Attach the CamelBak Magnetic Tube Trap to your backpack's 3/4-inch webbing strap for an easier drinking experience with your CamelBak reservoir. Your reservoir's hose clicks into the trap's self-sealing magnets, preventing the hose from swinging around when you're hiking, trail running, and mountain biking. It features an auto-locking mechanism that prevents the hose from accidentally coming free. To release the hose from the magnetic attachment, simply slide it laterally (on a shoulder strap) or vertically (on a sternum strap).
