The perfect allrounder? Well proven fit and an innovative mix of materials makes Røros Box Down Light W Jacket a highly versatile, technical and packable garment. Box-wall construction utilizes the insulating capabilities of the down to the max and eliminates cold bridging. The shoulders are reinforced with a layer of synthetic insulation, PrimaLoft® Gold Insulation with Cross Core. This feature prevents cold bringing when you carry backpack, because the PrimaLoft® will not collapse under the weight of the shoulder straps. It also makes the shoulder panels more resistant to moist. The jackets outer fabric is made from 100% recycled polyamide, which is windproof, water-repellent and lightweight.
