How ThermaJock Works

ThermaJock™ is the first product of its kind designed with the specific intent to protect the penis. While developing this unique product, our first priority was to resource the best materials available to ensure a trusted quality garment a man can truly rely on.

Our approach is simple...

• Provide warmth and protection to a previously ignored region on a male
• Offer adjustability and comfort via a dual fastening system
• Protect with dependable, high-performance Polartec® Thermal Pro Fleece used by leading athletic garment companies

ThermaJock’s warmth is attributed to the use of Polartec® Thermal Pro fleece. The 100% polyester fabric’s surface creates air pockets that trap air and retain body heat, providing outstanding warmth without weight. This fabric also offers excellent breathability and dries quickly while being machine washable.

ThermaJock stays in place by using a unique double fastening system. The fasteners can be adjusted to fit any size athlete. The ability to use a cord at the top and a strap in the middle allows ThermaJock to stay in place without having to over-tighten a single fastener and sacrifice comfort.
