Bakerman,
Rukka every time, chech out this distrubutors 01425 620580 as they are always bringing out new stuff.
At the NEC show, there distrubtor showed me a new two piece suit, made from a parifin type material,
The idear is that, it cools you down when your hot,and warms you when cold..............bollocks thought I, but sweating like a pig, I put the jacket on, and within a few minutes I was comfortable.....amazing.
The catch is that it coats about £1700, certainly if I did much winter riding I'd have one.
Hope it helps,
Andrew.
Nothing to do with the company, although I know the boss.
