Good product, one caveat
I have been using the Fawesome the past few weeks in temps ranging from 4 to 14 Celsius (40-57 F). I have used it in the cold wind and also in a warm-ish rain and all in between. It is quite versatile, I like it for warmer rainy days because it will keep my core mostly dry and warm but I won't overheat like I would in a rain jacket, even something breathable from eVent fabric. I can vary my base layer and jersey selection for the temp and use the Fawesome as the outer membrane.
I also have the Isterico, and it is a good product but much more thermal and a little less water resistant. If I could only choose one I would choose the Fawesome.
The fit is snug, I am 6' and 170 lbs with a 38" chest and the Large gives me a perfectly snug race fit. The only blemish is, as another reviewer points out, the arm holes are cut just a little too large and I have a bit of material flapping on the upper back part of my shoulders. I still gave it 5 stars though, just because it is so incredibly versatile.
