Assuming you would like an in-depth explanation of the product:
The Winter Secret Pro Heated Vest is a battery powered heated vest that can be worn under or over your clothing. It has three different heat settings and two zippered pockets. The vest is made of a water resistant and breathable fabric, and is machine washable. It comes in black or grey, and sizes small to extra large.
The vest uses thin, flexible heating elements that evenly distribute heat across the front and back of the body. The heating elements are located in the chest and lower back areas. They are controlled by a simple on/off switch, with LED indicator lights to show which heat setting you are on. The vest can be powered by either a rechargeable lithium-ion battery pack, or four AA batteries.
The Winter Secret Pro Heated Vest is a great way to stay warm in cold weather conditions. It would be perfect for anyone who works outdoors, or participates in winter sports such as skiing or snowboarding.
