How we calculate scores →About this gear
The PBB Plus system combines a fleece top, salopettes and socks for wear inside a drysuit. O’Three calls it Stage 1 and supplies the pieces in a zipped stash bag. The salopettes have a double-ended zip and provision for P-valve routing.
Consider before buying
This is dry insulation, not a wet layer or a waterproof suit. Check how the top and salopettes overlap and whether their bulk fits your drysuit comfortably. Reviews of the separately named eXtreme system do not establish the Plus system’s performance.
Our take
Consider Plus when you want a coordinated undergarment set with pockets and practical entry. Compare eXtreme if you are specifically looking for the double-layer Polar Pro construction. Choose with the rest of your exposure system in mind; neither the Stage 1 label nor fleece alone establishes a personal temperature limit.
