If your idea of fun means navigating technical rock ridges and committing ice routes, then you probably already know the Arc'teryx Alpha FL 30 Backpack. Why? It's constructed with you in mind. The minimalist style doesn't skimp on materials, employing ripstop nylon with taped seams and a DWR coating to provide an extremely water-resistant pack while weighing just under 22 ounces. Alpinists understand that excess pockets and fabric tend to get in the way, so Arc'teryx threw out the traditional floating lid in favor of a RollTop collar, cutting weight while allowing for customizable pack size. Spending an entire day climbing with a backpack can be uncomfortable, but it doesn't have to be. The Alpha FL 30 uses super comfy polyethylene foam in the back panel and cushy Hypercell foam in the shoulder straps, so you can focus on your next ice screw placement rather than be distracted about the weight on your back. Despite its diminutive size, the Alpha FL 30 still manages to cram in features typically found in much heavier packs. Dual haul loops give you the option of dragging the pack through crux pitches while side loops let you stash your ice axes during the approach and descent. The six lash points enable you to strap extra gear on with ease and the included bungee makes stowing a spare layer extremely easy. Your phone and other small gadgets will fit nicely in the watertight pocket, securely separated from the remainder of your pack's contents and easily accessible. Long mountain routes are already difficult enough--increase your odds of success by relying on the FL 30.
