Hyperlite Mountain Gear NorthRim 55 Pack

Built on the design of the Windrider and Southwest packs, the NorthRim increases durability with a 375-Denier fully-woven Dyneema® Composite Fabric (DCHW) built into high abrasion areas – the bottom/rand, three external pockets, and hip-belt pockets – and utilizes 3/4” nylon webbing for the body compression straps, ax loop, and grab loop. The NorthRim brings long-lasting toughness to any off-trail adventure.

The Northrim comes in the 3400 (55L) and the 4400 volume size (70L). They are ideal for routes where resupply points are far apart if they exist at all. For climbing equipment, bulkier clothing, days or weeks of water and food, or a packraft, the 4400 has the volume to get you out and safely back.

Note that due to the dimensions of this pack, we cannot offer free shipping.
