Best-selling ActiveIce™ technology is upgraded for Spring 2021 to work more efficiently and effectively than ever before. Now featuring the same thermo-regulating formula as OR's proprietary ActiveTemp™, this new version of ActiveIce™ dynamically adjusts to your body’s temperature to cool you faster when you need it most. Still wicking and complete with a UPF 50 sun protection rating, ActiveIce™ is the perfect companion for anyone who spends serious time in hot, sweaty, sun-baked conditions. The ActiveIce Sun Gloves are the fingerless option for back-of-hand sun protection, with a grippy palm to keep hold of your trekking pole, ice axe, or bike handles.
