Krypton Insulation Light Jacket

The KRYPTON INSULATION jacket is an ultra-light, high-performance insulated jacket. Designed for a FAST&LIGHT layer system, it combines the insulating protection and high breathability of Sorona Aura® DuPont® 40g fiber with the 100% windproof functionality of the exterior WindBreaker® fabric. Developed by using thermography and body mapping to combine plain sections with square baffles in key areas. Its hybrid construction results in a highly versatile and functional garment. The side pockets are positioned so as not to overlap with our FAST&LIGHT waterproof jackets.

The KRYPTON INSULATION jacket can be used as a second layer or third layer without the accumulation of hoods.
