hi, I have one and been using it for about a year now.
It is very waterproof and is pretty breathable as well.
It has no signs of wear from shoulder straps (I ride to work in it with a backpack, off-road with a Camelbak), the fabric is pretty robust, it is lightweight too and stretchy in places, tho if you ride somewhere with lots of snagging trees/brambles/bushes that type of thing then I guess like all lightweight fabrics it will potentially tear.
I have fallen off a couple of times and nothing bad has happened other than it getting dirty.
It’s a great shell, rolls up small, fits well and stretches in the right places, as people have said above it is just that tho, it is not warm, it is waterproof and windproof but definitely not warm.
It also does not come with a hood, you can buy one separately, so water will ingress down the neck if it is totally p*ssing down, but to be honest a hood will not be that much help then anyway.
the rest of it will be dry tho.
It is expensive but it is a good cycling jacket and I use mine a lot so have had my moneys worth out of it.
plenty of reflectives on it as well so good enough for a commuting jacket as well as an mtb one, so only need one jacket for both.
wish they had done it in the green when I bought mine, was only black or red last year.
