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

This thing does exactly what it's designed to do. I'm happy with it. When you put it in the bottle, only push it down until it's where it needs to be. Don't keep pushing or it will fall into the bottle. It fits. Just don't keep pushing it. :)

Great product but you really need to level it out perfectly otherwise it will constantly fall inside water bottle

Love it. Quick and easy to pop into the wide mouth Nalgene. No more water splashing out trying to get a drink in the car or on the treadmill!

Have a baby pink one in the way! I love it!!! Makes drinking so much easier and don't have to worry about spilling water all over yourself.

Use a Nalgene bottle? Have one of these.

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.

Great addition to the 32oz wide mouth Nalgene bottle, I found this helpful to avoid spillage while on the move, easy to remove and clean, and to place it.For almost $4 is a great deal.

This is great for Nalgene bottles

Worked like a charmFits wellArived early

Not the best it could be honestly."It fits snugly into the neck of the bottle" - I found this not to be the case with my bottles. I own two wide mouth 1L bottles and in one it fits ok (not as snugly as in some pics/videos I have seen) and in the other it's just too loose, so much that even if I place it at an angle close the lid and shake the bottle it will become loose into the water.If mine was new I would probably try to avoid exposing it to cold/hot temperatures (don't know if that can influence the size of the slipper).I bought this so I could drink while in a vehicle or while walking and not spill half of it into myself. On the bottle that it fits it does work well and the flow is good. But in my opinion it is waaay too expensive (I could almost buy a new 1L nalgene bottle for this price where I live in).I would advise you to look into the capcap (I think it's by humangear) as an alternative. I don't have one but it will be my choice next time.Hope this was helpful.

A Must have with these wide-mouth bottles. As other reviews had said, should be a thing included with the bottle, or at a lower cost.Fits easy into the mouth of the bottle and fits quite snug, however it does not permanently attach to the bottle, its just sits (quite securely though) in place. Personally i put this in upside down as it find water doesnt drip out to the side as much. Also a tip to people buying this, when drinking or pouring out, the water tends to 'glug', so i drilled a small air hole at the top to allow air to pass through, works a whole lot better now, and i have noticed some aftermarket sippers have this hole also.

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.

Just sits in the top of your bottle to prevent your bottle from just tipping water on your face
