Functional running underwear forms the first layer that determines how dry and comfortable you feel throughout your run. Breathable materials actively wick away moisture, thermoregulation keeps you comfortable in both warm and cold weather, and a seamless design with support prevents chafing in high-stress areas.

When choosing, consider the material, level of support, and season. Our selection includes men’s models from Saxx, Sensor, and Under Armour, which combine function with a soft feel. Choose your base layer and have it delivered within 24 hours. You’ll appreciate the quality materials and thoughtful design every time you wear it, whether you’re heading out for a workout or a hike.
