We love Outdoor Research for the technical apparel and gear they're able to produce for our adventures outdoors. But, the fun doesn't stop at their technical apparel. OR's Weisse Shirt is crip and clean with everything you need to enjoy summer days, brewery hopping, and concerts in the sun. UPF 30 means you can stay out as long as you like to, and the hemp and organic cotton blend will keep you cool throughout your day. This shirt is made sustainably from organic materials and it's designed to be a classic fit that works for everyone.
