A tech pack is a collection of documents generated by the design team to describe their idea to a manufacturer so that it may be turned into a finished garment. Essentially, it is a communication tool used by designers and manufacturers. A tech pack also serves as a collaborative space in which designers, product developers, buyers, and quality control planners can collaborate.

Technical sketches (or fashion flats), building specifications, measurements, a Bill of Materials, and a price sheet are all common components of a tech pack. In this blog article, we will walk you through the process of creating a tech pack for apparel.

For this tutorial, we will use Techpacker product development software. Let's take a look at the structure Techpacker provides for creating a tech pack:

Techpacker provides a pre-set template for all essential tech pack elements:

  • Sketches with construction details;
  • Bill of Materials;
  • Measurements;
  • Costing Sheet;
  • One-click PDF generator.

In this post, we will create a jacket tech pack on Techpacker step-by step.

Sketches and construction details


Each tech pack begins with technical sketches (also known as fashion flats). They reflect the concept of how a garment should look when finished. Fashion flats should show every design feature from various angles. We recommend incorporating front and back views, as well as any close-up features when creating a tech pack for clothes. This will assist your factory and pattern maker in visualizing how to create the initial clothing sample to look as near to your desired product as feasible.

Technical sketches are often drawn in black and white using Adobe Illustrator. However, creating flat sketches on Ai requires some graphic design skills. Luckily there are some online vector editors available online that don’t have much of a learning curve. We like Repsketch as it provides a large open-source library of vector product sketches. This way designers do not have to create designs from scratch.

For this tutorial, we will re-purpose this jacket design from Repketch.
