Helly Hansen Men's Odin 3D Air Shell Jacket The durable protection you need with the lightweight fabrics you want, the Odin Light 3D Shell Jacket is just that. With a Helly Tech Professional waterproof membrane, 3D printed backing to move the fabric away from your skin for better breathability and large ventilation zippers, you can regulate your temperature in all conditions while staying dry and comfortable. The design of the jacket was made with mountaineering in mind, which is why the hood still fits comfortably while wearing a helmet and the pockets can be used without any restriction when wearing a backpack. It also packs into it's own pocket, allowing you to throw it in your bag and head out on your next adventure.Fiber Content: Face: 100% Polyamide / Back: 100% Polyester Weight: 376g FEATURES HELLY TECH® Professional fabric 2,75L fabric construction with 3D backing Extreme ventilation Packable Light weight construction Helmet and backpack compatible design
