Size guide

Internal thermal insulation for dry suits is one of the most misunderstood elements of drysuit diving. It is fundamental for divers to understand thermal layering and its buoyancy implications when deciding what to wear under a drysuit, which is why we developed the PBB Plus Base Layer System.

Staying warm and dry is not just the job of your drysuit, but your base layer as well. This means moving perspiration away from your skin. The PBB Plus Base Layers uses PolarPro technical, hydrophobic thermal fleece, so fibres do not absorb water. Body moisture is transferred away from the skin, and in its place a contour of warm dry air is created.

Why divers choose the PBB Plus Base Layer System

Proven in extreme environments

Materials that have been proven in extreme environments in the development and manufacture of a technical, functional, easy to wear set of garments specifically designed for diving.

Maintain excellent flexibility

This double layer will protect you from the very cold and if sized properly will not hinder your movement when fully kitted up.

The technical fabrics of the PBB Plus Base Layer System trap greater amounts of air than traditional fabrics of the same thickness. The end result is more insulation with less bulk, increased flexibility, reduced buoyancy issues and a lighter weight belt.

Minimal bulk and buoyancy

Our PBB Plus Base Layer system wicks moisture, repels water, and is wind resistant, providing insulation and thermal protection you can rely on.

It is the wearer of the drysuit that generates heat, the suit you choose to wear – as long as it is a neoprene suit – is simply the insulator. A membrane style suit will offer virtually no thermal protection.

The thermal guidance information is purely a guide. If you feel the cold when snuggled up in bed with a winter duvet on all year round, or alternatively wear just a t-shirt in the depths of winter, your reliance on a neoprene drysuit from a thermal perspective is at either end of the scale.

If your base layer/under suit combination is coming up short at certain times of the year, add flexible layers using the correct fabrics to improve your resistance to the cold. Get it wrong and you will increase bulk and buoyancy.

We’re all different, so please be careful and realistic when choosing the appropriate thermal protection – your life could depend on it.
