With its unique Nylon construction, the Watery Swim Buoy & Dry Bag in Fluo Yellow is more durable and resistant to holes in the fabric than its PVC counterparts. With this bag around your waist on your open water swim, you'll be more visible to other watercraft as well as those on land. You can also carry belongings such as your cell phone, towel, keys, and clothes in the sea bag to avoid leaving them on the beach during your swim

Most popular sea bag among open water swimmers

What makes this Swim buoy & dry bag 28L special is its Nylon construction. Most other sea bags are made from the less hard-wearing and durable PVC material. This material also gives the surface a smoother finish so it glides more easily over the water, ultimately making it our absolute best-selling swim buoy & dry bag.

Its large 28L size also allows you to carry all your valuables out on the water, including your cell phone, towel, keys, clothes, etc. All will be 100% protected from water in the protected compartment inside.

If you prefer to have easy access to and be able to use your phone during your open water swim, the exact same sea bag with Window is available here.

For these reasons, this is our most popular sea bag

  • The Watery Swim Buoy & Dry Bag is here in the green colour, which provides a high degree of visibility to others in and on the water as well as people from the shore. This model is also available in several other bright colours: Pink, yellow and orange
  • The sea bag has a capacity of 28L, which gives you room to carry your towel, change of clothes, wallet, keys, and water bottle in the sea bag at the same time
  • The dimensions of the sea bag are 36 × 72 cm, which gives the sea bag 17.5 kg of buoyancy out on the water if you need a rest. Plus, it's big enough to be seen from a distance
  • The weight is just 800g, making it one of the most lightweight sea bag on the market
  • The sea bag is made of 100% nylon and coated on the surface with PVC. Nylon is generally more durable and resistant to sharp objects, so they tend to last longer. The PVC on top gives it a nice finish, so it glides more easily over the water
  • On the top, the Watery logo is even placed as a reflector, so you also remain visible in the evening when the sun is going down
  • The sea bag has 2 handles added on each side, making it easier to carry the sea bag to and from the water and to have a rest during the swim
  • The structure of the bag itself consists of two compartments, unlike classic sea bags. One with an opening at the top for storing your stuff and the other for inflating with air. This provides the optimal and highest degree of buoyancy on the sea bag
  • A valve has been added on both sides of the sea bag to inflate the sea bag
  • A special long strap is included with the sea bag, which ensures that no matter your height, it will fit you and can be quickly and easily adjusted around your waist. The customizable length ensures that the sea bag follows you naturally without interfering with your leg kicks while swimming
  • At the end of the sea bag, we've added a whistle built into the buckle for use in emergencies

How to use the sea bag

  1. Put your belongings such as clothes, towel, keys, and wallet into the bag itself
  2. Fold the top of the bag together
  3. Clip the bag together
  4. Blow air into the bag at one of the valves (takes a maximum of 30 seconds)
  5. Buckle the strap around your waist and swim

All in all, the Watery Swim Buoy & Dry Bag is a great open water swim bag for when you require the most durable and long-lasting sea bag that provides a high degree of buoyancy, adequate visibility and storage for your valuables.

Super buoy

Super buoy

I bought the buoy for my daughter and used it in the sea for the first time. It gave me a good feeling and my daughter more freedom, even when the sea is a little more stormy. Good quality and was delivered super fast. This is the second time I order from Watery and everything has always been good.

Renée Benson
I had to wait more days

I had to wait several days for my delivery, but got information from Watery & Budbee and felt safe.

Mary Alnemark

It holds tightly. Visible at a long distance. Haven't needed to use the buoy as a floating agent. Swims on. :swim:

Lise H.

Hi, sea bag is super working just ok. Has also been used in the pool as a swim help for the little ones, the belt around the stomach and the sea bag is there with a single move. Just so satisfied.
