By adding the O’Three Deep Skin Short John, this temperature range can be increased.

Unisex fit.


Will Goodman put the previous version of our 65 Semi-Dry Diving Wetsuit to good use achieving a world record CCR dive in 2014, this model of diving wetsuit is even better.

Following a years training Will descended to a record depth of 290m, although because all the gauges stopped at this depth, it is believed that he actually achieved over 300m.

Sticking to our beliefs in what we know about neoprene and diving suits in general, we have made clever use of modern technical fabrics and the latest technology in seal skin finishes. The 65 Semi-Dry is the best diving wetsuit we’ve ever made.

Modern fabrics have allowed all manufacturers to produce products that now stretch and flex like never before. Velcro will attach to some of these fabrics, this small disadvantage is far outweighed by the advantages of these modern fabrics. The issue is easily avoided by always marrying both parts of the Velcro when not in use.

The neoprene

The most critical element of any suit. The neoprene we use gives a high degree of comfort and flexibility, whilst minimising compression, maximising its recovery, therefore keeping you warmer for longer. O’Three’s 65 Semi Dry Diving Wetsuit uses three densities of quality dive grade neoprene.

The fabrics

In order to capitalise on the quality of the neoprene, we need to laminate it with the best fabric combinations. From the durable 210D fabric used on the seat and front of the legs, to the Thermal Plush used internally throughout the Torso, no fewer than 8 different linings have been utilised, each having a specific function and job to do.

The cut

Tailoring and ergonomically shaping remain a priority. Get it right and the detail in marrying the Neoprene and Fabric combinations will come into their own.

Thermal plush

Internally the torso has been laminated with Thermal Plush. This new material combines fibres and a unique weaving technique that will increase warmth and speed up drying times.
