I was in heavy rain at 71* f with about 60% humidity and it did keep dry from the rain but not from all the sweat inside. It didn't breathe any better than the Castillo IDRO rain jacket. I think all of these rain jackets are built for cooler temps where your in rain but won't sweat as much. I love the orange color where the Castillo is black. Not as tuckable or compact as the IDRO but all being said, if the IDRO was brighter color I'd stick with that
I use this for the rain and as a outer shell that will need to be shedded going from cold to warm. It folds up nice to get in back jersey pocket. I am 5'7 and 145 pounds and the medium was just too tight. The large fits perfect for about any layer underneath. BTD had an unbelievable price on these where I couldn't pass it up
Overall a really nice jacket. Tye zipper is easy to use. The collar fits well and its going to keep rain out.
The pocket access isn't fantastic...my only gripe.
The reflective rear strip is better than expected.
