CamelBak H.A.W.G. ($100):
CamelBak wrote the book on backpackable hands-free hydration, so it's not altogether surprising that the standard for knobby-riding hydro packs is the H.A.W.G. Able to comfortably tote 100 liquid ounces (or three liters) of replenishment, the new, improved H.A.W.G. goes beyond the hydration essentials with 794 cubic inches of cargo volume and an exterior bungee system for added carry-on capacity. For comfort and support, the H.A.W.G. doesn't feel like a porker thanks to independent adjustable suspension straps and an Air Director back panel with special ventilation padding that make for a balanced, cool fit. You organization freaks take note: a number of storage spaces, pockets, and a mesh overflow pocket will give you all the gadget and gizmo compartments you'll need. And when you're running lean and mean, the H.A.W.G.'s dual side compression straps pull tight to cozy up like your first love. Contact 800-767-8725, www.camelbak.com.
