What should brands check before moving tracksuit production to a new factory?

Before moving tracksuit production to a new factory, brands should check whether the manufacturer can match both pieces as one complete set. Tracksuit production requires control of fabric hand feel, color consistency, jacket fit, pants fit, waistband elasticity, cuff tension, zipper quality, drawcords, labels, logo placement, and packaging. The top and bottom must look balanced when worn together, not like two separate products. Brands should provide approved samples, fabric swatches, tech packs, measurement charts, trims, and previous bulk comments. A PP sample should be approved before bulk, and the first production output should be checked to make sure fabric shade, fit, trims, and logo execution remain consistent.
