As the name suggests, these things are the slimmest and most comfortable yet super protective pads to avoid hip and bum injuries. The SLEEPER’s base is made of super-soft, flexible and comfortable moisture-wicking Lycra material. Six neoprene covered side panels with built-in SlimShieldTM foam inserts take care of the impact protection of the thighs along with three neoprene covered rear panels with the same inserts. The slim and lightweight design has been crafted to offer maximum movement - no restrictions at all. Machine washable with no need to remove foam inserts.
