Tried it for the first time today, 5 degrees out, no rain, jacket was perfect, had a base layer vest and long sleeve Jersey and I wasn't too hot at all, didn't even need to open pit zips, fit is perfect for me, not too short in the arms, was able to fit my hip pack under the fabric, fit wise I would say its comfortable with room to move about, not been able to test the waterproofness yet but if its as good as the rest then I will be very impressed, jacket actually looks too good to use on bike...
