The Right Gear Changes Everything

Open water isn’t pool swimming.

You’re dealing with changing water temperatures, weather conditions, visibility and currents. The gear you use needs to perform in real environments, not just controlled pool conditions.

The right wetsuit and equipment doesn’t just improve performance, it gives you confidence when you step into open water.

At Streamlined Open Water, every product we stock is carefully selected, tested and endorsed by a professional open water swimming coach.

If we wouldn’t use it ourselves, we wouldn’t sell it.

Our range is built around equipment that performs in real UK open water conditions, not just what looks good on a shelf.
