Featherweight comfort + sun protection.The lightest, most breathable sun shirts on the planet. That was our mission. Mostly because we don't like smearing sunblock all over our skin. Astonishingly featherweight fabric that the air blows right through. UPF 30+ sun protection so you'll never get sunburned. The magic is in the near weightless fabric. Our NoFry Sun Shirt weighs in at only 105g in a size medium. 81g for the short sleeve and 118g for the hoodie. The fabric itself comes in at just 79gsm.The thin, breathable fabric allows the shirts to pack down incredibly small & feel weightless on the body. Ideal for adventure travel or any long day in the sun. These shirts dry incredibly fast and wick moisture making them perfect for every possible outdoor activity and making it easy to rinse and hang dry when needed.
