This has to be one of the raddest things EVER! I got it for free 2 seasons ago and it is still going strong. The pattered part that sticks out is waterproofed so my butt is NEVER wet, even when falling in the park. It also keeps snow from getting down my pants or up my back. I snowboard and kiteboard in this almost every day that I go. I have probably put 100-150 days on in this. It is awesome. def going to invest in one this year. The one I have now is in a large which fits my hips good, but it is really bagging in the chest area. Ahhh get it...you will not regret it for a moment at all! they changed it a bit from when I got mine, the fleece goes all the way down the arm, with a nylon gater, instead of before where it has nylon from the elbow down...that would make my arm a little cold sometimes.
