A nice replacement top for large mouth bottles. Provides a smaller drinking area which helps keep the fluid off your body when the ice shifts or you turn up the bottle too fast.


  • Keeps ice in its place
  • Smaller drinking surface is easier to drink from
  • Well made
  • Cap has a rubberized surface for easy spinning on/off


  • None

I've used Nalgene bottles for close to 20 years and periodically have to replace the tops due to dishwasher heater element mishaps or because the strap eventually wears out. I needed to replace a top recently and I saw this humangear top at one of our Army/Navy Surplus stores and decided to try it.

I have been really pleased with it. The Nalgene bottles are already a bit heavy and this lid doesn't really add much more to it than the normal top. But, you get the major benefit of a top that's easier to drink from and you don't have to worry about the ice shifting and dumping a load of water over your face/neck/clothes.

The cap does add a little height to the bottle but that hasn't been a problem for me.


Here's how the drinking spout looks.


Even though I use this on my Nalgene bottle, it fits several different wide mouth bottles.  The packaging lists: 

  • Works with 32 oz. Nalgene wide-mouth bottles, Nalgene OTG bottles, all CamelBak bottles, Cyclone bottles and other wide-mouth options

Update 1/15: While using this top during my four-day Colorado Trail backpacking trip this past summer, I discovered the spout fits perfectly with my Steripen water purifier, eliminating the need to carry the Nalgene wide mouth adapter.

I occasionally receive gear to field test while camping in exchange for a review.

While planning for this trip, I brought some easy dinner items to quickly toss together. Prior to leaving, I mixed up some sauce at home and transported it in my GoTube. It was perfect! The opening to the soft silicone container is nice and wide. I added some chili sauce, soy sauce, and Sriracha to the tube and replaced the lid and shook it to mix.

The lid has a nice mechanism that will lock the lid to prevent it from opening during transport. When squeezed, the contents are very controlled and there is no drip once you release. I used the FlexiBowl to mix up my concoction at camp. I emptied a tin of canned chicken int the bowel. The top inch or so of the bowel will fold down to create a wider opening.

I used my Go-Bites spork to mix the sauce I brought with the chicken. I ate this on crackers. It was delicious after a long day.

Pardon my dark demo video, it was 9 pm when I got around to eating. Prior to having the Humangear Go-Bites double ended spork, I had a Light My Fire spork. I was doing a side by side demo of the strength and barely put any effort on the ends of the Light My Fire spork and it split in two.

I'm a fan of the Humangear eating utensils. I have also used the DuoBites which are a fork and spoon that slide into each other for transport and so they stay together. I really like both utensils that I have tried! I also have to throw in a GREAT word for the Humangear CapCap! This is a huge step up in my Nalgene game! I don't know how i got by without one! No more spills down the front of my shirt! Bonus!
