I ordered the warm version, and although it fit perfectly in other places, it didn't fit my arms properly. I contacted the seller who was extremely accommodating, and he helped me out to exchange it for the normal version, which is supposed to be stretchier. I can't wait to get my exchange in the mail, which should be this week. Shipping is so fast considering it's coming all the way from Bulgaria! I'm supper impressed with everything about this business as well as the quality of their products....
