Replace your drink tube with this enhanced set from Mazama Designs. The system includes a 39", 1/4" ID drink tube and Mazama's high flow, bite valve that can be activated from any orientation. The low-profile bite valve features a one-handed, push button shut-off with an integrated magnetic retention system for tethering the bite valve to pack strap. The magnetic strap retainer attaches to either 3/4" or 1" wide pack straps. A mid-line quick-connect allows easy removal of the bladder from a backpack. The quick-connect automatically shuts off flow from the reservoir whenever it is disconnected. Compatible with any hydration reservoirs that feature 1/4" ID drink tubes. Connect to an existing quick connect port or connect directly to a barbed exit port.
