Bridge the Gap Between Creative Vision and Bulk Manufacturing
A professional apparel tech pack is the ultimate blueprint for your garment. It serves as a legally binding technical document between fashion brands and cut-and-sew manufacturers worldwide. Without precise specs, sampling cycles multiply, costs increase, and final garments risk inaccurate sizing or stitching defects.
At Tack Apparel, our apparel technical designers transform sketches, reference photos, or physical samples into production-ready tech packs. We eliminate language barriers for overseas factories by utilizing standardized industry callouts, vector CAD illustrations, and exact Points of Measurement (POM).
- Detailed Vector CAD Flats with exact seam, stitch, and placement callouts
- Complete Bill of Materials (BOM) detailing fabric GSM, yarn count, and trims
- Comprehensive Measurement Tables with point-by-point tolerances
- Standard Size Grading Rules engineered across XS through 5XL range
