No matter what situation you are in, you will have a pack ready to handle the environment. From climbing in Indian Creek to skiing in Chamonix, we have created technical designs to encourage your adventure. The core pack has 35L of capacity but can still fit in an overhead compartment on any flight. Built with the most durable waterproof fabric we could find it can be tossed around under any jet as well. Once you make it to your destination the core pack is incredibly feature rich for any season and any activity.
