The Summit Series Alpine Gloves give us the peak performance we've come to expect from The North Face's Summit Series. That performance starts with a progressive pre-curve shape-one that creates a more natural shape for our fingers-and ends with Heatseeker Eco Pro insulation, which offers excellent warmth-to-weight and packability for synthetic insulation. The Alpine Gloves also include a carabiner loop and a wrist leash to prevent accidental drops as we're tackling an alpine climb.
