We all have special layers that we bought for the price of gold, from major outdoor brands, made form merino wool or super technical threads. And when I say price of gold, I am sometimes even under what you are paying for to stay warm. What about if salvation came from the East? Japan is not a warm country , not in the Northern islands anyway, so when it comes to keep a body warm they know what they are talking about. And they like style, they like to drees up with a special je ne sais quoi which makes their gear special. So if you want to stay warm and still have some $ to spend in other things, we strongly recommend you consider the Heattech gear from Uniqlo. They are awesome. Remember that they usually fit smaller than US sizes… We like the Darth Vador one very much! We really like the Darth Vader one!
