging and finishing instructions
When prepared correctly, a tech pack allows manufacturers to estimate production costs, develop garment samples, and maintain consistency across production runs.
Without clear documentation, factories must rely on assumptions, which often leads to delays, mistakes, and inconsistent garments.
How Tech Packs Are Used in Apparel Manufacturing
In apparel production, tech packs serve as the primary communication document between brands and factories. They are used throughout several key stages of the manufacturing process.
- Product Development: Designers use tech packs to communicate garment construction and material requirements to manufacturers.
- Sampling: Factories use the tech pack to create prototype samples using the measurements, construction instructions, and material lists provided.
- Costing: Manufacturers rely on the bill of materials and construction details in the tech pack to estimate production costs.
- Production: Once samples are approved, the tech pack becomes the reference document used during cutting, sewing, finishing, and packaging.
Because the tech pack defines the garment in technical detail, it helps ensure production consistency across large quantities.
What Information Does a Clothing Tech Pack Contain?
While formats vary between brands, most production-ready tech packs contain several core sections.
- Technical Flat Sketches: Garment drawings that show construction from multiple angles and clarify panels, seams, pockets, and closures.
- Bill of Materials (BOM): A list of every material used in the garment, including fabrics, trims, labels, and packaging components.
- Measurement Specifications: Garment dimensions recorded using points of measure (POM), often including tolerance ranges.
- Construction Instructions: Notes describing seam types, stitching methods, seam allowances, and reinforcement details.
- Colorways and Labeling: Pantone references, woven label placement, care labels, and size labeling instructions.
- Packaging Instructions: Directions for folding, tagging, and packaging garments for shipment.
Common Tech Pack Mistakes Designers Make
Many early-stage brands experience production delays because their tech packs lack critical information.
- Missing measurement specifications
- Incomplete bill of materials
- Unclear construction details
- Inconsistent sketches and measurements
- Missing labeling instructions
These issues often require multiple sampling revisions before production can move forward.

Tech Pack vs Spec Sheet
In apparel development, the terms tech pack and spec sheet are sometimes used interchangeably. However, a spec sheet typically refers only to the measurement section of a tech pack.
A complete tech pack includes significantly more information, including materials, construction instructions, and production notes. Understanding the difference helps ensure manufacturers receive the full documentation required for garment development.
What Clothing Manufacturers Need Before Production
Before beginning production, manufacturers typically require several key pieces of information from brands.
- A complete tech pack
- Fabric and trim specifications
- Target production quantities
- Production timeline expectations
- Reference samples when available
Providing this information early helps streamline sampling and costing.
