Extremely comfortable and good in a wide range of temperatures. I find it runs a little big for a Mammut. Normally a large is kinda tight, this is not, it is roomy yet still close fitting. I also bought a medium which looks better and still isn't too snug... I just don't wear another layer underneath. All in all well worth buying
