Hi Life's Too Short - I'm a Reynaulds suffer so I can sympathise. I was diagnosed 4 years ago ( after having symptoms for years before) and prescribed Nifedipin (may have spelt that wrong!) which I take as and when I need to. I have found that it really helps ease things. In this weather I always wear two pairs of socks and a decent pair of gloves .
Liz, I have the same jacket as shown on the link in your post. Personally I am more than happy with it and feel that it keeps the worst of the wind/rain etc off whilst not making me feel too hot and sweaty.
I do prefer to wear a jacket to train in during the winter because I do feel the cold quite easily!
