The Crux AK47 Climbing Rucksack

Absolutely nothing superfluous adorns the Crux AK47; it is a rock solid alpine pack, stripped to the bare minimum and built from premium materials. Actually this isn't minimalism, it's more like brutalism.

The Crux AK47 is large enough yet light enough for multi-day epics. The fabric contains 40% Kevlar, making it incredibly durable, and all the seams are welded making the bag highly water-resistant. Of course, water will still get in through the top of the bag, but just not through the sides.

Structure and back support is provided by a malleable titanium frame - this is removable if you want to trim the weight right down for climbing, but it does make the AK47 more comfortable if you have a long walk with a heavy load. A massive haul loop is easy to grab onto and clip in. Apparently, this rucksack is so strong you can even stand in it while it's clipped to the belay, a feature that hopefully you won't need to use, but it's good to know you have that option!
