Nalgene On The Fly BPA-Free Water Bottle Replacement Cap

I partially freeze my water bottles for the day over night, and every so often I accidentally leave one in there. When that happens, occasionally the bottle itself will crack, but more often than not, the threads on the lid just get shredded up and the cap bursts off, so I end up replacing a lid a month or so. when I saw that these were something like $1.50 more, I decided to give them a shot. Here's a few quick pieces of info for future buyers. Pros: -The spout is great. I always get the large mouth nalgenes because it's easier to throw lemon slices in there if I want, and it's much easier for cleaning, but the big mouth can be awkward. This is a pretty good compromise. The spout is about the size of a glass soda bottle (probably a little thinner) and very comfortable to drink out of, but removes for cleaning. -These seem way sturdier than I expected. Nalgene always makes nearly indestructible products, so I don't know why I was surprised, but something about the design seems . . .tenuous. I can assure you, it's not. This is a very substantial product. We'll see how it survives a fall if I mishandle it rock climbing, but for day to day use, I have no doubt that this would survive a fall from head height. -The lid closes with both a plastic catch/push button on the front, and a wire swing gate. This thing is not coming open by accident. My guess is that it would break before it opened in a drop. -I've hung it by a carabiner and attached it to my bike already and it doesn't seem any worse for wear. The loop is definitely handle worthy. -The closing mechanism is a little stiff to provide a solid seal, but I have absolute confidence that there won't be any leaks or drips. Cons: -This obviously adds to the height of the nalgene. It's not much, but it just so happens to be just enough to make it catch on the zipper on my messenger bag, so I'm sure I'm noticing it way more than anyone else would. -The only part on the lid I'm even slightly worried about is the push button mechanism. It seems very sturdy, but getting opened dozens of times a day every day might be rough. I will update if it ever snaps. If I haven't updated, you can assume the latch is still holding firm. Any other complaints I have are cosmetic, so I can't really hold them against the product. It would be cool if there were more colors (the bottle I needed this for was orange). I like the classic nalgene look, these look a little over-designed for my tastes. All and all, when I wind up screwing up a new lid, I'm not sure which way I'll go. It'll probably depend on how this top is holding up. I definitely won't be upgrading unless the current tops on my nalgenes get damaged. A nalgene on amazon is something like $12, parting with $7 for a lid upgrade seems a little silly to me, but if I'm replacing the lid anyways, it's probably a toss up between the classic ones and these. If you need to replace your lid anyways, check them out.

Great top. Easy to open and stays securely closed when clasped. Much preferred to the standard screw top. Our guide in Nepal loved it so much, that we gifted it and the bottle to him. Will definitely be repurchasing.

These work really well for making your Nalgene bottle a little more user friendly. They work great on the 32 or 48 ounce versions. A little more handy on the 32 than 48 though (repeatedly lifting a foot long 3 pound bottle to your face is not the quickest or easiest thing) This is a very handy top. It is also pretty sturdy. There have been at least 2 occasions I have dropped it on a side walk while attached to a full 32 ounce Nalgene. It got a little scuffed but still functions like new. Make sure you use the metal band to lock the lid shut. I forgot to do it a couple times and once the bottle opened in my bag and got everything wet. Luckily there were no electronics so nothing got ruined but it definitely was an eye opener. I am much more careful now. Hydro Flask: I had originally bought this for my 32 ounce insulated Hydro Flask. It's the same shape and size(roughly, very similar. Hydro Flask is a little taller and maybe a tiny smidgen less in diameter than the Nalgene). However these DO NOT WORK on the Hydro Flask. Water leaks around the threads. When screwing the cap onto the Hydro Flask it feels just fine like it's meant for it, it doesn't bind up or feel too loose. Because of this I'm thinking you might be able to get away with using some teflon tape around the threads to seal it better. There's a space on the underside of the cap that looks like it would be perfect for an o-ring. If you could get one just the right size it might also stop the water leakage problem.

This is the second Nalgene replacement cap (same style) I have purchased: I liked the first one enough to buy it again. It is indeed leak proof: has never failed as long as it is fully closed, using the flip-up metal closer. Two things you should consider: 1) the small rectangular plastic latch, on the flip-top, cracked in the middle on my old replacement cap, after much daily use. Still works, but needs the flip-up metal closer to make it secure; 2) mold eventually appeared on the soft rubber seal inside the flip-top, right around where it contacts the drinking spout. I am diligent about cleaning the cap, and it won't scrub off. Another family member had the same experience with this cap style. But since it functions so well, I feel it's worth it. I have taken this hiking; threaded the flip-top through my backpack loop, locked it down with the metal closer, and it stayed put. Will buy again.

I use this for my Klean Kanteen wide-mouth 16oz stainless steel water bottle and for a non-branded bottle. It fits perfectly on both. I like this lid style over many others because it doesn't have a straw part (don't need that) and you can literally use one hand to flip up the lid. Once flipped open, you can set the lid back so that it stays open in a locked position. I love that. Some people have reported that the inside of the lid where the silicone circle is can get moldy. I have never had that problem because when I'm done using it, I immediately clean the lid and set it out to dry somewhere. I've had the lid for awhile now and do not have any mold growing on the inside parts. One other thing to note: Because this lid was not made for my bottles, I don't ever lay the bottles down on their side. I use this lid with a bottle always standing up, whether it's in the bottle sleeve of my backpack or in my hand while walking. I don't actually know whether there's a leak issue if the bottle lays on its side. Just being cautious with it since the lid and bottles are not from the same brand.

I bought this as a replacement to my current Nalgene lid. I have the 48 oz bottle and regularly would end up with water on myself when trying to drink from it. The lid is so straight-forward to use, that I was able to take drinks from my Nalgene without spilling anything during a 2 hour drive back from a friends house. I would 100% recommend this lid based on design and use. The color is exactly as pictured. I have yet to drop it so can't speak about durability but the hinge itself feels decently sturdy enough to pit up and carry the 3lbs of water the bottle holds.

Months ago a dug out an old Nalgene bottle and started using it to try and stay hydrated at work. I quickly got annoyed with drinking out of the wide mouth with the threads on it. It sat for another few months. The other day I cleaned it out and ordered this top. It's exactly what I needed. Good locking lid, easy to chug water from, fits great, and provides a carry handle. I wasn't expecting it, but the flip top even stays out of the way when you tilt back to drink from it. I expected it to hit me in the face. Great product!

Got this lid in today yo replace the regular 32 Ounce lid. This lid is JUST ok..for the price it gets the job done, but it has its faults in my opinion. It feels very cheap, especially the lid opening..this was one of the key considerations in my purchase, just to have a little better hand while carrying it. The hinge is small and I worry with the wight of the water in there it'll eventually be a failing point from carrying by the handle. The opening l/drink spot feels oddly placed, but that i can work with. The latch/click to open is wonky, and can be weird to open. Maybe I got a bad one or something, but I Definitely will be looking into another Humangear lid, as they are far better and worth the couple extra dollars compared to this one. This will work until then.

The other top for my bottle had become mouldy on the rubber seal, so bought this as a replacement. As expected.

漏れは今のところないです！ 使い勝手良きです^ ^

Nalgene OTF Wide Mouth, perfect upgrade you can add to a standard Nalgene bottle. It snaps shut securely and doesn’t leak, even when the bottle is in a backpack or used in a moving car. The flip-top is convenient, easy to open with one hand, and great for quick sips without having to unscrew the entire cap. It fits my 1.5L wide-mouth Nalgene perfectly. Perfect for travel, hike, or as a practical everyday lid.

Lost the spring lock for my juniper on the fly nalgene water bottle within the bottle cap locking device during cleaning. Unable to find spare spring lock anywhere online so have no choice but to purchase a spare bottle cap to have the spring lock removed and reattach back to the juniper bottle cap that lost the spring lock. Overall, I’m just glad nalgene does sell spare bottle caps for their products..👍

Ottimo prodotto è da più di un anno che lo uso quotidianamente e la chiusura è esattamente come il primo giorno. Approvato!
