The Alta Sky 45D is a dynamic backpack that sets a new standard for adaptable carrying and working solutions. It offers versatility combined with reliable gear protection like never before! Featuring innovative 1/3-2/3 division the larger compartment can be fully accessed from the rear, quickly reached from the side, or separately opened from the top, while the smaller compartment enjoys quick individual opening from the bottom front. The multitude of Dividers and access points leave you the choice of just how much professional gear and how much personal gear to carry. Maximum capacity can fit up to a Pro DSLR with attached lens (up to 70-200mm f/2.8), 2-3 lenses, a flash, and accessories in the top 2/3 compartment and a CSC (compact system camera) with additional lens in the bottom 1/3 compartment.
