A great baselayer is the foundation of any good day on the hill, which is why we designed the Hoopler. Made from 77% nylon, 19% merino and 4% elastane, the Hoopler wicks moisture to moderate temperature, has enough stretch to enable maximum range of motion and is naturally odor resistant. Chafe-free flatlock seams and UPF 50 sun protection are perfect for long days on the hill, in bounds and out.
