The Atomic Backland Platinum liner is our most advanced touring liner ever. The perforated, breathable and waterproof construction allows excess heat and moisture to escape, keeping your feet drier, warmer and less prone to blisters. It is 100% hand washable in order to keep the liner fresh and odor free. Constructed from heat-moldable foam it’s also fully customizable, either as part of the Memory Fit process or separately on its own. And it’s super light, weighing in at only 242g.
