Sweatpants Fabric Weight
In typical development logic, 320 GSM is lighter, 400 GSM more structured, and 450+ GSM heavyweight. Final selection depends on the specification. This article separates example development decisions from confirmed product information so a brand can review the right details before sampling.
Example Development Specification
Example only: 400 GSM cotton fleece, relaxed or oversized fit, coordinated rib, defined artwork placement and a pre-production sample review. Final materials and measurements should follow the approved tech pack.
Construction and Sampling Checks
- Confirm fabric weight, composition and hand feel.
- Review fit, key measurements and seam balance.
- Check trims, artwork placement and color references.
- Record sample changes before bulk cutting.
- Use the approved sample as the bulk QC reference.
Questions Brands Should Answer Before Bulk
Which fabric and weight are approved? Which measurements are critical? How will decoration, color and trims be checked? What changes remain open after sampling? Writing these decisions into the product file reduces ambiguity between development and production.
