The Men's Cosmo Jacket is constructed with a mixture of ultra-stretchy, breathable KJUS ski fabric with luxurious Lora Piana wool details. The combination of multiple technologies creates optimal temperature conditions. Starting with the insulation, the KJUS product engineers combine premium down with recycled cashmere. Then, they combined Graphene and a phase change material in the lining. These two technologies absorb, store and disperse heat when and where you need it.
