Tracksuit and lower fabrics are selected around garment weight, drape, stretch, surface, warmth and finishing route.
Define the season and target garment weight.
Specify stretch direction, hand and whether a smooth, brushed or structured surface is required.
Include pilling, dimensional-stability, colour-fastness or other buyer targets where relevant.
Season, drape, warmth, surface and stretch should narrow the shortlist before sampling.
Ranking is deterministic and uses only current catalogue data: exact end-use tags, construction, stretch, GSM fit, family and listed properties. It is a sourcing shortlist, not a claim that one fabric is universally best.
Send the garment, GSM, width, stretch, finish, volume and testing requirements.
