How we calculate scores →About this gear
PBB eXtreme is O’Three’s Stage 2 drysuit undergarment set. Double-layer Polar Pro fleece is used throughout the top, salopettes and socks, with a roll-top dry bag included for transport.
Consider before buying
The extra layers need space beneath your drysuit. P-valve routing is listed for the men’s version, so confirm the exact cut before ordering. Luke Evans’s 2026 Scuba Diver review reports warmth and unrestricted movement in his quarry dives, but supplies no numeric overall rating.
Our take
Choose eXtreme if the double-layer construction fits the conditions and your drysuit without restricting movement. Compare PBB Plus for a different layering arrangement and packing bulk. The independent account is useful supporting experience, not a universal promise of warmth in low-single-digit water.
