I have two of these, one being a 2012 version. You can read about all the features on the Klim website. Things I noticed; the new Cordura makes the pullover beefier, although I never had a problem with my old one. The zipper up the side is a nice addition, which makes it much easier to put on over a Tekvest. The pullover is cut a little bit bigger than my old one, with the arms being longer. Not a big deal with the Velcro cuffs, but I'd still prefer the sleeves shorter for me. I'm sure that taller guys will have no issue. I buy these pullovers one size larger to better clear my vest.
The quality looks great and is consistent with all of the exceptional Klim gear that I have acquired over the years. I expect it to exceed the performance of my old Powercross pullover, which still works great. I’d definitely buy one again.
