Lightweight and versatile, the MYSTERY RANCH Scree 33L Backpack lets us tackle everything from hiking to climbing and mountaineering. The 33-liter capacity can carry our cold weather gear or climbing gear for a day trip while the pack's aluminum frame helps transfer the load to our hips. The pack also features plenty of gear loops and external straps to attach additional gear, such as our poles or ice axe. On the flip side, gram counters can also cut weight by removing the hip belt or frame or both for ultralight missions in the mountains or snow. That versatility makes this a nice, multi-sport pack for all season outdoor play.
