A CZone membrane protects against water and releases moisture, while G-Loft synthetic fill insulates throughout the long winter days on the mountain. The glove has outseams for better comfort and pole grip. Foam panels on the hand's upper side protect against falls and impacts. A neoprene cuff provides a better fit and keeps heat inside the glove, while also being able to glide smoothly inside the jacket sleeve. Other smart details include the wrist strap that reduces the chances of you dropping your glove, and a carabiner to connect it to your backpack. Snug by design, size up.
