These are worn by over 50,000 law enforcement officers and military personnel.

We use the same material used on burn patients, so they breathe very well. They have a nonskid pad on the back where the gun is carried so they don't slide. They will fit any size pistol, including a Desert Eagle. You forget you're wearing it. It's the most comfortable and the most concealed holster on the market. Wear it under your shirt, next to your skin. The gun is placed under the arm in a cross draw configuration (A right hand holster has places the gun under your left arm). It has space provided for an extra magazine.
