For sweatpants we typically work with cotton fleece, French terry and loopback knits, choosing brushed or unbrushed backs depending on climate and target handfeel. Lighter options are suited to all-day indoor wear, while heavier fleece supports colder markets and streetwear segments that want more structure. Trims are specified as a package, including elastic waistbands, drawcords, aglets, rib cuffs, pocket bags and optional ankle zips. This integrated approach keeps comfort, drape, durability and price aligned with your positioning from entry to premium tiers.
