Climbing single ice pitches or zipping up for a pre work crag session doesn't require a super lightweight, highly technical pack, but if you frequently find yourself on long, technical, and committing rock and ice routes where you need to have plenty of gear with you, you need a pack like the Arc'teryx Alpha FL 30. Made of water resistant ripstop nylon with fully taped seams, the FL 30 features a RollTop collar that eliminates the weight of a traditional brain design and extends to give you an additional 400 cubic inches of storage, all while remaining extremely water resistant. You'll probably be wearing it all day, so Arc'teryx made sure that the high density foam back panel provides plenty of support and is extremely comfortable, and made the shoulder straps from Hypercell foam to relieve pressure points and distribute weight evenly. Even though it's small and incredibly streamlined, the FL 30 has most of the gadgetry you'd expect to find on a fully featured mountaineering pack. Dual haul loops let you drag it up behind you if you so desire, while side loops hold your ice axes and the hip belt has clip points for gloves and spare gear. There are six lash points on the front to make strapping gear on a breeze, and additional bungees to hold a spare layer securely. There's even a watertight security pocket to hold little things safely, and a reflective white interior to help you find small items. If you don't make it to the top, at least you won't be able to blame your pack.
