Nalgene Easy Sipper - Designed specifically for your NALGENE 32 Oz wide mouth bottle

Fits perfectly. Works great!

No spilling on myself. Amazing. Should’ve got it sooner.

I got my first Nalgene and instantly wondered how people have been using these wide lip bottles without getting a wet lap. This little product sorted out the splashing immediately. It's not a tight fit, just kind of rests in the bottle perfectly, removes easily.

Well, the TITLE explicitly says, "Nalgene Easy Sipper - Designed specifically for your NALGENE 32 Oz wide mouth bottle". I bought it for this Nalgene Wide Mouth Water Bottle and it fits. Looks comically small when it arrives, but I tucked it into place no problem. Haven't used it much, so I plan to come back to update how it does. But as of right now, it fits as it should.One thing I never care about with Nalgene bottles is the wide open mouth that I basically waterboard myself with each sip. This helps funnel the flow, providing a better hydrating experience.

Top five things of note:[1] THESE STAY CLEANER, LONGER -- These are very smooth plastic material rather than the rougher and more porous texture of silicone, so there's less "attachment surface" for scunge and growth of things like mildew and algae -- which are very possible / likely when using wide-mouth Nalgenes outside of refrigeration or colder temperatures all-day. (vs. the silicone ones will "grow things" which will require both physical scrubbing AND chemical treatment like a soak in vinegar or hydrogen peroxide to mitigate / remove / kill).[2] SMALL TAB / RIDGE MAKES EASY AND CLEAN INSTALL FOR USE AND REMOVAL FOR REFILL -- No need to stick your finger or a tool into the openings to remove these -- which can introduce whatever is on your finger / tool at the time into what ought to be your clean drinking supply (yuck!). Simply grab / grip the little flange and place / remove! Could use a Leatherman (tm) or first aid tweezers or forceps if a tool is better option (dexterity in cold weather, gloves, hands covered with yuck, etc.)[3] PERFECT FIT FOR WIDE-MOUTH NALGENE -- So perfect, I wasn't sure whether it would just fall in with use or a bit of pressure! So far, so good; clearly, I was used to the "it almost fits ... and DANG now it's * in * the Nalgene" experience with silicone in the past. I'm still getting used to it, tbh.[4] TOP SHELF OF DISHWASHER AND IT GETS CLEAN -- Again, I think it's the rigidity of this plastic that helps it get cleaner and stay cleaner -- results are very similar to plastic food container lids, where you may have some random particulate (errant food particles or crumbs of powdered dish detergent) which either brushes off or you can rinse / towel it off before use.[5] NO DISHWASHER SOAP RESIDUE / DISCOLORATION -- Another "vs those silicone ones I have" observation, where I notice that the silicone tends to accumulate / adhere to the more eco-friendly brands of powdered dishwasher detergent -- a kind of cloudy almost hard-water buildup that doesn't come off readily (or at all). Mostly a cosmetic thing, but/and certainly a nice outcome when I'm using these at home vs. on the trail / river.

Works great. We got one and loved it so we got another. It’s worth trying if you like ice in your cup.

Fits Nalgene bottle perfectly

I super love this Easy Sipper. I have a tendancy to just throw my bottle back and splash myself, lol, so this has saved me more than a few times already. It's easy to install, to take out and to clean. It feels secure once you put it in, I just kind of slide it until it feels a bit tight - unlike others, I haven't pushed it so far that it pops into my water bottle - it's pretty easy not to. It has a beveled edge around it, so you don't even notice it's there when drinking. It doesn't move around once you've got it in place, doesn't interfere with the lid at all.There are no finicky parts here for mold to grow in, as it's just one piece, which appeals to me because I hate taking apart 20 pieces of a water bottle lid just to clean it properly. To get it out, I honestly just stick my finger in the hole and pull, maybe that's wrong, I'm not sure. I will say too, I can easily refill my water bottle from my brita without removing it. It feels very solid and well-made, plus, it's BPA free! I think it was true to color too, so color-matching to my bottle was easy.Anyway, for something so cheap this was a perfect addition to my Nalgene and has made it my favorite at home/cold weather water bottle.
