The fitting process
A drysuit that fits perfectly changes everything
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!

Worn when it counts
Obsessively designed drysuits for explorers
This is dive engineering shaped by saturation divers, cave explorers and people who trust their kit where failure has consequences.
I used both suits – the RI200 for under the ice work and the MSF500 for when trying to film whales and need more flexibility.

What makes a good drysuit
A good drysuit isn’t defined by a specification sheet. It’s defined by how well it performs after years of diving, in the conditions you actually dive in.
The best drysuits balance warmth, mobility, durability and fit. Prioritise one at the expense of the others, and you’ll feel it underwater.

Just received my suit back from O’Three, after having a health check and new neck and wrist seals. The service was quicker that I expected and they have done a superb job, it looks like a brand new suit. Great value for money.
