As the name suggests, our Atomic Platinum Light liner is all about weight. Weighing in at a ridiculous 189g per boot thanks to the Ultralon Liner foam, it’s the perfect fit for our Backland Carbon Light boots, so you’re carrying even less up the hill. That said, it’s also one of the most advanced touring liners ever. It has a special waterproof and breathable mid-foot and bottom to allow excess heat and moisture to escape from both areas, keeping your feet drier, warmer and less prone to blisters. It’s also 100% safe to hand wash to keep the liner odor free.
