QC & Risk Notes
Modal and bamboo blends outperform pure cotton in moisture management. Nylon-spandex blends offer support but can trap heat. Common mistakes in this category include: Ignoring seam type on inner thighs; Not confirming waistband width; Skipping fabric composition check. Always verify these points during the warehouse QC stage before approving international shipping.
