Joshua’s Review:

Lightweight, functional and ergonomic.

This backpack is the perfect tool for those days where trail running meets alpinism. When it’s cold in the morning, there’s hard snow on the ground and you need to use crampons and axes, but it will be warm at the descent and you try to get out of the mountains as soon as possible.  It allows enough space in the main compartment for the cold mornings clothes, climbing equipment and food. At the same time, enough compartments on the shoulder straps for items we need along the way. The boa system combined with the ergonomic design of the backpack made it very comfortable. Despite the weight, it still looks like new after a full season on the mountains. It‘ll definitely last several seasons. No doubt the Trilogy is a great tool for multi-sport mountain adventures.
