The capCAP was humangear's first product, and its popularity has increased every year since we launched it in 2008. Now, after 10 years on the market, we’ve gone back to the drawing board in order to add more compatibility and functionality with stainless steel wide-mouth bottles.

The capCAP+ is not only compatible with more bottles than the original capCAP, but it also has some great new features like the “CapKeeper” that holds the small cap back when you drink and rubberized grips on the small cap that make it easier to twist open.

The capCAP+ is 100% BPA-free, polycarbonate-free, and phthalate-free, and both caps are made with FDA-approved, food-safe polypropylene (#5) plastic. Both small and large cap gaskets are made from food-safe silicone.

capCAP is the civilized 2-in-1 accessory cap designed to work with Nalgene, CamelBak, and most other popular wide-mouth drinking bottles. The new, re-designed capCAP+ is also compatible with Hydro Flask wide-mouth, Nalgene Stainless, and Guyot Stainless. 

Most wide-mouth bottles are easy to fill and clean, but the standard opening is too big to drink from without spilling. Narrow-mouth bottles are great to drink from but you can forget about putting ice cubes in them, let alone cleaning them. And bottle inserts don't really fix a spout that was never meant for daily drinking.

capCAP offers the best of both worlds. Drink spill-free through the small spout, and then clean and fill easily with the large cap. Don't forget that the wide, rounded strap is more comfortable to hold too.

The new capCAP+ has a few additional cool features like the "CapKeeper" that holds the small cap out of the way when drinking and rubberized grips on the small cap.

capCAP+ is 100% BPA-free, polycarbonate-free, and phthalate-free. Both caps are made with FDA-approved, food-safe polypropylene (#5) plastic. It is also covered by our lifetime warranty.

FAQ

 

Is the capCAP+ compatible with stainless steel bottles?
The capCAP+ is compatible with most stainless steel bottles thanks to some upgrades we made to the seal in the large cap. This includes Hydro Flask wide-mouth, Nalgene Stainless, and Guyot Stainless. It is not compatible with Klean Kanteen though. The original version of the capCAP was not designed to work with stainless steel bottles and is not compatible.

What are the heat restrictions with the capCAP+?
We do not recommend that the capCAP+ be used with fluids over 160F/71C. Fluids over 160F/71C should be allowed to reduce in temperature before being used with a capCAP. Once cooler than 160F/71C, tighten both caps firmly to prevent the chance of leaks and potential for burns. capCAP+ is not rated for carbonation.

How do I know if I have an original capCAP or the newest version?
The newest version of the capCAP is the "capCAP+" and it has only been available on our website since August 2018 (and will be available with other retailers beginning in January 2019). The capCAP+ differs from the original capCAP in the following ways:
-capCAP+ features a "CapKeeper" feature on the strap that allows you to temporarily hold the small cap to the strap so it's out of the way when drinking.
-capCAP+ features silicone gaskets on both the small and large caps.
-capCAP+ features more angular grip features on both the small and large caps, rather than the original, rounded grip cutouts on the capCAP.
-capCAP+ has modified threads that allow it to seal on insulated stainless steel bottles. See the "Compatibility" section below for more information. 

What other water bottles are capCAPs compatible with?
Both versions of the capCAP work with most popular BPA-free wide-mouth bottles. If you refer to the capCAP compatibility information below (in the compatibility section), you will find more specific information on compatibility. Please note that there are too many bottles on the market for us to know all of the ones that are compatible. So if you discover a new compatible bottle, please let us know. We will add it to the site.

Why does leaking occur between my water bottle and the capCAP+?
If leaking occurs, you are likely using a water bottle that is not compatible with the capCAP+. Please refer to the capCAP+ compatibility information below.

What are the thread dimensions of the top cap?
The smaller cap (or top cap) is non-standard and was designed to work solely with the capCAP+.

Where's the most interesting place that humangear has had a meeting?
There have been some pretty epic meeting locations, but we'll have to go with the inside of a Toyota Chinook overlooking San Francisco from the vista point at Twin Peaks.

What are the care and cleaning instructions for the capCAP+?
The capCAP+ should be washed before first use. To clean, hand wash in warm soapy water. If your capCAP+ begins to have an odor, we have a number of other suggestions including soaking it in warm water with lemon; soaking it in warm water with baking soda; washing it in a dishwasher away from the heating element (be sure to remove the strap first as the strap isn't dishwasher safe) or follow some of the recommendations for cleaning Nalgene bottles.

Was there a version of the capCAP that was recalled?
Yes. The recalled capCAP was only sold from November 2016 through February 2017. The most notable differences between the capCAP+ and the recalled capCAP are that the larger, bottom cap is rubberized on the recalled capCAP and the small, top cap does not have a gasket on the recalled capCAP. If you believe you have a recalled capCAP, please reach out to service@humangear.com. For more information on the version of the capCAP that was recalled and to determine if you have a recalled capCAP, please visit the Recall Information page of our website. 

What about the humangear stainless steel bottle -- casq?
Right now, we're working on relaunching this new version of the capCAP. That said, we still plan to introduce the casq bottle in the future. Stay tuned.

Compatibility
 

The capCAP+ (available on our webstore now and in retail shops in January 2019) works with even more "wide-mouth" (63mm-opening) water bottles than the original capCAP. The capCAP+ works with all of the original bottles (below) as well as with most wide-mouth stainless steel bottles like Hydro Flask wide-mouth insulated SS bottles, Nalgene SS (single walled), and Guyot SS (singled walled). The capCAP+ is *not* compatible with Klean Kanteen wide-mouth insulated SS bottles. While it is possible that the new capCAP+ may work with other bottles that have similar 63mm openings, we do not claim compatibility with any other bottles not listed here.

The original capCAP (2008 - 2018) works with many popular 63mm wide-mouth bottles including: Nalgene 1L (HDPE, Everyday, PC), Nalgene 48oz “Silo” bottles (HDPE, Everyday), Nalgene SS, Guyot SS, Nalgene OTG (Everyday, PC), all CamelBak Better Bottles, CamelBak Chute and Eddy bottles, and Cyclone (PC). The original capCAP is *not* compatible with Hydro Flask and Klean Kanteen wide-mouth bottles. Some customers have nonetheless tried the original capCAP on the Klean Kanteen and Hydro Flask bottles and have reported mixed results (i.e. we’re told they work on some of those bottles but leak on others). Despite these mixed results, we stress that the original capCAP was *not* designed to work on either the Klean Kanteen or Hydro Flask bottles and we do not recommend use on those bottles. The original capCAP is not compatible with the 16 oz. Nalgene bottle either.
