Product details

Fabric That Works in Motion

The four-way stretch construction allows flexible movement during wear. Flat seams help limit surface friction under additional layers. The top uses standard garment contouring, and the waistband maintain placement during motion. The low-bulk fabric composition allows unrestricted movement without deformation or sagging. With structured fitting, the set suits functional use under work gear, jackets, or uniforms.
