I've put this jacket through its paces and I am happy with the performance. It breathes very well. Material is very stretchy. It does have a fleece interior that adds some warmth. Works great as a touring or hiking jacket. It does let some wind through (not windproof), but that works well for me because sweat is evaporated quickly. It is a true softshell (no membrane of any kind). Repels light rain/snow, but does wet out after prolonged rain. Bottom line, does what I want it to do in a softshell.
