What Is a Tech Pack and Why Your Manufacturer Needs One
Discover what a fashion tech pack is, why it’s essential for production, and how Apparel Tech creates accurate, factory-ready tech packs that save brands time and money.
Introduction – The Bridge Between Design and Production
If you’ve ever had a sample come back from a manufacturer that looks nothing like what you imagined, the problem probably wasn’t the factory, it was the instructions. In the apparel industry, those instructions come in the form of a tech pack (short for “technical package”).
At Apparel Tech, we create precise, comprehensive tech packs that act as a blueprint for your garment, ensuring your vision is translated into production without costly misunderstandings.
1. What Exactly Is a Tech Pack?
A tech pack is a detailed document that communicates every essential aspect of a garment’s design to the manufacturer. It includes:
- Technical drawings (front, back, side views)
- Measurements & grading rules for different sizes
- Fabric and trim specifications
- Construction details (stitch type, seam allowance, finishing)
- Artwork placement for prints, embroidery, or branding
- Colourways for the collection
- Bill of materials listing every component
Think of it as an instruction manual for your garment. Without it, the factory is guessing.
2. Why Every Manufacturer Needs a Tech Pack
Without a clear tech pack, you run the risk of:
- Miscommunication – resulting in incorrect sizing, fabric, or construction.
- Costly resampling – each round of physical samples costs time and money.
- Production delays – unclear instructions slow down manufacturing timelines.
With a tech pack, your factory knows exactly what’s expected, which speeds up sampling, improves accuracy, and reduces wasted materials.
3. What Goes Inside a Professional Tech Pack?
At Apparel Tech, our tech packs include:
- Flat Technical Drawings
We provide clear CAD flats from multiple angles so manufacturers can see every seam, dart, and panel. - Measurement Specs & Tolerances
Every garment is measured to the millimetre, with tolerances so factories know the acceptable variation range. - Fabric & Trim Details
Precise information about fibre content, weight, finish, and source, along with details for buttons, zips, and labels. - Colourways
Pantone references or fabric swatch numbers to eliminate guesswork on shade accuracy. - Construction Notes
Stitch type, seam finish, hemming details, and any special assembly instructions. - Branding & Graphics
Exact placement and scale for prints, embroidery, heat transfers, or woven labels. - Common Mistakes Brands Make Without a Tech Pack
We’ve seen brands try to skip the tech pack step, and it rarely ends well. Common errors include:
- Sending inspiration photos instead of proper specs
- Omitting measurements or leaving them vague
- Forgetting to include tolerances
- Not specifying fabrics, leading to unexpected substitutions
These mistakes cost brands thousands in wasted samples and missed launch deadlines.
