Is nylon or polyester better for custom tracksuit production?

Nylon is usually better when a brand wants a lightweight, crisp, premium, or technical streetwear feel. Polyester is often more suitable when the brand needs stronger cost control, color consistency, easy sourcing, and sportswear-style performance. For custom tracksuit production, the decision should not be based only on fabric name. Brands should compare hand feel, coating, lining, durability, shrinkage, noise level, color matching, and target retail positioning. A reliable tracksuit manufacturer should help test fabric swatches before sampling so the brand can choose the right material for the collection.
