When I purchased this I was hoping for some wind protection with it, but it is not very wind resistant. But that ended up being a good thing for me. I started wearing it ski touring and since the first day I used it it is my go to for the uphill. I get hot and this thing breathes and keeps me warm enough when moving. It is a little chilly if you got your sweat on and you stop for any length of time. I wear just a long sleeve lightweight fleece shirt underneath all winter long. I use the hood quite a bit. It would be nice if it had an elastic to pull the hood back a little as it comes down a little too low for me. I'm 6ft, 210 and the large fits me perfect. Mine is till in perfect shape after 5 years, but I keep thinking about buying another one in case they end this line.
