When it gets really cold on an alpine ascent, this jacket is just what you need: The Salewa Ortles Heavy PTX/Down Jacket!
According to the Body Mapping principle, down and synthetic fiber have been worked into the fitting places. Even the waterproof Pertex-laminate has outer materials that are different amounts of abrasion resistant. Where the backpack strap presses into the body and a lot of moisture builds up (shoulder and hip area), synthetic fibers were used. This goes for the sleeve seams as well, where snow contact means that a lot of moisture builds up. Apart from the thought out material composition, the technological features of the jacket are notable. It has easily accessible hand warmer pockets, which are placed high, a zippered breast pocket and a big inside pocket. This pocked can keep accessories like a second pair of gloves or a water bottle warm. To make the climbing harness accessible for belay (as this jacket is a great wrap when ice climbing), there is a practical two-way zipper, which can be opened from the bottom. The hood is first class with insulation, a very high collar, a strengthened peak, a three dimensional hood and helmet-compatibility. To allow for gloves being worn above and under the sleeve cuffs, the adjustability here is especially high.
All in all this is a superb jacket for winter mountaineering, glacier touring and as a warm transitional jacket during touring breaks in icy weather. Still, the weight is moderate and the compression pocket already integrated. Put a stop to freezing with the Salewa Ortles Heavy PTX/Down Jacket!
