Tech Pack

Definition

A detailed specification package used to communicate apparel or soft-goods design and production requirements to a manufacturer.

Overview

Tech Pack A detailed specification package used to communicate apparel or soft-goods design and production requirements to a manufacturer. Creating a practical tech pack requires organization, standard templates, and a process that maps design intent to factory actions.


The checklist below walks through steps designers and product teams should follow to produce production-ready tech packs. It focuses on items that reduce sampling cycles and prevent production surprises that affect cost, lead time, and inbound logistics.


Preliminary Steps Before You Start


  • Define scope: Decide whether the tech pack covers a single style, a family of sizes, or an entire line with shared BOM elements.
  • Gather assets: Collect sketches, moodboard images, fabric swatches, sample photos, and any lab test results you already have.
  • Select templates: Use a standardized tech pack template or a digital tech pack tool to ensure consistent fields and version control.


Step-By-Step Tech Pack Checklist


  • Title block: Include style name, SKU, season, brand, and a unique revision number.
  • Design visuals: Attach high-resolution flat sketches and annotated detail callouts that show all construction points.
  • Measurement spec sheet: Provide graded measurements for every size, method of measurement, and acceptable tolerances.
  • Bill of materials: List shell fabrics, trims, thread, interfacings, labels, and supplier codes where possible.
  • Construction notes: Specify seam types, stitch density, serging requirements, and assembly order for critical seams.
  • Hardware and trims: Add part numbers, plating or finish colors, and exact dimensions for zippers, snaps, and buttons.
  • Colorways and artwork: Include Pantone or color codes, placement files for prints or embroidery, and scalable vector files where required.
  • Care and compliance: State required care label language, fiber content percentages, and any mandatory testing standards.
  • Packing instructions: Document folding method, polybag spec, units per carton, carton dimensions, and outer label formats.
  • Quality checkpoints: Define in-line and final inspection points, AQL thresholds where applicable, and critical faults versus minor defects.
  • Approvals and samples: Attach photos of approved golden samples and record dates and approver names.


Integration With Production And Logistics


Once finalized, integrate the tech pack with purchasing and logistics by exporting SKU and BOM data to procurement systems and sending packaging data to warehouse partners. Include barcode or GS1 identifiers in the tech pack so label generation matches the master pack instructions and WMS expectations on receipt.


Common Pitfalls And How To Avoid Them


  • Missing tolerances: Always include numeric tolerances for measurements to prevent disputes at inspection.
  • Ambiguous notes: Replace vague language with specifics, for example specifying 'lockstitch in 3mm topstitch' instead of 'secure seam'.
  • Untracked revisions: Use version numbers and a change log so factories and warehouses know which tech pack is current.
  • No sample photos: Attach clear images of approved samples to show real-world appearance and construction.


Practical Example Checklist For A New Tee Shirt


  • Title block: Style name, SKU, colorway name, revision 01.
  • Sketches: Front, back, and sleeve detail with hem and collar callouts.
  • Spec chart: Chest, body length, shoulder width across sizes S to XL with +/- tolerances.
  • BOM: 100% combed cotton 180gsm, rib knit collar, neck label part number, wash care label text.
  • Construction notes: Single needle topstitch 3mm from seam, twin needle hem, bar tack at pocket corners if applicable.
  • Packing: Folded into clear polybag, 20 units per inner carton, 200 units per master carton, include carton barcode sticker sample.


In short, the Tech Pack is a project document that becomes the factory playbook. Following a clear checklist, standard templates, and good version control reduces sample rounds, cuts production risk, and ensures warehousing and shipping teams receive the documentation they need for smooth inbound and distribution operations.
