Description
Our new Boxer Brief Sport range has all the Step One benefits you know and love, with added features designed alongside world-class athletes to meet the specific needs of sportspeople.
The Boxer Brief Sport range is about 1.5 inches (4 cm) longer in leg length than our boxer briefs, meaning they stay-put and won’t ride up even during extreme movement. Plus, longer UltraGlyde panels = zero chance of chafe!
The fabric is the same breathable bamboo viscose that wicks away sweat and keeps you cool.
The 3D elastic pouch ensures everything stays where it should, even during rigorous exercise.
