OTF Cap

The little plastic lock clasp broke & water spilled out. Very disappointed. With it broken the metal clasp is difficult to close.

Nalgene does not explain what this lid does nor do the have a picture of it open

Heavy lid can cause water bottle to tip over and spill when the water level is low. Best to use this lid on the wide bottles. Silicone seal eventually stains and won’t come clean. Can’t find replacement. Apart from those problems, this lid is great for drinking from the bottle!

These caps are fantastic, I enjoy using them so much more than the typical wide mouth cap. I don’t even have a problem with mold on the silicone seal. I think perhaps regular, daily or even weekly washing would take care of that.

The silicone seal molds up very fast and is impossible to clean. Once it goes black, it stays black. The cap was a nice idea, it’s easy to drink from, especially compared to drinking from the wide mouth, but the mold issue needs to be addressed. I already received free replacements for my 2 caps, but these have gone moldy again. Nalgene needs to make a wide mouth cap that has the narrow mouth cap on top. This way you get both options, large for easy pouring and filling, and narrow for easy drinking.

Love my OTF bottle and lid. I’ve had mine almost 3 years and have never had a problem with mold inside the lid and my bottle takes a beating! My husband’s bottle which is newer than mine does have mold issues, however. Maybe something has changed with the materials used?

Impossible to clean the silicone seal on the inside of the lid. That’s a deal breaker. Gets moldy fast. After replacing it once I switched to a different brand that’s easy to clean.

I personally love these caps rather than the screw on caps. It is so nice to be able to have a little spout than a wide-mouth lid. I have had the inserts for the wide-mouth but another things to clean.

This OTF cap works well for me. I use it all day every day. It cleans well in the dishwasher and does not have nor need a silicone seal. My water bottle has tipped over many times with no leaks. I’ve gotten another OTF cap to go with my second bottle. Very happy with purchase.

Liked this better than a screw top for accessibility, but the silicone cap is IMPOSSIBLE to keep clean even with regular washing. Additionally, it tips over and if the lock isn’t in place water goes everywhere every time (wrecked my laptop!). Wanted to like this product, but since I’m allergic to mold and can’t get the mold off, cannot recommend.

These caps are fantastic if you can afford to buy new ones every two or three months! The little silicon seal in the cap gets so moldy it scares one! I’ve used bleach, vinegar, baking soda and knifes and still can’t get it off! They won’t even sell us just the silicon seal and it’s not an expensive part!

awful cap for kids. If the lid is screwed on too tight the latch won’t close without a lot of force. My 3.5 yo can’t use it – I barely can. Also, wish it was spill proof or at least fit the spill proof piece to customize for toddlers.

no material details.
no spareparts like silicon sealing

The OTF cap ROCKS! It is the best cap that Nalgene has produced. I love my cap! My well-meaning 89-yr old mother decided to wash my 32-oz Nalgene and broke my OTF. I was so sad but I just found out, today, that it has a life-time replacement warranty! If you never tried the OTF, you must give it a try! 🙂 RF

Nice design, but not perfect. It’s only a matter of time before the metal clip breaks-free from the plastic at its pivot point. Once broken, this prevents the metal band from keeping the top handle securely locked. My bottle’s spilled open several times inside my bag now. This lid has a lot of potential, but still needs improved.

Cheap plastic snap that doesn’t stay closed, have spilled water numerous times, very annoying to use while biking

Love these kids. I wish they were offered as an option with all of the nalgene, in all of the colors and all of the sizes.. I’m surprised I cant custom order a normal 32oz with an O.t.f. lid in the colors I want. I would definitely order one.

Very disappointed in the fragile construction. Thin plastic latch mechanism snapped after two weeks of use, and the top will no longer stay closed. A horrible design by a seemingly reputable brand.

Pretty sturdy lids that take a lot of abuse. I drop my bottles a lot, and hang them from clips by these lids. They open and close quick, too, which helps me make sure I’m hydrating enough in my warehouse job.

The silicone trim on the underside of the flip top does collect grime a bit, but a little scrubbing gets that off easily. The inner seal in the flip top also seems to collect a more permanent grime if you don’t clean it often enough, so clean your bottles often! It’s better for your health anyway.
