What Exactly Is a Tech Pack?
A Tech Pack (Technical Packet) is the complete set of instructions a factory needs to build your garment exactly as intended. it's the construction document, the quality contract, and the pricing reference all in one. At Selvyna Atelier, we require a tech pack for every production run because it protects both the brand and the factory.
The Anatomy of a Professional Tech Pack
1) Technical Sketches (Flats)
2D drawings of front, back, and side views that show every seam, dart, and stitch line. Unlike fashion illustrations, flats are purely technical and measurable.
2) Bill of Materials (BOM)
- Primary Fabric: GSM/weight, fiber content, weave/knit type, Pantone color codes.
- Trims: Buttons, zippers (coil vs. metal, brand), toggles, drawcords.
- Labels/Tags: Brand label placement, care label content, size label positions.
- Packaging: Polybag type/thickness, folds, hang tags, barcode placement.
3) Graded Spec Sheet (Sizing)
Measurements for your base size (often M) and graded measurements for XS, S, L, XL. Includes tolerances (e.g., bust 38" ± 0.5") to ensure consistency and reduce returns.
4) Construction Details
Stitch types and placements (flat-lock for activewear, French seams for silk), seam allowances, fusing/interfacing, pocket placement, embroidery/screen-print dimensions.
5) Points of Measurement (POM) Diagrams
Visual arrows showing exactly where to measure (e.g., chest width 1" below armhole). This keeps factory QC and your team aligned on fit.
6) Packaging Instructions
Critical for e-commerce and Amazon FBA: folding method, polybag specs, FNSKU/GS1 barcode placement, carton labels.
Three Reasons Your Brand can't Survive Without a Tech Pack
1) It Prevents Sample Fatigue
Without a tech pack, factories guess. You pay for multiple samples as they iterate collars, fabrics, or measurements. A pro tech pack often nails the sample on the first or second try—saving hundreds in sample fees and weeks of delay.
2) It Unlocks Accurate Quotes
Factories can't price what they can't see. A detailed tech pack Let's us give to-the-penny quotes, eliminating "surprise costs" mid-production.
3) it's Your Insurance Policy
If bulk arrives off-spec, the tech pack is your evidence. When garments don't match the tech pack, the factory is responsible. Without it, you have no recourse.
