Checking out what you fellas are using for hydration packs. Could have used one like a small travel pack in Mexico last week, been thinking about two options, The Ogio Dakar 3l or the Geigerrig Rig 650. The only reason I dig the Geigerrig is the pressurized delivery, I am a gadget head. I like that concept but the Ogio pack is super slick. Any other recommendations?
