Nothing special, I realised ages ago that bike specific clothing is a bit hit and miss, I had an expensive Altura rain jacket that was coming apart after just a few uses, a Merino top from Aldi that was never comfortable and shrank in the wash, padded shorts that were impractical.
So these days I'll just wear a pair of pyjamas underneath some loose fitting combat trousers if it's really cold. My trusty Dr Marten's which I've waxed a few times so they are totally waterproof, pair of ten quid gloves, and a woolly hat!
I did pay quite a bit for a Helly Hansen Moto Jacket, but it has been great, three years old now and still going strong, very well made.
