A tech pack (technical package) is one of the most essential tools in fashion product development. It serves as a blueprint for manufacturers, detailing every specification needed to turn your design into a physical product. Without a tech pack, communication gaps can lead to costly mistakes, production delays, and inconsistencies in the final product.

In this guide, we’ll break down the anatomy of a tech pack, explain why it’s crucial for your fashion brand, and walk you through the step-by-step process of creating one. Whether you’re launching your first collection or refining your workflow, understanding tech packs will help you reduce sampling errors, streamline production, and maintain quality control.

What Is a Tech Pack and Why Is It Important?

A tech pack is a comprehensive document that outlines all necessary information for garment production. It typically includes detailed sketches, fabric specifications, measurements, construction details, colorways, trims, and labeling requirements.

Why Do You Need a Tech Pack?

1. Reduces Errors and Miscommunication

   A well-structured tech pack ensures that manufacturers fully understand your design specifications, minimizing costly misunderstandings.

   
   

2. Speeds Up the Production Process

   With all details clearly defined, factories can produce accurate samples faster, reducing the number of revisions needed.

   
   

3. Helps Maintain Consistency Across Orders

   If you’re producing the same style in multiple batches or colors, a tech pack serves as a reference point to ensure consistency.

   
   

4. Essential for Costing and Pricing

   Manufacturers use tech packs to calculate production costs, helping you budget effectively and set profitable price points.

The Anatomy of a Tech Pack

Every fashion tech pack follows a structured format that includes the following components:

1. Cover Page

The first page should include:

• Style number and name

• Season and collection name

• Brand information

• Designer’s name and contact details

• Date of creation and version control (to track updates)

2. Technical Sketches (Flat Drawings)

Clear black-and-white technical drawings provide a visual representation of your design from different angles, typically:

• Front and back view

• Side views (if applicable)

• Detail sketches for special elements like pleats, zippers, or stitching

3. Fabric and Material Specifications

List all fabrics and trims used in the garment, including:

• Fabric composition (e.g., 100% organic cotton)

• Weight and GSM (grams per square meter)

• Finishes (e.g., water-resistant coating)

• Source or supplier details

4. Colorways and Print Placement

If your design comes in multiple colors or has prints, include:

• A color swatch reference (Pantone codes are ideal)

• Print size and positioning

• Instructions for digital or screen printing

5. Measurement Specs and Grading

A measurement chart is critical for sizing accuracy, including:

• Garment dimensions for each size

• Points of measurement (POM), such as bust, waist, hip, sleeve length

• Tolerances (+/- allowed variations in measurements)

• Grading rules for different sizes

6. Construction and Stitching Details

Manufacturers need clear assembly instructions, including:

• Stitch types (e.g., overlock, flatlock)

• Seams and finishes

• Specific construction notes (e.g., reinforced stitching at stress points)

7. Trims, Labels, and Accessories

Provide detailed specifications for:

• Zippers, buttons, and fastenings

• Label placements (brand tags, size labels, care instructions)

• Packaging details (e.g., tissue paper, polybags, or hangtags)

8. Sample Comments and Revision Log

Since initial samples rarely come out perfect, you should have a revision log to:

• Track changes made to the sample

• Record factory feedback and necessary adjustments

• Keep an organized history of tech pack versions

How to Create a Tech Pack: Step-by-Step Guide

Step 1: Start with a Template

To save time, use a tech pack template with pre-structured sections. Many designers create tech packs using Adobe Illustrator, CLO3D, or dedicated PLM software like Matter PLM.

Step 2: Create Clear Technical Sketches

Make sure your flat sketches are precise, scalable, and labeled with callouts for design elements. Avoid artistic renderings—factories need technical clarity, not fashion illustrations.

Step 3: Define Fabric and Material Details

Include all material specifications in a table format to keep information clear and easy to reference. If working with sustainable fabrics, include certification details (e.g., GOTS, OEKO-TEX).

Step 4: Develop a Comprehensive Measurement Chart

Use industry-standard sizing charts as a reference, ensuring each measurement is precise. Keep in mind grading rules to scale sizes correctly.

Step 5: Specify Construction Techniques

Break down each step of the garment's construction, specifying seam types and finishing techniques to ensure durability and quality.

Step 6: Add Color, Print, and Trim Details

Ensure all color variations are documented using Pantone codes, and that print placements are illustrated clearly with scale references.

Step 7: Organize the Sample Review Process

Once a sample is produced, update the tech pack with comments on necessary adjustments, and keep a record of factory feedback to avoid repetitive mistakes.

Best Practices for Creating a Professional Tech Pack

1. Be as Detailed as Possible

   The more information you provide, the less room there is for error. Always assume the factory has no prior knowledge of your brand’s expectations.

   
   

2. Use Universal Measurement Units

   Stick to centimeters or inches consistently across the tech pack.

   
   

3. Label Everything Clearly

   Each sketch should have callouts pointing to specific features like seam lines, trims, and stitching types.

   
   

4. Keep It Organized

   Ensure the tech pack is well-structured, easy to read, and updated regularly to reflect changes.

   
   

5. Use Software That Streamlines the Process

   PLM (Product Lifecycle Management) systems like Matter PLM help designers manage, update, and track tech packs efficiently.

Conclusion

A tech pack is an essential tool for any fashion designer or brand looking to streamline production, reduce errors, and maintain quality consistency. While creating one may seem overwhelming at first, using a structured approach will save time, reduce costs, and improve communication with manufacturers.

By following these steps and best practices, you can ensure smooth production, minimize sample revisions, and build a more efficient workflow for your fashion brand.
