Product details:

Building upon the super-proven Windrider and Southwest packs, the NorthRim ramps the durability factor up with a 375-Denier fully-woven Dyneema Composite Fabric (DCHW) built into high abrasion areas ?C the bottom/rand, three external pockets, and hip-belt pockets ?C and utilizes 3/4?? nylon webbing for the body compression straps, axe loop, and grab loop. If the description of the route includes words like off-trail, slot canyon, grate, scuff, Class 4 or 5, harness, belay, rappel, bushwhack, and packraft, the NorthRim brings forth the objection-free, unwavering toughness you need to succeed. The 3400 volume size (55L) is ideal for routes where water and resupply points are less frequent and the need for ropes and a harness, etc. are called for. When the extra volume is not in use, the 3400's top can roll down enough to make the overall size of the pack similar to the 2400, but that additional space can come in pretty handy when you need it.
