One Bottle Hydration - 28mm Adapter (No Tube Or Accessories)

Stand alone adapter for Smart water bottle. Tube and bite valve NOT included.

The silicone grommet seals in 3/8” OD tubing, which is the standard used by almost all the manufacturers including Osprey/Gregory/Camelbak.

If you've got a spare tube and bite valve that you like, try this variant!

They’re a great solution if you’re trying to switch from bladder to reusable bottle because you can save money, use parts on hand, and expand your capacity with 28mm bottles when needed!

In November 2024 this adapter got updated with an additional vent and beefier threads that are compatible with even more 28mm bottles.
