Superior Wilderness Movement Internal Frame

Sold Out

 Superior Wilderness Designs "Movement" Internal Frame backpacks

Light, minimal and modular without forgoing a solid feature set and unbeatable load carrying ability for its weight. The Movement is a monster of a pack in an ultralight package. 

This pack is an awesome option for modern day ultralight trips as it is very light for a fully framed pack, but can easily be pushed up to the 35-40lb load range and still be comfortable. This is due to the single aluminum stay and the floating hip belt which is connected directly to the bottom of the stay and to the sides of the backpack. This provides excellent load transfer to your hips. 

This pack would be a great option for an ultralight thru-hike where your pack will often be around 20-30lbs or less, but will sometimes need to carry a lot of water weight or extra gear for colder temps and snowy mountains. You will also appreciate the hip belt and the frame when heading out of town with a backpack full of food from your last resupply.  If you're sick of sore shoulders, give this thing a try.

When your pack is light, you can remove the hip belt and the frame and go totally frameless without any leftover hardware or weight added onto the pack. 

In addition to modularity built into the suspension and frame setup, the other features built into the pack are very modular as well. The pack comes with three attachment points on the top of the pack so that you can use either a single top strap, a Y strap, or two single top straps which is great for carrying a bear canister. You can swap out the top strap of your choice depending on the trip you are going on, or just insert the .4oz roll top stiffeners and forgo the top strap all together for the ultimate simplistic UL top closure. 

The side compression on this pack is also extremely modular. There are 4 attachment points on each side of the pack as well as two on the bottom of the pack. You can attach the side compression straps to any of these points on the pack or remove them altogether. Cord can also be ran through these attachment points if you prefer to have static or  stretchy shock cord for your side compression.

The side compression straps can also be used as bottom straps, top straps, or even load lifters on the shoulder straps. The modularity of this setup is excellent for dialing in your perfect setup even while you are out on the trail. These attachment points on the top, bottom and sides of the pack are great for lashing things to the pack. You can lash anything from a sleeping pad or bear canister, to snowshoes or skis, and adjust exactly where you want the straps by using the various attachment points. 

This pack is also a great option if you are curious about trying to go frameless or without hip belt as the frame and hip belt are both completely removable on this pack.
