About Bo Vest shirt

What is Bo Vest?

Bo Vest is not a life-jacket nor an ordinary life-saver. It is a floatation vest, with an inflatable built-in chamber. The shape of the air chamber is such that when inflated, it covers the wearer’s front, back and sides. The shape guarantees comfortable usage.

The chamber is filled via a tube with a valve, using air exhaled by the wearer. The vest’s buoyancy depends on the volume of air pumped into it.

Two types of Bo Vests are available: loose – made out of quick drying materials with a T-shirt like fit and tight – made using traditional lycra.


… and who it’s for?

We designed Bo Vest with kitesurfers and windsurfers in mind.

However, when testing, we noticed that not only kitesurfers and windsurfers showed interest. Surfers, SUP boarders, snorkelers and swimmers were curious to use it too.

The story of Bo Vest shirt

When running a windsurfing school, I was constantly on the lookout for a good floatation device. Both for those still learning to swim as well as confident swimmers. What I was looking for had to be light, not impede movements when worn, rake up little room in luggage and inconspicuous. That immediately ruled out life-jackets and life-savers.

Then the kitesurfing era dawned. My search for a floatation device continued and became ever more essential. A kite might fly away or lose air leaving a rider in the water with a board which lacks buoyancy.

When repairing kite tubes, an idea was coined to mount an air chamber into a lycra top. When needed the wearer inflates the chambers using exhaled air through the one pump system.

It took us a number of months to come up with an optimal shape for the air chambers. Finally, we managed to design a single chamber spanning the front, back and sides (under the arms).

Testing BoVest over a number of months, we also realised that apart from safety, the thermal insulation is significantly improved – which makes for more comfortable and safer swimming in cold water.
