Everything on this thread is a great way to keep yourself warm. Being a Raynauds sufferer in both my hands and feet, it gets very cold fast!
Spiritwalker made a very good suggestion about wearing thin cotton socks underneath a good pair of thermal socks is fantastic. I was taught to do this when I was in the Air Training Corps, they said it was an essential thing to do especially on Annual Camp. I also washed my feet before I went to bed, which worked a charm
. One of my friends suggested I should buy a pair of those battery powered heat socks, sounds a bit ludicrous, but Im curious to try them. Does anybody own a pair and willing to give a review of them?
I would also recommend a Polar Fleece Honcho. I bought one at a festival I went to last year and it has never let me down. It kept my back warm too which is a big bonus. You can buy them
here.
For base layers I wear a rash guard. I practise Brazilian Jiu Jitsu so I have both MMA and water sport rash guards. The MMA type keeps you cool whilst the water sports type keep you warm. The reason why I had to explain the different types was because I knew a friend who bought an MMA one thinking it would be a warm base layer and he was shivering soon after haha.
