The AK37 is a compact climbing sac for mountaineering and alpine rock routes. A traditional top-loader, it has quickly gained recognition as an excellent all-round sac, particularly on big one-day technical routes. Uniquely for a sac this size, it has a frame making it comfortable to carry even when laden with 10 kg of ropes and hardware.
