Comfort/Fit 
The Peak 45’s rigid, sweat-wicking back panel and cushy hip straps provide plenty of comfort and support under a heavy load. The pack skied great and also has adequately padded shoulder straps.  

Ski/Snowboard Carry 
The Peak 45 is capable of both carry options. A-frame carry comes standard and the diagonal carry utilizes a thick tail loop and metal hook and attachment point up top that can double as a rope strap. It will also carry a snowboard. 

Features 
The most interesting feature of the Peak 45 is the side access zip, which runs from the right shoulder all the way around the bottom of the pack to the left hip. This allows for the entire pack to be folded open from the outside. One flaw is the top of the zipper runs underneath the lid, so it must be unclasped in order to open and close the side zip. A dedicated avy pocket, axe attachment, helmet carry, and hip belt pocket round out the feature set. Note that the Peak 45 lacks an insulated hydration sleeve. 

Ease of Use 
The Peak 45’s waist belt adjusts from the hips by pulling straps inwards towards the belly button, which made for an easy and secure adjustment method. The straps and zippers are straightforward and easy to use. 

Durability 
It’s clear the Peak 45 sacrifices on strap (particularly the A-frame carry straps), and fabric thickness to save on weight. However no specific issues were noted during testing.
