The North Face's Montana Liner Glove is thin enough to disappear under the Montana 3-In-1 GTX Glove or Mitt, or any heavier shell glove already in the closet, without adding bulk to the fit. A grid-knit fleece shell made from recycled polyester keeps hands warm on its own for a chilly run or training session, and silicone gripper dots on the palm, thumb, and first two fingers hold onto trekking poles or a phone case. An Etip index finger keeps the touchscreen working without pulling the glove off. What Our Gearhead(R) Experts Are Saying:"I keep a pair of these in my jacket pocket for the first cold miles of a run, then switch to my shell glove once the wind picks up without ever feeling like I'm wearing two gloves at once."
