Add an extra layer of warmth and protection for your hands and fingers with these Tactility Glove Liners from The Heat Company. Made of a thin yet warm polyester material, they retain their insulation properties even when wet, and will easily fit under many extreme-weather mittens and gloves as a base layer. The thumb, fore, and middle fingers have special material on the tips that allow you to use the touchscreen on your phone, camera, or sports watch, and the back of each liner has a pocket for additional hand warmers when the temperature really drops.

To find your correct size, measure the circumference of the palm of your hand at its widest point, just below the fingers. This size 9 glove liner equates to a hand circumference of 7.4-8.1".
