Made with a thick Polartec lining, these Heat 3 Smart Pro Mittens/Gloves from The Heat Company are designed to provide more warmth than the standard Heat 3 Smart gloves, making them suitable for even harsher conditions.

When you're out in the cold, conserve heat by using the outer mitten, and then when you need to do some work, get a drink, snap a selfie, or perform any task that requires dexterity, just fold the mitten and thumb back to expose your liner-gloved fingers. The integrated inner lining allows full use of your hands, yet still helps keep your fingers warm.

Your first layer of protection from the elements is a wind- and water-resistant mitten shell with Primaloft Gold synthetic down insulation. The back of the mitten has a zippered pocket that can hold a disposable hand warmer, your car keys, a credit card, or cash. The palm is reinforced with soft and durable goatskin, which is naturally water and wear resistant. Extra-long cuffs with drawstrings keep heat in and snow and wind out. When it's time to get to work, flaps on the fingers and thumb fold back and are held out of the way with simple magnets. Heat 3 Smart built-in glove liners are located beneath the flaps, featuring wind- and water-repellent Polartec Wind Flow fabric. Even when wet, the liner's insulation properties protect your fingertips from cold. For added usability, the thumb, fore, and middle fingers have special material on the tips that allow you to use the touchscreen on your phone, camera, and sports watch.
