Organizer pockets, 75 or 50 liters of space, backpack carry so you've got your hands free.. this is designed not only to tote all the ski stuff, but to do it in a way that doesn't demand the use of color coded compression sacks so you can find what you're looking for at speed. Exterior pockets you can designate for everything from gloves to gaiters to climbing skins. An interior pocket with enough space to carry boots and then some. For the organized among us who like our gear packed up and ready to go at a moment's notice, no fumbling, no running around the house trying to figure out where the baselayers have got to, this is the bag that sits, packed and ready for the first flakes and first runs. The size of this thing, and its separated organizational pockets, also makes it a great pack for traveling with family, when knowing where the thing is makes keeping the small groms happy and the trip flowing well. A bug-out to the mountains bag with the size you need to carry all the stuff and the organization your brain requires to keep it from being a jumbled heap you have to dig through to find your helmet liner or ski socks. Get this. Pack this. Watch the weather reports. Go!
