Meet the OG shirt that put us on the map. Tired of heavy, sticky, overbuilt "performance" clothing, we hunted down the perfect lightweight fabric-crafted from bamboo-and built our first insanely soft and simple shirt: the Bamboo Lightweight Long Sleeve. That was back in 2011, and it's still a bestseller to this day. Buttery soft, lightweight, and equipped with a UPF 20 rating, it's the perfect layer for all your sun-soaked adventures when shade is hard to come by.
