UPF 50 sun protective and made from 100% recycled bluesign certified fabric, the wicking sweatband and stretch-comfort adjustable sizing make it the perfect companion when temps rise. Reflective details and dark underbrim help get you noticed in low light while protecting your eyes when the sun shines bright.\n\nOur Verdict\nThe Flash Cap feels really comfortable with stretchy material, an easily adjustable strap at the back so you can change it while running without having to stop and also a high-wicking sweatband in it. Ideal for long-distance runs or hikes in the summer where other caps may feel tight and uncomfortable.\n- Reviewed by Ultralight Outdoor Gear\n\nFeatures\n\nUPF 50 sun rating (mesh not rated)\n100% recycled, wicking fabric\nDark underbrim reduces glare\nReflective details\nWicking sweatband/underbrim for maximum evaporation\nStretch comfort adjustable sizing\nbluesign certified main body fabric, mesh, and sweatband\nSunglass Lock keeps glasses in place\nPonytail-friendly\n\n\nSpecifications\n\nWeight: 57g\n2\
