This alpine pack is great for longer mountaineering/climbing/ski touring adventures. The harness is decently comfortable, keeping the pack close to your back. The pack is fully featured with an integrated helmet cover, glove friendly buckles, a frame ski carry. rope carry options, removable top lid, ice tool attachments and gear loops. This is not the lightest alpine pack out there, but it is durable and reliable for any alpine adventure.

This alpine pack is great for longer mountaineering/climbing/ski touring adventures. The harness is decently comfortable and carries load well, keeping the pack close to your back. The pack is fully featured with an integrated helmet cover, glove friendly buckles, a frame ski carry. rope carry options, removable top lid, ice tool attachments and gear loops. The 52L has a unique feature that allows you to remove the hip belt fully. This is helpful if you want to switch it for a more lightweight option. This is not the lightest alpine pack out there partially due to its padding which can make it feel a bit less agile, but it remains a durable and reliable pack for alpine adventures.

Fit tip:

Comfortably padded but restrains agility
