Two-layer training shorts with a built-in bike short
These 2-in-1 shorts pair a loose outer shell with a closer-fitting built-in bike short, so you can wear one garment for workouts or runs instead of layering two pairs. The lightweight, quick-dry, breathable materials suit sweaty training sessions, and the liner's cell phone patch pocket plus hidden side-seam slit pockets keep small items handy. An elastic waist with an adjustable inner drawstring lets you fine-tune the fit, and the reflective logo adds visibility.[1,2]
