Superior Wilderness 70L Wolverine Internal Frame

Wolverine — Ultralight Load Hauler for Big Miles

Built for hikers who demand ultralight efficiency without sacrificing carry comfort, the Wolverine pairs the proven simplicity of the Long Haul with the beefier frame and suspension of the Big Wild. The result is an ultralight pack that handles heavy food and water carries with ease, making it an excellent choice for PCT thru-hikes, long resupply stretches, packrafting sections, and desert water carries.

The Wolverine comfortably carries up to 50 lbs, yet remains trail-worthy when loads drop back into typical thru-hiking ranges. With up to 3 inches of torso adjustment per size, dialing in a precise fit—critical for long days and long seasons—is quick and straightforward.

Constructed from Ultra 400X, the pack features a UHMWPE face fabric that offers exceptional abrasion resistance while remaining impressively light. The laminated construction makes the fabric fully waterproof, keeping gear protected through snow, storms, and creek crossings without the need for a pack liner in many conditions.

Designed with thru-hikers in mind, the Wolverine keeps things simple, intuitive, and durable. Unnecessary features are stripped away, reducing weight and eliminating failure points. The pack can be run with as few as two buckles—one at the roll top and one on the hipbelt—for a clean, minimal setup, or expanded with modular compression and external straps when extra capacity is needed.

Extensive attachment points allow the pack to evolve with your hike—whether that’s adding straps for bear can carries, snow gear, or bulky food loads. When compression straps are removed, there’s no leftover hardware, preserving a sleek profile and minimal weight.

The Wolverine comes standard with a foam sit pad stored in a durable lycra back-panel sleeve made from UHMWPE-reinforced Venom Mesh. The pad adds structure while hiking and doubles as a comfortable seat for breaks—one less item to carry, one more convenience on trail.

Bottom line:
The Wolverine is built for hikers tackling big miles, big carries, and long seasons—a dialed-in ultralight pack that excels when conditions get demanding, without overcomplicating your hike.
