The Scuba Force Arctic X-Nine is an insulated drysuit undergarment combining two-layer Tecnostretch with Thinsulate Type B. It places more insulation around the torso and less in the arms and legs to balance warmth with movement.
Why we’ve selected it
A useful option for colder dives when you need more insulation beneath a trilaminate suit. Fit matters as much as insulation: leave room in the drysuit to move comfortably with your chosen layers.
Key features
Two-way front zip and feed-throughs for heater cables and pee-valve tubing.
Zipped arm and chest pockets, plus two hip pockets.
Breathable, moisture-managing fabric.
Fit and compatibility
For use beneath a drysuit. Choose insulation around water temperature, dive duration, activity and your own response to cold. Check reach and mobility while wearing all planned layers; no single temperature rating suits every diver. Standard and made-to-measure options are listed.
Fit and sizing
Choose your size using the manufacturer’s measurements, then check reach and mobility with your planned thermal layers and drysuit. Allow room for your arms, shoulders and legs to move freely. For made-to-measure orders, contact Oceanauts to arrange measurements and confirm the production lead time before ordering.
