In reply to yewchen:
The Dyno jacket is a comfortable stretchy jacket.
Not totally wind proof or water resistant but very comfortable to climb in on an average day.
Its quite a casual jacket. I bought one to replace my old fleece, its far more comfortable and less bulky, and does a better job. Bought mine online at Jackson Sports, is this where you were looking?
