Hey everyone! Just booked a 10 day trip out West. Planning on doing a lot of hiking in Montana and Wyoming, with trips to Glacier National Park, Yellowstone, and the Grand Tetons... Sounds great, except my camera bag is going to be freaking uncomfortable to lug with me the entire trip. My current bag is a Canon 100DG, which I don't even want to bother bringing. Looking for a backpack hiking/camera bag, preferably less than $150. Must be able to fit two camera bodies, plus lenses/accessories and then some (we are hiking, after all!). Anyone have a great pack that you'd recommend, or know of anything up my alley? Thanks guys!
