Far more than just a hat, the Helios is a technical protector, with an Ultraviolet Protection Factor of 50+ to ward off the most intense sun. Its water-resistant double weave ripstop is extremely tough and durable. Go exploring anywhere – the headband wicks moisture from your brow and head, and the hat dries quickly. A one-hand adjustable & removable cord and a foam-stiffened brim have you on the longer trails in comfort. Pack it up small when transitioning between destinations.
