One Bottle Wide Mouth Adapter - No Flip-Top Lid (For Takeya and Thermo Flask Bottles)

I came up with the idea for the One Bottle Hydration System when I purchased the $15 Takeya/ThermoFlask bottles from Costco instead of the $55 version from Hydro Flask. Once I realized that I could 3D print an adapter for a 3/8” tube I put it on Etsy and the rest is history.

If you’ve got a Takeya or Thermo-Flask with the flip-top lid there’s no reason to buy another one! This set just has the 43” bite valve/tube/adapter assembly. It comes with a rotating clip for 1” and 3/4” webbing - you can upgrade to a magnetic clip for $5 and no extra shipping, and add a blue, grey, black, light brown, or dark brown tube cover!

In March 2023 I sourced food-grade silicone tubing - One Bottle Hydration is the only hydration system enabling users to nearly completely eliminate plastic from the food-contact parts! (as long as you replace your plastic bottle with something inert like stainless steel!)

For the 2023 gifting season I’m adding an accessories combo pack! Now you can get the bite valve cover, the magnetic clip, and a spare rotating clip for $8 - it saves $2 and covers your bases if you’re buying for someone else!
