Just got this is the mail and it's sick! Haven't riden in it yet but I can tell you that I am going to love it. I'm 6', 155 pounds and I went with the Medium. The only place that this suit is pretty much skin tight is on my calves, which is perfect since they will be going into my boots so I want them tight enough that my sock will fit over it just fine! Can't wait to ride in 9 days and test this thing out!
