It's waterproof yet breathable and lightweight, no sticky, sweaty sleeves! Perfect for running and sweating.. Buy a size larger than you think. Also, the jacket does leak a tiny bit along the zipper line, but no where else (!) thankfully.

Incredibly light weight, completely waterproof. Relatively quiet when running.. However, it doesn't take much for my body to heat up while exercising. While it is breathable I did start to get sweaty by the end of a long arduous run! But I don't think there has been a jacket that has been invented that will stop this in my case!!

Super-lightweight. Good long coverage, well below waist. Not cheap, but compares very well against other similar items and has good "stats" re. waterproof quality.. Nothing

Incredibly light and packs away to size of orange. Just what is needed when traveling light. Very good breathability and has kept the rain out so far. No although a little on the expensive side I think
