As you'd expect from Satisfy, the AuraLite UV Long Tee ain't your normal running t-shirt. Designed with hot summer days in mind, it's a seriously lightweight long sleeve t-shirt made using the brand's very own Auralite™ UV fabric. Woven in Japan, this featherweight, breathable micro-jersey has been engineered to disperse moisture, dry fast and resist wrinkles. And if that wasn't enough-it features UV protection to keep those rays at bay. Continuing the theme of carefully-considered details, seamless construction cuts down on chafing, while those body-mapped mesh panels give even more breathability.
