Unless you’ve bought your wet / semi-dry suit from a bargain basement outlet, gone are the days of needing a Rash Vest to protect against dubious neoprene, aggressive seams and itchy linings.

O’Three’s long sleeved Rash Vest will shield you from all of the above and because of the quality of fabric, if worn on its own, this vest offers additional UV/UPF50 protection and a practically impenetrable barrier against jellyfish stings.

Black with white and grey graphics.

When and where to wear

Use in or out of water.

Great for warm water swimming and diving, in the pool or as a base layer under a wetsuit.

For four decades, O’Three has built its reputation on one thing: a properly tailored 5mm neoprene drysuit, worn with the correct undersuit. Trusted by divers worldwide, the MF5 has become synonymous with strength and reliability.

The new MF5 honours that legacy while moving it forward, delivering enhanced insulation, comfort, flexibility and durability. True to our heritage and engineered for today’s diver, it’s built to perform for years to come.
