The Fjällräven Back jacket is very lightweight and well-designed for general fast and light hillwalking. It is made from a 2.5-layer Hydratic membrane, which is nice and thin, supple and lightweight, but does not claim to offer the breathability performance of higher-priced jackets. Also as it is a 2.5-layer fabric it feels a little clammier than the higher priced 3-layer fabrics, but you do get side vents to compensate. However the features of the jacket are good as you get a stormflap over the front zip for example to keep wind and rain out, a feature that most lightweight jackets lack. Also there is a little more length in the body than some, so again it offers better protection. The pockets are large enough for maps and they’re placed high on the body so they can be easily accessed when wearing rucksacks. The hood is pretty good too, thanks to a stiffened peak and good fit and movement, although it cannot be rolled and secured at the collar. Overall the Fjällräven Back is more of a light hiking jacket than a running jacket, but you could use it when biking and it works well as a general mixed activity jacket.
