Review the material in the actual garment.
Composition, surface feel, thickness, stretch direction, and the intended fit all contribute to material selection. A swatch can help establish the direction, but the finished garment needs review under the conditions relevant to its use. Color and size may also affect the appearance, so define the scope of any coverage assessment.
Terms such as squat-proof, compression, or moisture-managing should not be used as automatic descriptions of a fabric. If a specific benefit matters, agree how it will be evaluated and what evidence is needed. The product brief should connect the claim to the actual garment and intended wearer rather than rely on a supplier’s broad category language.
