You get out in all of them, and the anytime, any-terrain Millet Peuterey Integrale 45+ 10 Backpack will carry your crampons, ice axe, skis, and rope, in addition to your down booties or whatever else you deem indispensable. That inclusive load sits comfortably on the Free Flex System, giving you a smooth ride no matter the season. Zippered pockets, including a dedicated crampon pocket, make sure that all your gear is organized efficiently and easily accessible. When the pack's not fully loaded, side and top compression straps serve to cinch down your load quite nicely. With all this comfort and capacity, you might be tempted to watch the season change from the mountaintop.
