When shopping for clothing items to keep you warm especially if you have Raynaud's or any other issue with low thyroid function or poor circulation, try the skiing area or the Sporting/ Hunting area. (last year I found the most incredible mittens 1 pair fleece at a ski shop, and 1 pair was ski waterproof mittens from Sports Authority) Those are the people who are in out in the harsh elements for extended periods and they have the best supplies for staying warm and toasty. Also don't forget some great boots like Ugg's or Minnetonka or another comfy , yet toasty warm fur lined boot. Don't forget to water proof if necessary or pick boots that are waterproof. It's been getting colder and colder here in NY....BRRRRR!
This is a link to the brand that was at Walmart.
An extra tip - if you shop at the end of the season at clearance time you can get great deals...these items are going to be more costly though.
