Review on Efficient Protection: Guyot Designs SplashGuard-Universal Shields Your Gear by Djkutt Kent

Received this to see how it would work with our wide mouth Nalgene bottles. I've been using it for a few weeks now and I love it. The fit was great and there were no issues with it coming out while drinking. I would have bought more for my family but mold started in one department. I used to only hand wash it along with the bottle. Once the mold started I couldn't get rid of it. As a last try I used steel wool, thinking it was on the surface of the fender. It wasn't the surface, it was the material.
