Review on Nalgene Easy Sipper: Optimized For 32 Oz Wide Mouth Bottle by Katie Bobzien

Before I lost my old Nalgene I would often pour absurd amounts of water on myself while trying to drink from it. This thing works perfectly! It looks really tiny when you receive it but I promise it fits right in the opening and creates a tight enough seal to where it doesn’t fall out. It’s also easy to remove for cleaning. I would recommend not pushing it down too far, just let it hang at the top! It fits in my 48oz Nalgene as well.
