How to Create a Tech Pack for Custom Boardshorts

Published: 2026-02-03

A tech pack (technical pack, or spec sheet) is the document your factory uses to make your product. A clear tech pack is the single biggest factor in getting an accurate sample on the first try — and in avoiding expensive production mistakes. This guide covers what a boardshorts tech pack should contain.

What Is a Tech Pack?

A tech pack is a specification document that translates your design idea into production instructions. It tells the factory exactly what to cut, sew, print and pack. It combines a visual (flat sketch or technical drawing) with written specifications and measurement tables.

1. Style Overview

• Style name and number, season, target customer.
• Silhouette: boardshort, swim trunk, volley short or 2-in-1.
• Reference images or a flat technical sketch (front and back).

2. Measurements and Size Grading

Provide a measurement table (points of measure) in your target sizing system — for example waist relaxed/stretched, outseam, inseam, leg opening, hip. Include your size range (e.g. S–3XL for men, 2–14Y for kids) and grading rules. This is the most important section: vague measurements are the number one cause of rejected samples.

3. Fabric and Trims

• Fabric composition (e.g. 88% polyester / 12% spandex), weight (GSM), stretch and finish.
• Lining: mesh liner, compression short, or none.
• Trims: drawstring cord and tip, eyelets, elastic, thread, labels.

4. Construction Details

• Waistband type: elastic, fixed, or drawstring with hook-and-loop / lace-up closure.
• Seam types, stitch types and stitch density.
• Pocket type and placement (with drainage if required).
• Liner attachment method.

5. Print, Color and Artwork

• Print method: sublimation / all-over print, screen print or embroidery.
• Print placement and size, plus high-resolution artwork files.
• Pantone or color references for solids and trims.

6. Labels, Branding and Packaging

Main label, care label, size label, hangtag, polybag and carton details. Include artwork for every printed element, and note any compliance requirements (care symbols, fiber content, country of origin).

7. Reference Sample

If possible, send a physical reference sample — either your own previous product or a competitor short you admire. A physical reference removes ambiguity far better than words.

Tips to Avoid Costly Mistakes

• Use one tech pack per style and color.
• Keep measurements in a single consistent unit and system.
• State tolerances (acceptable +/- range) for each measurement.
• Send artwork in the correct format and color mode (often vector, CMYK or Pantone).
