Know before you buy
Yes, the pack is designed with welded seams and a DrySeal roll-top closure to provide complete waterproof protection, even during brief submersions.
Removing the harness is useful when you need to lash the pack securely inside a canoe, raft, or vehicle, or if you are checking the bag as luggage and want to prevent the straps from snagging.
The light-colored interior is specifically designed to increase visibility, making it much easier to locate smaller items at the bottom of the deep, high-capacity main compartment.
No, the compression straps are specifically included on the larger volume models to help stabilize the load and keep your gear from shifting during transport.
The pack features a padded suspension system designed for carrying comfort, though it is a traditional dry bag style without a structured frame. It is well-suited for portaging, but keep in mind that weight distribution depends on how you pack your gear.
The primary difference is total storage capacity, which dictates how much gear you can carry for trips ranging from day outings to multi-week expeditions. The 115L is significantly larger and includes compression straps to manage the bulk of a heavy load.
