From the first blossom to the crisp days of fall, Atlas Long Sleeve delivers hyper-comfort and hyper-articulation in equal measure, keeping you on track and the trail long past peak summer.

Atlas rocks spandex-free, quick-wicking and breathable UPF 30+ fabric that excels on the hottest days of the season with a clean finish watch access flap doubling as a thumbhole. If you're deciding between shirts, Atlas is more articulated than Roam, with an extended reach forward and a slimmed-out bicep shape. Worn on its own in the heat or as a first layer on cooler days, Atlas is as adaptable as it is comfortable.
