How can brands avoid fabric, zipper, and trim delays before tracksuit bulk production?

Brands can avoid tracksuit material delays by confirming the BOM early. The BOM should include fabric, lining if needed, zippers, pullers, elastic, drawcords, labels, hangtags, packaging bags, carton marks, and any special trims. Color approval should also happen before bulk production, especially if the fabric or rib requires custom dyeing. For nylon or performance tracksuits, the brand should confirm fabric function, hand feel, weight, coating, and stretch before sampling is finalized. Mature brands do not wait until the bulk order is ready to ask about trims. They check material lead time early so the factory can prepare sourcing, lab dips, approvals, and production scheduling.
