The Rundown
An ultralight brief that can handle the heat.
Our lightest sports underwear brief is crafted with a high-stretch material and a specialised cooling yarn to wick moisture and keep your temperature just right when the heat's on. Seamless construction minimises chafing while ventilation zones offer breathable support exactly where you need it. The mid-rise cut provides fuller coverage for all-day ease. Perfect for running, hiking, or any circumstance where keeping cool and comfortable is critical. A barely-there layer for everything from mountain miles to city strides.
