Been rinding with one of these for a month & am fairly pleased with mine.
Completely waterproof, very good in a downpour. Washes on 40 degrees according to the label but I've only ever done 30. I'd give breathability a 7/10.
You need a good wicking base or mid layer underneath & post ride there is a definite film of moisture on the inner of the jacket, but given the price it's pretty good. Nowhere near a goretex etc though.
