The Quantum series is our lightest and most flexible glove we have created.  Combining a ultra light backhand with a flex points in key areas.  The new Rubber Gel Comfort Tab allows the keeper easier ability to put his gloves on as well as make small adjustments while wearing the gloves without refastening the velcro strap. The Quantum Exo series is also a very lightweight and flexible glove that features a breathable Exo-Skin backhand as well as a double elastic wrist strap for a very comfortable fit.
