A base layer for their modular HEAT3 glove system, the Heat Company Polartec Glove Liner is made from synthetic Polartec Power Stretch PRO fabric with a highly-elastic, four-way stretch to conform to your hand. It is breathable to help reduce sweat and will wick moisture away from your skin. Designed for use under their heavier gloves and mittens, these liners can also be worn alone and are therefore made to be abrasion resistant. Even when wet, insulation properties keep the wind away and protect your hands and fingers from the cold. On really cold days, a pocket on the back of each glove holds disposable handwarmers, or can be used to stow cash, credit cards, or your ID for safe keeping. For added usability, the thumb, fore, and middle fingers have capacitive material on the tips, so you can use the touchscreen on your phone, camera, or sports watch. A D-ring on each glove allows you to connect it to your over-layer to make them easier to wear.
To find your size, measure the circumference of your palm at the widest point, just below your fingers. This size 12 glove equates to a hand circumference of 10.4-11.1".
