Know before you buy
Yes, the 45L volume is well-suited for overnight or multi-day backcountry tours where you need to carry extra layers, a sleeping system, and technical gear. If you are packing for extended expeditions requiring heavy winter camping equipment, you may find it tight, but it is ideal for hut-to-hut tours or fast-and-light overnight trips.
The SWISSWOOL 3D back panel offers a distinct advantage in temperature regulation. Unlike traditional closed-cell foam that can trap heat and moisture against your back, the wool fleece is naturally breathable and moisture-wicking, keeping you drier and more comfortable during high-output ascents.
Yes, the pack features both top and front-panel zipper access. The front-panel entry is particularly useful for reaching items stored at the bottom of the main compartment without having to unpack your entire kit.
Yes, the Peak 45L is hydration compatible, featuring an internal sleeve and routing for a hose. This allows you to stay hydrated on the move without stopping to access water bottles.
The pack is designed specifically for alpine environments and includes dedicated, reinforced attachment points for ropes, crampons, and ice axes. These are positioned to keep your technical gear stable and balanced while you are moving through challenging terrain.
Yes, there is a dedicated safety compartment designed to house your shovel and probe. This ensures your emergency equipment is isolated from your main gear and can be deployed instantly when seconds count.
