Rapha, nice but a bit pricey?

Worth noting the nano treatment (stuff that makes water bead off trousers) eventually washes after numerous laundering cycles. I know their 3XDRY treatment has a short life cycle

'The protective function of NanoSphere® is still retained after frequent use and numerous washing cycles and has no effect on clothing comfort, look, feel, breath ability or elasticity.'

I think this is the same coating being used on legwarmers etc by Castelli.

At £20 a pair I'll be more than happy if I get a year out of them.
