PBB Extreme Base Layer (Gents)

To stay warm it is imperative you stay dry, not just the job of your drysuit, but your base layer/undersuit as well. The first concern is to move perspiration away from your skin. The twin layer of Polarpro technical thermal fleece wicks, breathes and is hydrophobic, which means the fibres do not absorb water. Instead, body moisture is transferred away from the skin and in its place a contour of warm dry air is created. With an additional layer, you will feel the benefit of increased warmth while at depth too.

The Set comprises of Top, Salopette and Socks.  All our PBB Extreme sets come ready to dive in their own zipped carry / stash bag.

More Information
Internal thermal insulation for dry suits is often 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.
When developing these exceptionally warm undersuits, O’Three have selected materials that have been proven in more extreme environments than diving. The result is a technical, functional, easy to wear set of garments specifically designed for scuba diving.
