Step by step

  1. 01
    Seal the Gateway Valve

    Insert the gateway valve and turn clockwise until the valve is securely sealed. This will stop any air escaping from the swim buoy before you inflate it, or when you want to add more air.

  2. 02
    Pack your Essentials

    Add any items you need to carry with you during your swim. Remember, we advise avoiding placing sharp items inside the bag. We also recommend using an additional waterproof bag for any electrical items.

  3. 03
    Inflate the Buoy

    Make sure the bonnet cap is unscrewed and use the opening to inflate the swim buoy with a few big breaths of air.

  4. 04
    Seal the Bonnet Cap

    Once fully inflated, seal the bonnet by fixing it over the gateway valve and turning clockwise.

  5. 05
    Roll and Clip the Buoy Shut

    Roll the top of the swim buoy over 3-4 times before bringing the clips together and clipping it shut. At this stage you should check that there is no air escaping from the buoy by giving it a light squeeze.

  6. 06
    Attach the Tether Strap

    Thread the looped end of the tether through the plastic rings located on each clip of the buoy. Then thread the rest of the tether through the looped end of the tether strap to secure it to the buoy.

  7. 07
    Adjust the Waist Strap

    Use the sliding bars to adjust the waist tether to fit comfortably around your waist.

  8. 08
    Get Out in the Open Water

    You're ready to go! Enjoy exploring the benefits of open water swimming and remember to always swim within your abilities.

How tight should the waist Strap be?

Snug, not tight.

You should be able to fit two fingers between the belt and your waist.

If it’s too tight, it can restrict movement. Too loose, and the buoy may drift side-to-side.

How do I tell when it is fully inflated?

Inflate the buoy until it feels firm, then stop.

Avoid over-inflating. A small amount of give improves durability and helps the buoy ride smoothly on the water.

Can I swim with it attached at all times?

Yes.

The buoy is designed to be worn throughout your swim and will not affect your stroke or breathing when set up correctly.

What essentials can I pack inside the buoy?

The buoy is ideal for small essentials such as keys, phone, nutrition, and lightweight clothing.

Pack items evenly, roll the top down tightly before clipping, and keep heavier items closest to the base of the bag to maintain balance in the water.

Always double-check the seal before entering the water.

Can I buy a replacement Buoy Tether or Waist Strap separately?

No. We don’t offer replacement tethers as standalone items. We recommend buying a replacement buoy or finding an alternative strap from other stores.

Is a swim buoy a safety device?

A swim buoy is a visibility and confidence aid, not a personal safety or rescue device.

Always swim within your abilities, choose conditions that match your experience, and follow local open-water safety guidance. The buoy is designed to support your swim, not replace awareness, preparation, or good judgment.
