HydraPakWatergate Wide Mouth Splash Guard - BPA & PVC Free - Fits Most Wide Mouth Bottles

If this is going in a wide mouth Nalgene bottle, this is the one. I love the red color, it looks really good with the blue bottle. Made from a stiff silicone material, BPA and PVC free. It fits tight and doesn't fall into the bottle or pop out. Easy to remove to clean with dish soap. Also fit well in my no brand wide mouth bottles. It is a little bit small for a Hydroflask. It might move around a little bit and when you screw on the Hydroflask lid it pushes it down, but not all the way into the bottle (see photo). I will probably just use straw lids on my Hydroflasks and this is great for everything else.

I've been using the Nalgene spout thing (triangular opening) beforehand with a 32-ounce wide opening Nalgene bottle, but switched to a smaller bottle (non-Nalgene) for a year because the spout was not optimal. The smaller bottle meant more refills throughout the day, so I wanted to start using the Nalgene again. Strangely enough, I searched ways to make using the bigger bottle more appealing. Enter this product.It addresses the concern of having a good flow (and less bubbling spills) by having the holes to let the air in (the Nalgene did not have this). It's flexible (Nalgene is not) and soft, yet very durable. Best part is that after washing it (ridiculously easy to clean, BTW) and using it the first time there are no weird smells or tastes and the fit is optimal. I bought 2 because the price is fair, and doubt I'll be using the second one for quite some time. Plus, it actually looks cool. This product does exactly what's intended, so very happy with this purchase.

This not just prevents splashes from the nalgene, but it makes it a really great drinking experience compared to a wide mouth bottle or even a "chug cap" bottle. The drinking spout is perfectly shaped and the holes in the back allow airflow, which makes for excellent sipping, chugging, and pouring. It stays put too - you can shake your full nalgene as hard as you can and it won't fall into the bottle.I haven't tried the official nalgene splash guard product but it doesn't have the spout or air inlet holes that this one offers, so I doubt it works as well. Plus this one is silicone so it's easy to clean and unbreakable.

Comfortable without any sharp edges. Easy to pop in or out but also doesn’t fall into the bottle ever. Other caps engrave their logo into the cap and it makes it a hotbed for mold to start growing - this one doesn’t have that so it doesn’t get dirty quickly and when it does, it’s really easy to clean.

It works great. As long as you don’t push on it…. It can come out of place easily and sink to the bottom. Resulting in pouring out your water to get it out and back in place. If it could float it’d be pretty easy to fish it out.

It does exactly what you expect, it's very durable, easy to clean, and affordable.

The media could not be loaded.  I bought this and was a bit concerned when I first opened the box, I didn't think it was going to be big enough, it's fine though. I don't have any problems with the lid closing all the way. The guard keeps ice from sneaking past and choking me (as long as I use the dot hole side and not the more open side). It doesn't slip into my drink. I regularly shake my drink bottle and never have issues with the guard shifting.

bought this for my Nalgene 32oz water bottle, it fits perfect. If you are trying to buy this for their 16oz bottle, just know that it won't fit. The 16oz opening is slightly smaller so it doesn't fit. I like that this splash guard is silicone. I've had no issues with it since buying it and it really works great!

Parfait pour nalgene

O produto serviu em minha garrafa nalgene, fique com receio de não servir, mas encaixou certinho em minha garrafa.

It seemed too small initially but fits great and seals well when exposed to water. Easy to drink from and can still use the lid. Smelled weird at first but a quick soak in vinegar and water permanently solved it. No more water pouring down my face when I try and keep hydrated during long zoom calls!

Es muy buen producto, embona perfecto en botellas NALGENE y GSI pero en la KLEAN KANTEEN de 40oz de boca ancha se va hasta el fondo, le queda chica!

Works perfect. Highly recommend. Every Nalgene bottle should have one!
