What Is a Tech Pack in Apparel Manufacturing?
A tech pack is the central contract and blueprint of clothing production. It translates creative fashion ideas into precise industrial manufacturing specifications.
General industry knowledge • Reviewed by Fenalt editorial team
A tech pack is an exhaustive instruction document containing flat vector sketches, measurement tables, bill of materials, colour references, and construction callouts.
In global clothing production, manufacturers build garments based strictly on technical specifications. Without a tech pack, pattern makers and sample machinists must interpret design intent, leading to inaccurate prototypes, extra revision costs, and production delays. A complete tech pack serves as the master contract between brand and manufacturer.
Document Structure
8 Essential Pages Inside a Professional Tech Pack
1. Cover Page & Style Summary
Establishes style identity. Contains 2D vector sketches (front/back), style name, style number, season, date of creation, revision history, and target garment category.
2. Flat Technical Sketches & Construction Callouts
Black-and-white 2D CAD vector drawings detailing seam placement, pocket openings, topstitching widths, collar construction, hem finishes, and hardware attachment instructions.
3. Fabric & Material Specifications
Specifies primary shell fabric, lining, ribbing, interlinings, and pocketing - including fibre composition, yarn count, weight in GSM, and finish requirements.
4. Colorway Specification Sheet
Lists Pantone (PMS TCX or C) codes for every fabric, thread, print, and trim element to eliminate subjective dye lot discrepancies.
5. Bill of Materials (BOM)
An itemised master table listing every component required to manufacture the garment - fabrics, threads, zippers, buttons, woven labels, care tags, hangtags, and polybags.
6. Point of Measure (POM) Table & Tolerances
Lists flat dimensions for every key measurement point (chest width, body length, shoulder slope, sleeve length) along with acceptable industrial tolerances (±1.0cm to ±1.5cm).
7. Graphic, Artwork & Embellishment Specs
Details print or embroidery coordinates, artwork scale (cm), print type (screen print, DTG, puff print), embroidery thread colours, and backing specifications.
8. Packaging & Fold Specifications
Defines folding methods, polybag dimensions, barcode placement, hangtag attachment methods, and export carton packaging ratios.
Risk Analysis
What Happens Without a Tech Pack
Inaccurate Quotes & Price Surprises
Without exact fabric GSM, seam details, and BOM specifications, factories can only offer rough indicative quotes that increase once production details are clarified.
Multiple Failed Sample Iterations
Sample machinists force-interpret ambiguous sketches, resulting in misaligned sample revisions and wasted sampling fees.
Unenforceable Quality Control
QC inspectors need written POM tables and spec sheets to check measurements. Without a tech pack, quality assessments remain purely subjective.
Supplier Disputes Over Defective Runs
If bulk goods arrive with incorrect collar width or missing care tags, manufacturers are legally and commercially accountable only for specs documented in writing.
Questions
Frequently Asked Questions
What is a tech pack in garment manufacturing?
A tech pack (technical package) is a comprehensive blueprint document created by designers or technical designers to communicate a garment's exact physical, dimensional, and material specifications to clothing manufacturers.
Who creates a tech pack?
Tech packs are typically created by technical designers, apparel freelancers, or design studios. Managed production partners like Fenalt also provide technical design services to help emerging brand founders convert design sketches into factory-ready tech packs.
Can I get an accurate manufacturing quote without a tech pack?
No. Manufacturers can only provide rough estimates without a tech pack. Accurate unit pricing depends on fabric consumption, GSM weight, sewing complexity, trim specs, and size grading - all of which are defined inside a tech pack.
What file format should a tech pack be in?
Tech packs are typically formatted as multi-page PDF documents or structured spreadsheets (Excel/Google Sheets) with embedded vector graphics (AI/EPS/PDF format) for flat sketches and artwork.
Is a tech pack the same as a sewing pattern?
No. A tech pack is a specification document containing measurements, fabrics, trims, and construction rules. A sewing pattern consists of physical or CAD digital 2D templates used directly on the cutting table to cut fabric pieces.
How long does it take to create a tech pack?
Creating a complete tech pack for a standard garment (such as a hoodie or t-shirt) usually takes 2 to 5 business days for an experienced technical designer, assuming design specs and measurements are finalized.
