Excellent quality of both materials and design. Sizing details are accurate. I tried to squeeze into a medium but had to accept that I am a large. Still a good fit with enough room for one or two thinner base layers. I would highly recommend this product.

Good light jacket that can stow away small in the included pouch. I find it useful for cooler days (~10°C) but not much colder unless very active. Haven't tried it in a downpour yet but the material and zips look very water resistant. I usually buy medium and this is a good body fitting jacket. You can't wear a lot under it. If really cold it can be used as an underlayer for the MIG jackets.
