We are ordering this super versatile comfortable pack for my husband because I have the smaller one already. I have loaded mine to beyond capacity & it still carries quite comfortably. The Air Contact Technology pads not only pad the back, they also air condition your back in summer and keep it warmer in winter. The ice axe and hiking pole loops keep that equipment from bonking you in the head. The front loading combined with the top loading is really convenient. It loaded up just like one of those fancy camera specific packs & made check thru TSA a breeze during a recent trip. The stretchy shovel pouch on the front will even hold a hard hat. The rain cover is well designed to fit the pack, works very well, & does not bunch up the suspension system. The hydration pocket holds a huge bag of water & a sit pad with room to spare for a balaclava, & there is a compartment under the lid for a first aid kit, handwarmers, & ace bandageDeuter is one of the oldest pack makers in the world.
