Play "Red Light, Green Light" all day long in this lightly insulated jacket.

The itinerary for your ice climbing tour of Norway has been finalized, and you just need to go over the gear checklist on more time. Softshell and midlayer? Check, as you have the Mammut Women's Biwak Light Jacket. This innovative piece of outerwear exploits new insulation technology to give you a lightweight, warm, and breathable puffy-style jacket without the extra puff factor. You can squeeze through small spaces or layer up when snow eddies cloud your vision, and you can do stop-and-go all day long without getting overly heated or sweaty.
On the outside, the Biwak combines water- and wind-resistant Pertex Quantum fabric in the front and back with Polartec Power Stretch Pro side panels. Your innards stay toasty, but you can still comfortably reach high for a hold or lean over to secure your crampon. Throughout the front and back, Polartec Alpha insulation works its magic to keep you warm without adding weight. This insulation uses high-loft, low-weight fibers in a low-density knit to give you a highly breathable insulation so you won't get sweat-soaked and then shivery when you stop mid-way up the mountain; make speed hiking a new sport and not fall prey to overheating, as this jacket lets the outside air in to keep the heat at a minimum.
Don't be fooled by the puffy pigeonhole—the Biwak Light sports a slim silhouette so you can layer over it when you need waterproof protection. Thumb loops at the end of high-reach sleeves accommodate overhead movement. Two side pockets and a chest zip pocket give you on-the-go storage options so you don't have to stop and drop your pack every time you want a snack.
