Internal thermal insulation for dry suits, we feel, is one of the most misunderstood elements of dry suit diving. It is fundamental for divers to understand thermal layering and its buoyancy implications when deciding what to wear under a dry suit.
Materials that have been proven in more extreme environments than diving have been used by O’Three in the development and manufacture of a technical, functional, easy to wear set of garments specifically designed for our sport.

So toasty!!!! I use this undersuit while guiding in Silfra in Iceland. The water teperature is 2 degrees in the water and can get down to minus 22 outside. Anything above 0 degrees and I have to take the top off as I get too hot! So most of the time I am guiding with just the salopettes. In the unlikely event I get wet I still stay warm and only notice after I take my drysuit off. I use this with an Ri2-100 but have used it with a tri-lam and been warm too.
