Review on Black Hydrapak Blaster BITE Valve with 1/4-Inch Inner Diameter (I.D.) by Walter Martin

Needed to replace the original Hydrapak bite valve after it seemed to have taken a stab for years; This one fits well and includes an on/off valve + dust cover. The lid can be removed, but it's great for keeping dust out for your next drink on the road. I'm not currently using the on/off valve, but it will come in handy if this valve experiences a similar leak in the future.
