The Gold Standard of Thermal Protection: Why Jeff’s Diving World Partners with O’Three

At Jeff’s Diving World, our mission has always been to connect divers with the best experiences the underwater world has to offer. But to explore the depths comfortably and safely, your equipment must be more than just a purchase—it must be a partnership.

That is why I am incredibly proud to represent O’Three as a brand ambassador. When you dive with us, you aren’t just wearing a suit; you’re wearing decades of British engineering, stubborn conviction, and a legacy of excellence.


A Heritage Born from the Jurassic Coast

O’Three isn’t a faceless corporation; it is a company forged in the harsh, beautiful environment of Portland on the Dorset coast. Since 1989, founder Sean Webb has built a business on a simple but rare philosophy: exceptional quality and customer care are inextricably linked.

Operating out of their purpose-built facility at Osprey Quay—the heart of the 2012 Olympic sailing events—O’Three is surrounded by the diverse geology of the Jurassic Coast. This environment demands gear that can withstand the elements, and it is this very landscape that has shaped the design and durability of every suit they produce.

Why O’Three is the “Established Market Leader”

In an industry where mass production is common, O’Three stands apart through neoprene innovation. Their team doesn’t just assemble suits; they evolve them. Each Dry Suit and Wet Suit is manufactured through an established, rigorous procedure developed over 35 years.

As an ambassador, I’ve seen firsthand how their commitment to “blue-chip” engineering standards—bolstered by the expertise of Marcus Darler and the legacy of the pioneering Parry family—results in a fit and finish that is truly second to none.
