Comfortable enough, although the very padded hip belt feels a little clumsy in comparison with some. Unique belt buckle is very easy to use with cold or gloved hands, but the chest strap is fiddly to adjust. Freeflow back system suspends the load nicely away from your back, but also makes it a little unstable, especially when full. The main compartment is very large, and there’s an extra five litres in the side expansion pockets and lid. Well-priced.
