Our Atomic Platinum liner is the most advanced touring liner ever. The perforated, breathable and waterproof base allows excess heat and moisture to escape, keeping your feet drier, warmer and less prone to blisters. Its unique construction is 100% hand washable to keep the liner fresh and odor free. Constructed from Ultralon foam it’s also fully heat moldable, either as part of the Memory Fit process or separately on its own. And it’s super light, weighing in at only 229g.
