NorthRim 55



Focus on finding your way through the thick of things with the burly NorthRim 55 and its capacity to carry everything you need to thrive on multi-day, off trail backpacking missions. Ideal for weekend, section, or thru hikes where resupply points are less frequent and/or for equipment flexibility. When the extra volume is not in use, the top can roll down enough to make the overall size similar to a 40-liter pack.

Our preferred pack if the description of the route includes words like off-trail, slot canyon, grate, scuff, Class 4 or 5, harness, belay, rappel, bushwhack, or packraft.


Formerly known as the 3400 NorthRim. Packaging may have either name but the product is identical.
