Know before you buy
The Plus Size version is designed with extended shoulder straps and hipbelt lengths to accommodate a wider range of body types. Additionally, the fit geometry is adjusted to ensure the suspension system sits correctly on the body for better weight distribution and comfort.
The FreeFloat 360 system uses a perimeter wire frame with a fiberglass cross-stay to maintain structure while allowing the hipbelt and shoulder straps to pivot independently. This means the pack moves with your body rather than fighting against it, which helps stabilize loads up to the 45-pound maximum capacity.
Yes. The pack features a U-zip side access panel that lets you reach items in the main compartment without digging from the top. It also includes a dedicated bottom compartment specifically for your sleeping bag.
The FreeFloat 360 backpanel is made from a moisture-wicking, ventilated mesh that sits slightly off your back to promote airflow. It also includes an odor-control treatment, which helps keep the fabric fresh during long, sweaty treks.
The shoulder straps are attached to the suspension system in a way that allows them to pivot as you walk. This prevents the straps from digging into your collarbone or chest when you reach for a trekking pole or navigate uneven terrain.
With a 65-liter capacity, this pack is sized perfectly for multi-day trips or week-long excursions. It provides enough volume for a tent, sleeping system, and several days of food and clothing, provided you pack efficiently.
