Love these! I have poor circulation in my right arm due to previous injuries, which results in painfully cold hands indoors and out, winter and summer. These armwarmers are made of quality wool and are long enough to cover the palms of my hands, my wrists, and my forearms while allowing freedom of movement in my fingers, which is very important since I spend long hours typing on the computer. The thumb hole keeps everything in place so I don't have to keep adjusting them.
