For multi-day backpacking trips or your next climb up Mt. Hood the Arcteryx Bora 65 Backpack was designed for those extra-long weekend adventures in the backcountry when you need more gear than a simple over-night but don't want to haul an expedition size pack. With interchangeable thermoformed shoulder straps and pivoting waistbelt you can get a customized fit that will provide distinctive on-trail comfort. Arcteryx built the Bora 65 for comfort and used only the toughest materials for durability and strength and while their backpacks may be a bit heavier that some ultralight bags on the market you will be more comfortable carrying a heavy load with the support suspension and load transfer of an Arcteryx Bora pack.
