The jacket will keep you warm and leaves no wind through, the substance acts nevertheless very breathable. However, it has opened up from the beginning a drawback: unfortunately the zipper pulls too often with a cloth and clamped. Relatively quickly, the jacket was no longer close properly and the staples tore up. The reason for this is probably the slider which widened again and the side parts could no longer close. Unfortunately, this was despite only normal use at two copies. So the jacket does not fulfill its envisaged purpose and can get from me a maximum of two stars that only because the other processing but is well and the fabric is very comfortable to wear.
