2-in-1 Training Shorts
The PrimeBuild™ Men's 2-in-1 Training Shorts are lined athletic shorts for men who run, train at the gym, or do HIIT and cardio, with a quick-dry outer short, a close-fitting inner compression liner and a zippered back pocket. These shorts pair a light, quick-dry outer short with a close-fitting inner liner. The liner keeps everything in place when you sprint, squat or jump, and the split outer hem lets your legs move freely. Your phone and keys ride in the zip pocket at the back or in the pocket on the liner, so nothing bounces.
Why it works
a quick-dry outer short over a close-fitting inner liner, in one garment.
the inner compression layer is designed to help reduce chafing and keep the shorts from riding up.
a zippered back pocket plus a phone pocket on the liner.
quick-dry fabric with laser-cut ventilation holes on the back.
split side hems give room for long strides and deep squats.
elastic waistband with an inner drawstring.
