Maplefield [3 Pack] Silicone Mouth Splash Guards Fits Nalgene Wide Mouth Water Bottles - Spill-Free Accessory - Water Bottle Splash Guard

I use them EVERY. SINGLE. DAY. Super easy to clean by just putting them in the dishwasher, very durable and have survived about 100 cycles on super-heavy-duty-extra-hot. Doesn't move or shift in any way. I sometimes use mine with a silicone re-usable straw, keeps the straw from moving around when I pick it up. 10/10 recommend for Nalgene and Simple Modern water bottle users.

Was off put paying 1/3 of the cost of a Nalgene for each insert, but can’t recommend it more after having done it. Makes drinking in a vehicle or while walking much easier without spills and holds back the ice from pouring out.

There really isn’t anything wrong with these other than a slight rubbery flavor. I have found though that it’s rather difficult to ensure I drink from the exact same spot every time and sometimes still splash myself. Almost need some kind of handle that doesn’t spin around the bottle to ensure I open it at the right spot to drink while one of these are in it.

This is pretty cool! I don’t like the way water splashes my face with this wide mouth opening. Problem solved with this insert. Ice doesn’t come out at me either. Perfect solution.

Fits large Nalgenes well.

This hits my Nalgene bottle nicely but is just a bit too small for some of my other bottles

I had to rotate it from the initial install. It fits very snugly, almost too exact-like just a micrometer too big. Didn't seem to leak where it touches. What impresses me is no more glug glug glug. It took a bit to not spill, learning curve. So, your first few pours expect a spill. After that you will catch on and not spill and not have that air causing splashes. I am very happy.I put it in the rectangle wide mouth jug and keep it there. I freeze water half full and laying at an angle. I then fill with water and bring it to work to refill my water bottle. With practice I no longer spill at all. I just keep the thing in the neck as it is ONLY water. If you use any other drink it is easy to remove to wash and no major challenges in it's shape for cleaning.

I had to pick up a few new nalgene bottles, and ordered these honestly because they were in a three pack. I honestly like them much better than the different style/ brand I've been using for years now. They fit well and the three hole side works great as a vent or to drink from. Bravo.

Good add on to the wide mouth Nalgene bottle. Need to retract my previous review on this item. When you open the packaging the splash guards look way to small, but they actually fit perfectly. Needed to actually try them in the bottle and was shocked they fit. My apologies for not trying them first. Can’t wait to put them to use on my next outing.
