The pursuit for drysuit perfection is what drives and inspires us and our passion for customer care is obsessive. It’s that simple.
International reputation
A reputation for quality, reliability and integrity has helped O’Three gain a following of niche diving communities throughout the world.
Excellence in customer care
Buying a drysuit from O’Three means buying into a company that has a customer care philosophy at the heart of everything we do.
Pushing the envelope
The suit of choice for many boundary-breaking cold water endeavours, where run-times can run into double figures and drysuit redundancy is not an option.
Built around you
We start by listening. Only then do we tailor and customise your suit around the way you dive.
Craftsmanship, materials and customer care unsurpassed
Starting with the best materials available, each drysuit is manufactured to an established procedure that we have developed and evolved over 35 years.
Beyond your purchase, our dedicated O’Three team remain at your service with specialist advice and support.
I have an O’Three drysuit I estimate I’ve spent over 5,000 hours underwater – from the antarctic to the arctic – and it’s still in my dive bag on every cold water diving shoot I go on today. I know that at the heart of what I am about to do is a piece of kit that has my back and I never need to worry about in any way.

5☆ service from start to finish. I'm new to scuba so buying a deysuit for the first time is a big investment coupled with everything else you have to buy. These guys no there stuff and the home fitting service was amazing. The whole experience of getting into a drysuit that was tailored and fitted for me was so easy. They sent out suits to try and all of the deliveries and collections were seamless. The delivery date for the completed suit was bang on and the actual suit is fantastic. I can not recommend OThree enough for quality, service and experience. Thank you so much I'll be back for a wetsuit soon. I have the Port 10 with Kubi gloves and dived it for the first time last week, I'm so impressed. Thankyou
Absolutely first class customer service and tailoring of my drysuit. Before, my buddies struggled to zip me up. Contacted O’Three, really got to grips on where I needed the suit tailoring through sending photos of me in it. Fully briefed on the options and costs. Went ahead and returned in…

The thorough 5.5 page sizing guide/ test suit/ video call/ proactive user friendly parcel handling approach/ the welcome pack/ the personalisation/ the optional extras/ the spares & various solutions & of course the suit itself – all top notch. Highly recommend.

Your made-to-fit suit delivered to you, complete with a quality suit bag, changing mat, Jollop seal lube and Bees wax – everything you need for your first dive in your O’Three drysuit!
I live in Scotland so was a bit hesitant about buying a made-to-measure drysuit online. Well what a pleasant surprise dealing with O’Three. Excellent service from start to finish. Well done!
