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

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.

Fits perfectly. Works great!

I love this thing. I originally bought it for my 32oz bottle, but started using it in my larger nalgene bottles. It fits great in my 32oz bottle, but anything larger and you have to be careful not to push it down too far or it falls in the bottle. Nice and easy to clean, seals the water in good so I don't splash it when I take a drink.

I have mixed feelings about this product. It does work, but it just fits by friction, and I'm always afraid I'm going to push it into the bottle. And then it's another thing to wash.Function:It is designed to insert into the mouth of a standard 32 oz. wide-mouth Nalgene bottle. It basically reduces the flow so it's more narrow. I think this is great when trying to drink on the go. I think most Nalgene users know the feeling of pouring water down your front trying to drink while walking, or riding in the car, etc. This product does well to help with that, but does reduce the flow. I feel like it's a great compromise though. Use it for controlled flow and take it out for high flow, quick refills and easy cleaning.Fit:It fits snug, and just presses into the bottle. The mouth of the Nalgene is straight and the sides of the insert are slightly tapered. Just push it in the mouth and you're good to go! The down side is without some kind of lip, there is no stopper, so I always feel like I'm about to push it into the bottle or it's not pushed in enough.Other comments:I purchased the one I did in a color that doesn't go with any of my bottles because it was significantly cheaper... The normal price at the time of my purchase for the other colors was more than I think the product is worth. I'd say that $5 is a decent price for something like this, but any more and you should just buy a narrow mouth Nalgene and a bottle brush.Final thoughts:A well made product that does what it is supposed to. As a fan of Nalgene products, I'm glad I got one, since it's kind of a novel product... but I probably won't get another.

It works great!

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.

This was a must when I was pregnant and needed to stay hydrated without having the 32oz Nalgene wide-mouth water bottle. It really helped to keep me from splashing and spilling water.There is no smell and the fit is perfect. I wish that the color matched exactly to my lime green cap, but Nalgene has such a variety of cap colors that it probably wouldn’t be cost efficient for them to make these in all colors. It does perfectly match the black cap though.

It was fine but ultimately is more of a hassle to clean so often.
