This is a more minimalist pack with features for alpine climbers and mountaineers and yet still an excellent option for backpackers and trekkers looking to shed a little weight. We were surprised by how comfortable this pack is considering its low weight (often light packs sacrifice comfortable suspension). A big way the South Col saves so much weight and tips the scales at a mere 3 lbs. 14 oz. is because it doesn't have a ton of features. You won't find a lot of pockets for organization or bells and whistles here. Despite its light weight, the pack is durable. After 20 days of hard use, it still looked great and we expect it to be one of the most durable packs for its weight. Items:-Double lid thing — some people will like it while others will think it's stupid.
-Trim cut makes it more suitable for mountaineering and Alpine climbing.
-Not lots of pockets.
-Very light for its size and toughness.
