The Black Diamond Midweight Screentap Glove Liners are stretchy gloves that have a multitude of uses. Construction of the glove uses mid weight fleece on the back of the hand with nylon on the face of the glove that add durability. The palm of the glove is covered with U/R powered conductive material on the palm and the fingers for touch screen use. For extra cold days, they can be used a layering underneath your ski gloves of mittens for an added layer of warmth. And when it comes time to access your cell phone, you can leave them on and still have touchscreen functionality. When it warms up a bit, use them a spring glove for skiing, or for trial running or biking when it still cool outside. For true 3- season use, the BD Midweight Screentap Glove Liners have got your covered.
