What to Include in a Clothing Tech Pack

A clothing tech pack is the working product specification shared between the buyer and manufacturer. It should make the intended garment reviewable and reduce decisions that would otherwise be left to assumption.

Product identity

Give the style a stable name or reference code. Include front, back and relevant detail views. State the intended category, wearer group, fit and use. Record the document version and date so later comments are applied to the correct file.

Bill of materials

List the main fabric, rib, lining, interlining, mesh, elastic, thread, zipper, buttons, snaps, drawcord, eyelets, labels and packaging components that matter to the style. Describe composition, construction, target weight or thickness, colour and finish where known. Mark any item that may be proposed by the manufacturer.

Measurements and grading

Provide points of measure, measurement method, base size, size range, grade rules and tolerance proposal. A sketch showing exactly where each measurement is taken prevents different interpretations of the same label.

Construction details

Show seam, hem, pocket, collar, hood, cuff, waistband, closure, reinforcement and lining requirements. Note stitch appearance or construction only where it is important to the product. Use enlarged detail drawings for areas that cannot be understood from a flat sketch.

Artwork and decoration

Attach usable artwork files and define dimensions, colours, placement and method direction. State whether the requirement is embroidery, screen printing, sublimation, heat transfer, patching or another process, while allowing the method to be reviewed against the fabric and design.

Branding and packaging

Include neck label, size label, care label, country-of-origin information, hangtag, barcode or sticker requirements, polybag or other individual packing, folding direction and carton marks. Destination-market text and compliance requirements remain the buyer's responsibility unless otherwise agreed.

Approval record

Keep sample comments, approved revisions and open points in one controlled record. Do not rely on scattered chat messages as the final production instruction.

A tech pack can begin incomplete, but missing decisions should be identified before quotation or sampling. The final bulk specification should be the approved version rather than the first draft.
