Designed for 4000-meter peaks, ready for use in all freezing altitudes and harsh mountain conditions. The weatherproof down jacket delivers ultimate Mammut cold protection in its featherweight, compressible form. This is made possible thanks to the durable recycled nylon exterior with its 850 cuin fill power derived from responsibly sourced hydrophobic down that insulates even in wet conditions. The backpack- and harness-compatible pockets can be used for your essentials when you´re touring or belaying, and you can even stow the jacket inside itself if you need a warmth backup.Performance:- These scores indicate how a product performs within its category, with each product being manufactured to the highest quality. Warmth:- Down, synthetic fibers, wool - they are all tasked with storing heat and protecting against cold. The warming layer can vary in weight, breathability and packability. Exactly how warm depends on the intensity of the sport, the outside temperature and the space in your pack.Windproofing:- Windproof clothing keeps you from getting cold on breezy peaks or blustery trails and minimizes the wind chill effect, which is your body´s heat loss accelerated by wind. Pay special attention to this factor when your pace is high and conditions are cool and windy.Warmth-to-weight ratio:- Even when every gram counts on the trail, you need clothing that provides reliable warmth. A high warmth-to-weight ratio means lots of warmth with little weight.Stretchability:- Outdoor clothing must not be constricting. It must be elastic without losing its shape and should give you maximum freedom of movement. The more flexibility your activity requires, the more important stretchy material is.Durability:- For your garment to last you a long time despite plenty of abrasion or rock contact, it has to be hard-wearing. Do you weigh every gram and define absolute freedom of movement as the most important characteristic. Then less abrasion-resistant, lighter clothing can be an advantage.Packability:- On multi-day adventures or other activities with a lot of equipment, space in the backpack is at a premium. Similarly, for those aiming to travel fast and light, packability is essential. This factor may be less relevant if protection and durability are the top priorities.Features:- Climbing helmet-compatible hood- 1-point adjustable hood- YKK Vislon® 2-way zipper for smooth operation- 2 climbing harness-compatible side pockets with zippers- Jacket can be stowed in side pocket- 2 internal Power mesh pockets- Zippered inner pocket- Pre-shaped cuffs- Adjustable hem- 850 fill power Dry Down insulation (155g) with hydrophobic finishSpecifications:- Denier (main material): 10Dx10D- Weight: 389 g- Fill power: Mammut Down 850 cuinMaterials:- Filling: 90% White goose down, 10% White goose feather- Filling 2: 100% Polyester- Insert: 100% Polyamide- Lining: 100% Polyamide- Main material: 100% Polyamide (recycled)- Fill weight (down): 155.00 gPerformance:- Warmth: 6/6-...
