The fit and feel is incredible. Way better than others I've tried.  I use this for my work commute and while out and about. Also, lots of air travel and it has remained in shape and without runs on the material.  The elbows have remained dark without much indication of rub or material wear.  Others immediately show the wear on the elbows after only a few days of use.
I am 5-10" - 185LBS.  I wear a LG and it is plenty comfortable even when wearing shirt and warmer below.  This is a Spring/Fall type Spyder, but I wear it year round in North Alabama.  Not meant for those days below 30's or long exposure during commute or fun-play.
