We’ve tested a huge variety of hiking backpacks from Osprey over the years, but this one is a first. This here is the Firn ski mountaineering pack, a versatile bag built for much more than meets the eye.
Made primarily as a ski-touring pack, the Firn is optimised for fast and light ‘ski-mo’ ascents. Our friends at Snow Magazine tested the Osprey Firn 18L in the Dolomites earlier this year, but over here at Outdoors Magic, we’ve been assessing it for its versatility – more specifically, its potential as an all-rounder that can be used for hillwalking and just day-to-day use. And so far, we’ve been impressed.
