Runderwear Running Briefs The Runderwear Men's Briefs are designed to ensure you can enjoy all your running adventures chafe-free, with maximum support and in ultimate comfort. Pull on breathable comfort where you crave it the most. Enriched with moisture-management technology, these briefs move sweat away from the skin for quick evaporation; so you stay damp-free and comfortable on longer distance days. The high-performance moisture-wicking fabric also features mesh panels which work to increase ventilation so you can remain cool, dry and comfortable at all times. Perforations within the fabric allow cool air to circulate throughout the garment, preventing an uncomfortable heat built-up, keeping you cool and comfy during intense exercise. The incredibly soft fabric sits comfortably against the skin whilst an ergonomic design moves with the motion of your body, letting you power on up those inclines with ease; because your clothing choice (least of all your underwear) should never inhibit your natural movement. Completing the briefs is a lightweight technical fabric which is highly durable for long-lasting use.
