OXA Blue Hydration Pack, $21 with code NQQFHBM3 | OXA Orange Hydration Pack, $31 with code OBOAGZL2

Before you head out on your next hike, be sure to pick up one of these affordable hydration packs. Both come with the same 2L water bladder, but the more expensive model has a larger backpack. These are some of the best prices we’ve ever seen on any of these things, so pick this one up before the deal runs dry.
