When you want enough room for all your safety equipment, a lunch, and a puffy, grab the Mammut Nirvana Pro 35 Pack. Its 35 liter capacity can handle your equipment plus some extras, and the U Frame suspension system transfers your load for unbelievable comfort while you trek over those snowy slopes. A two layer EVA back padding also delivers comfort, and Mammut added a laminated stretch fabric to shed snow off your back in blizzards. You can access the main compartment from both the front and back of this pack, making it quick and easy to get snacks even with a snowboard strapped on. Both side or diagonal ski carry options give you the versatility you love. The Nirvana Pro features a waist belt you can remove if you don't need the extra support. Stuff your avy gear in the front pocket to leave room in the main compartment for your lunch, jacket, and electronics. Its hydration system includes an insulated tube cover so your water doesn't freeze out there. The pack also carries both your helmet and goggles when you don't need them, and the pocket at the waist gives a good spot for sunscreen, lip balm, and a camera. You're ready for any winter adventure heading your way this season with straps for ice axes and trekking poles and gear loops at the waist.
