What is a tech pack and why do wholesale buyers need one for custom orders?

A tech pack (technical package or specification sheet) is a comprehensive document that communicates every detail a manufacturer needs to produce a garment correctly — without ambiguity.

What a tech pack includes:

• Flat technical sketch (front, back, and detail views)
• Fabric specification (type, GSM, colour reference — Pantone or physical swatch)
• Measurement chart (all key dimensions for each size)
• Trim details (buttons, zippers, elastic, thread colour, label type)
• Embellishment details (embroidery placement diagram with measurements)
• Stitching specifications (stitch type, stitch per inch, seam allowance)
• Labelling requirements (size label, care label, brand label placement)
• Packaging requirements (folding method, polybag size, hang tag)

Why it matters: Without a tech pack, verbal and photo instructions lead to misunderstood specifications and costly sampling rounds. A good tech pack reduces sampling time and money significantly.
