I've had a Gamma MX for five years or so, no hood. I wear it all the time on and off the slopes, I love this thing. With a base layer and some kind of mid layer (mostly Delta LT 1/4 Zip), the Gamma MX has taken me down into the 20s no problem. When the weather turns wet, I throw on my Sabre SV over the Gamma MX. It all keeps me warm and dry. Its a great jacket.
