Product FAQ

01 How should I choose my size?

Use the size guide on the product page and compare your measurements with the listed chest, waist and hip ranges. For a more relaxed fit, consider choosing the next size up.

02 Are the fabrics moisture-wicking?

Selected PeakWear styles use performance fabrics designed to move moisture away from the skin and support greater comfort during training, running and active routines.
