Bringing this thread back from the dead.
I finally rode with this jersey in 95F+ and not a cloud in the sky along with the 95+% humidity that came with it. 3.5 hr ride at pretty good pace for me. I was wearing a mesh baselayer (Castelli) as I did not expect the heat to be this bad. Should have checked the weather before leaving!! Phenomenal to say the least. Wicking action is awesome and yet I never felt extremely hot in it. I hardly ever unzip much, and despite the weather it felt pretty good. Certainly much better than all the other jersey types I own (Castelli, Capo, Nalini, etc.). In my mind at least, certainly worth the price. Especially when you buy it at a 15% discount from Wiggle or Ribble!!
Does it work? YES. Does it inflate to high pressures? YES. Does it take a ton of pumps? YES! The major downsides I found were that it got hot after several pumps, and that it was a bit cumbersome to hold while pumping the tire.
Got it to replace the one above. Works and it does put in high pressures at the expense of a lot of pumps. That is a common thing to all of these little pumps anyway. Certainly easier to hold while pumping than the one above.
