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

I bought this to replace the stock bite valve on my Nathan Trail 7. The valve was well suited to replace the original valve which was leaking after 3 months. This valve now leaks even when the twist is off. A bit messed up, but summer is coming soon, so I'll probably tolerate it until it gets cold and replace it next winter. Will run some tests and later update the water loss rate during the run.
