X-Bionic Invent 4.0 LT Men's Boxer Shorts XXL - Opal Black/Arctic White

Intense workouts and cold-weather training often lead to overheating, sweat buildup, and uncomfortable chafing. The X-Bionic Invent 4.0 LT Boxer Shorts tackle these issues head-on with advanced thermoregulation and targeted ventilation, keeping you dry and comfortable from the first mile to the last.

Tips

For best results, wash these boxer shorts inside out with similar colours and avoid fabric softeners, which can clog the technical fibres and reduce their moisture-wicking performance. Pair them with X-Bionic baselayer tops for a complete thermoregulation system.
