Nalgene Easy Sipper (Red, 1-Quart), 32 oz

This sipper lid fits perfectly into my nalgene 32oz bottle, right under the outside lid. It makes it easy to drink from without spilling if I hit a bump in the road or while walking up or down hills. It is secure, easy to clean and matched the red bottle identically.

Ordered for the kids. Fits perfect. Easy to wash.

Fits my Nalgene perfectly and keeps me from dumping all my water on myself - just what I needed!

The benefits of these splash guards are pretty straight forward, but I had a hard time deciding which to buy. My fiancee has a Guyot Designs one with an opening for drinking and a vent on the opposite side, and that is how I discovered the utility of these things. I was also interested in this Nalgene option, which was less expensive at the time of my purchase. I keep a 32 oz, quart-size Nalgene bottle at home and one at work, so I decided I'd just get both and see which I liked better. I see these suckers as having two pretty basic functions: (1) make sure I don't spill when on a rocking boat or in a moving car and (2) don't fall into the bottle. It's fine to drink out of -- sometimes I guess I manage to block the top of the opening, which is intended to act as a vent, and get a weird slurping sound. I prefer the option with the separate vent. This "sipper" is a hard plastic which doesn't fall into the bottle easily. It's never fallen in accidentally. It will fall in after a few pretty solid taps on its surface, and is easy enough to retrieve (when the bottle is empty). The Guyot Designs "splash guard" I purchased is made of a softer, rubbery plastic. The separate vent is much preferred, but it falls into the bottle much more easily. It can't even withstand one solid tap on the surface. It's also plenty easy to retrieve after it has fallen in. My fiancee's Guyot Designs splash guard is made of a hard plastic, similar to this Nalgene option, but also has the separate vent that I prefer. That is the best of both worlds in my opinion, but I'm not sure how you find that specific product. Good luck!

My husband uses these everyday for work. They fit his bottles well (he has the corresponding nalgene bottles) and they are pretty sturdy. They remove easily too without fear of breaking them. It creates a nice seal so its not leaking around the insert. Would buy again.

This size didn't fit my bottle unfortunately but they were very nice about it and understood. Quality was nice and seemed durable to prevent splashes.

Excellent fit, but way overpriced for a piece of plastic out of a mold. Definitely helpful while driving!

I would say these are OK. They work as described but can be troublesome to install and remove. Have other ones that fit better. They are fine, just not the best.

Lite sämre än förväntad, lite för hård plast, trillar ofta ner i flaskan

I bought this addition for my nalgene bottle mainly because during my research a few people complained that it was difficult to drink from the mouth of the bottle without spilling the contents down your chin. Well this device definitely stops that and fits the bottle perfectly. However, since receiving the bottle I've not experienced any problems without using the easy sipper, but now I've bought it I use it because it wasn't cheap to buy.

Evidentemente es perfecto para la botella de tritán, sin embargo para la de acero es un poco grande y no lo podrás utilizar. El precio es abusivo, eso lo dejo claro...

Je n’ai pas encore essayé ce produit mais il se met en place facilement et ne bouge plus , même en retournant la bouteille et en la secouant. Une bonne alternative aux autres bouchons hors de prix pour réduire la taille du goulot. Convient pour Nalgene 1.5L

appena arrivato sembrava cosi piccolo rispetto alla bocca della borraccia nalgene, ma poi una volta inserito capisci che si incastra davvero perfettamente e che e' molto utile. Con questo accessorio non mi sono piu bagnato mentre bevo . ottimo e consigliato
