Want to ensure your feet stay warm when you ski? Start them off toasty and comfortable with the Transpack Heated Pro Boot Bag. This bag turns up the temperature on cold boots, ensuring they're cozy when you stick your feet in. The heat also keeps the plastic pliable, making it easier to get your boots on. You can use the Transpack Heated Boot Bag in your hotel, or, even better, in the car on the way to the mountain. There's also room for other spare gear like your helmet, gloves, and layers.
