OThree Point Below Base Polar-pro Technical Thermal Fleece... Point Below Base (PBB) Internal thermal insulation for drysuits, we feel, is one of the most misunderstood elements of drysuit diving. It is fundamental for divers to understand thermal layering and it's buoyancy implications when deciding what to wear under a drysuit. 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. O'Three's Point Below Base (PPB) layering system is stage one in our development of a multifunctional, interchangeable heating system. Info...
