An ultralight base that can handle the heat.
An ultralight base that can handle the heat. When the heat’s on but you're still set on getting outside, this short-sleeve base layer is a must have. Made from our lightest fabric – a high-stretch, cooling yarn with a subtle dot graphic – this top works hard to keep you cool and dry. Perfect for running, hiking, or any circumstance where keeping cool and comfortable is critical. Seamlessly constructed so not even friction can slow you down. Ideal for those high-temp days when you want nothing holding you back.
