• Large, 3/4" diameter x 1/4" thick, 4,300 gauss magnets: for deep penetrating relief and more rapid healing. The special research grade ceramic material and larger size of these magnets, produce magnetic fields that are up to 8X more effective than the ceramic magnets used in other supports and up to 3X more effective than the smaller neodymium magnets that some supports use.
• Patented Thermal Regulation System: Whether you're an athlete, a weekend warrior, or simply relaxing at home - This amazing "Smart Support" system provides unmatched comfort and support at any level of activity. By precisely controlling the movement of heat and perspiration, it dramatically increases wearability and user tolerance from only an hour or so, as with standard neoprene supports, to 24-hrs/day for an indefinite period for Therion supports.
• Plush Inner Lining: is amazingly comfortable on the skin.
