Afterpay – How it works
The 28mm Flip Cap is a replacement cap with a silicone nozzle that is easy to drink from and auto-seals after taking a sip, and an attached cover that keeps the nozzle clean when shut. It fits HydraPak® products with a 28mm-threaded opening made from 2020 onwards, including the Stow 500ml and 1-litre bottles and the 150ml SoftFlask™.
  • Cover keeps unwanted dust or bacteria out
  • High-flow valve for easy drinking
  • PBA and PVC free
  • Fits any HydraPak® product with a 28mm opening on 2020 models or newer
    • to determine if you have a compatible Stow model, look at the back of the product and see if the Filter Compatible Icon is present (hexagon with two drops of water on top of one another and separated by "---"). If your bottle has this icon, then it is compatible with the 28mm Flip Cap. If not, the 28mm Flip Cap will not fit properly and is not compatible
    • identification on the SF150 SoftFlaskâ„¢ is a little more difficult but it can still be determined by removing the top cap and taking a very close look at the threads. To identify if your soft flask is compatible, look for visible markings on the threaded nozzle of your flask, raised features indicate that your flask is compatible; if the markings are not present, then your flask is not compatible
