Why This Set Is Perfect for You
✔ Fast, adjustable warmth: Built-in carbon fiber heating sheets warm up in about 10 seconds, with three settings from 86°F to 122°F. A single button makes it easy to choose the warmth level that suits the conditions.
✔ Heat where it matters: Heating zones at the knees, back, and waist deliver fast, even warmth across areas that can feel the cold. The targeted design helps ease discomfort and stiffness in cold conditions.
✔ Stretch for easy layering: Four-way stretch fabric supports a snug fit and free movement, whether worn on its own or as a base layer. The soft, moisture-wicking, odor-resistant polyester-spandex blend is designed for comfortable wear.
