Howard H.wrote a question about CamelBak Big Bite Valve Mouthpiece on August 29, 2013
Can this mouthpiece fit the Nathan Sports Intensity race vest? I am reading differing tubing diameters online...it appears that my Nathan tubing is 10 mm OD (eyeing it w/ a ruler)...but I've read CamelBak's tubing is smaller. Can you verify that this mouthpiece will fit 10 mm OD tubing? And has anyone successfully used this on a Nathan Sports race vest?
