A tech pack (technical package) is a fundamental document in the fashion industry. It serves as a detailed roadmap that guides the manufacturer through every step of the garment production process.
Why is a tech pack essential?
When a brand wants to produce a garment, it must ensure the manufacturer fully understands what needs to be done. Without a well-prepared tech pack, there is a risk of misinterpretation, which can lead to errors, delays, and additional costs.
The tech pack is especially useful when working with manufacturers located internationally, where language barriers can complicate communication. By providing a clear and structured document, the risks of mistakes are minimized, and production runs smoothly.
Detailed contents of a tech pack:
- Technical Flats
Precise and detailed drawings of the garment from multiple angles (front, back, side).
Includes construction details: types of seams, pocket placements, openings, finishes.
Allows the manufacturer to clearly visualize the design and structure of the garment.
- Construction Details
Explanation of assembly techniques:
🔹 Types of seams used (overlock, double stitch, etc.)
🔹 Reinforcement locations
🔹 Specific processes (embroidery, printing, dyeing)
Ensures the final product respects the original design.
- Fabrics & Materials
List of fabrics used, with exact references:
🔹 Composition (e.g., 100% cotton, polyester, linen)
🔹 Weight (e.g., 180 g/m²)
🔹 Type of knit or weave (jersey, twill, serge, etc.)
Details of trims:
🔹 Zippers, buttons, elastics
🔹 Labels and branding
- Sizing & Grading
Table with exact measurements for each size (XS, S, M, L, XL, etc.).
Instructions on grading (how sizes change from one to another).
Important to guarantee size consistency and avoid unexpected discrepancies.
- Trims & Details
Precise references of buttons, closures, elastics, rivets used.
Type of labeling (e.g., direct print or woven label).
- Manufacturing Instructions & Finishing
Specific instructions for garment assembly.
Particular requirements for finishing and quality.
Examples:
🔹 “All seams must be overlocked”
🔹 “Hems must be finished with a 5 mm double stitch”
- Testing & Quality Control
Quality control criteria to respect:
🔹 Seam strength
🔹 Dimensional stability (avoid shrinkage after washing)
🔹 Color fastness tests
Concrete advantages of a tech pack:
- Reduces errors: By defining everything upfront, misunderstandings with the manufacturer are avoided.
- Saves time: Fewer back-and-forths between designer and factory because everything is documented.
- Saves money: Fewer prototypes needed as instructions are clear.
- Production consistency: Garments made at different times have the same quality.
- Easier to switch manufacturers: A well-structured tech pack can be sent to any factory.
Who creates the tech pack?
- Fashion designer: Provides artistic direction.
- Product developer: Gathers technical details.
- Pattern maker: Provides measurements and pattern specifications.
- Manufacturer: Follows instructions to produce the final garment.
Practical examples of use:
- A clothing brand launches a new collection → A tech pack is created for each piece (t-shirt, pants, jacket).
- A designer wants to produce a prototype before mass production → Sends a tech pack to the factory to get a first sample.
- A company changes supplier → The tech pack ensures the new factory produces exactly the same garment.
A tech pack is essential for any brand that wants to produce clothing professionally. It serves as a precise plan to avoid mistakes, ensure quality, and facilitate large-scale production.
If you want to develop your own brand, having a well-structured tech pack is a key step to guarantee the success of your production!
