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.
