Wish I could have picked this up earlier this season, but, the best thing about this suit is that I could still wear it for the warm end of the season, and I have no doubts that it will keep me warm on most days midseason as well. Ever have a problem with snow goin' down the crack in your back? How about a lack of wrist gaiters on that sweet jacket you have? This guy will solve both those problems! I also have a mop of long, flowing Fabio hair that I would prefer not to restrict with a traditional ninja hood, so this eliminates that, as well as cuts off a little extra material on the bottom that is always covered by my socks anyway.
I'm a skinny 130, and about 5'11'', and got the medium, which fits me pretty well.
