Just bought the new "Deuter Aircontact 55+10 backpack Spring 2010" for my climb this coming 3rd week of February. This model was designed to carry big loads without blowing out your back., and also installed a lot of pockets on top, side and bottom for easy access to help you get your gears. A very organized gear storage all in one package. The Aircontact System sits even more comfortable on the back at the same time optimizing the air flow.

I'm a little bit excited on our climb 2 weeks from now, getting ready to fix my gears and most importantly this new Deuter pack that I'll be using.
