The new material is 7x more breathable and allows 5x more air to pass through than regular underwear. The new material is also 20% lighter, resulting in extreme comfort. A new era in underwear has begun. Our Boxer Brief Sport Cloud Mesh range is made from 83% viscose made from bamboo, 9% elastane and 8% polyester. 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 4cm 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 3D elastic pouch ensures everything stays where it should, even during rigorous exercise.
