Your basecamp to beach companion, our new Tributary Hoodie! Bamboo is a super fabric - soft, naturally sun protecting, odor resistant and wicks moisture. That's why we decided to create our base layer sun shirt hybrid in a bamboo spandex blend. It's as cool looking as it is versatile. It's awesome in warm weather as well as a great base layer for cooler temps. With a hood and longer sleeves featuring thumb loops, you'll get the ultimate protection from the sun wherever your adventure might take you!
