This 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, as we found out when we tested the this pack in the Dolomites earlier this year. This season, our friends over at Outdoors Magic have been assessing it not just for its ski touring credentials, but also for its versatility – more specifically, its potential as an all-rounder that can be used for hillwalking and day-to-day use. So far we’ve both been impressed.

The Firn 18 is made from tough, recycled materials with bluesign approval. The back panel has foam ridges covered in a stretch woven fabric, a combination that prevents snow climbing to the pack while also helping to create airflow and cooling.
The harness resembles the same kind of design you’d expect to see on a trail running vest. Not only is it made to fit with the contours of your body, but it’s also able to move closely with you, especially when the blood’s pumping and your lungs are really working.
Osprey of course have a whole host of packs dedicated to hiking – the Talon being one of the favourites over at Outdoors Magic – but if you’re a ski mountaineer looking for a pack that doesn’t necessarily need to be stowed away once winter’s over, this would be a great option to get your hands on.
