Designed for adventures higher up the mountain, our Nevis puts the focus on high performance and functionality. The 3-layer GORE-TEX upper panels provide exceptional winter weather protection, while the abrasion-resistant polyamide stretch lower panels protect against rocks, scuffs and misplaced crampon spikes. The three size fit goes by height as well as shoe size to give a better indication of calf length. The reliable hook and loop closure with snap fastener provide a secure fit, creating an effective protective sleeve around the top of the boot and lower calf, keeping out loose debris as well as the elements.
