What I was looking for: Slim fit, light interlining, compressible. That's what I got. The jacket is up at the top is closed, it forms a draft-free completion of the neck by the incorporated elastic collar edge. Thus, tight seal and minimum heat loss in windy conditions. The pack size (stowed in one of the side pockets) may be smaller. However, since the bags must have an acceptable size for maps, this pack size is thus by design. Those who want smaller can indeed treat from the rich Amazon portfolio of travel accessories a little pocket. The jacket dries super fast! Conclusion: Super Lightweight jacket with small pack size for the walk / climb with sufficient heat output and backpack suitability. Great quality of the Salewa has its price.
