These knitted belly warmer pants were created under the supervision of sleep therapist Ms. Mihashi. When your hands and feet get cold in the cold weather, it's best to warm your stomach, which is in the center of your body. These cotton-silk blend knitted belly warmer pants completely wrap around your stomach and hips, the areas you want to keep warm the most. They stretch out nicely without being constricting, and fit gently. Recommended for people who get cold in their stomach, hands, and feet.
