It's $100+ more than the Aerostich!
I'v got a 2 piece and a 1 piece suit and they are brilliant. I've done 30k+miles in the 2 piece and over 5k miles in the 1 piece and apart from forgetting to waterproof teh side of teh zips against water ingress in serious downpour (wet inside leg) they've been fantastic.
They're also available in a range of colours and can be custom fit for odd shaped peeps like me!
