Review on 🚰 4-Pack Bite Valve Replacement Mouthpiece Cover for Hydration Pack Bladder - Compatible with Most Brands by Patrick Diaz

The tubing is a bit stiffer than the flexible material that comes with a decent camera. The inner diameter of the hose and the notch size of the check valve are slightly larger than the Platypus Hoser, but the flexible Platypus hose fits at least three notches. I haven't tried the bite valve. I used a check valve on the line before the quick connect so I have some sort of faucet at camp and to prevent spillage when I'm quickly filling my bladder in my backpack. I used a Sawyer quick fill kit and had to put rubber bands around the hose so it would seal the smaller Sawyer barbs. I had to file down the downstream side of the check valve to fit a hose over it to use it in line. But I am not using it for its intended purpose. If I understood the size difference and that check valves only have serrations on one side, I would get something more appropriate for my application. For its intended purpose, this is a good product for the price. (I got it "used" and saved a few bucks more.)
