i bought some of these a the bike show last week and went out yesterday to try them out.

they are a very thin material that rolls up into a tiny bag for carrying about (ideal for my trip to majorca next week ) and don't look like they'll do much. don't know what the temperature was yesteday, maybe about 12, but i had the EDZ trousers on underneath hood biker jeans and there was no draught whatsoever - plenty warm enough

on top i had the EDZ jumper over a normal t-shirt and then my arlen ness leather jacket and again it was warm enough. i was only out for an hour, so it may have been a bit cool on top after all day in the saddle and may have required a sweatshirt over top.

am very impressed with it wasn't cheap though, £70 for both jumper and trousers that seems like a lot of money for a bin bag but i will also use them for skiing
