Undersuit
THERMOFLEXX

3V

Universal thermal undersuit with interchangeable inserts, designed for diving in cold and very cold water, providing stable thermal comfort in all conditions.

A modern undersuit designed for divers who demand maximum flexibility and thermal protection when exploring cold waters. The innovative system of interchangeable insulating inserts in two thickness options (200 and 400 g/m²) allows the level of insulation to be adjusted to water temperature, dive duration, and current conditions, ensuring comfort, mobility, and warmth underwater.

Three insulation configurations in one product, giving you full control over thermal comfort.

The undersuit offers three usage configurations, allowing you to adapt it to the season, depth, and planned dive time:

Base mode – without inserts – light insulation, ideal for moderate conditions.
Ideal for dives in moderately cold water. Light, breathable, and extremely comfortable, it provides full freedom of movement and basic insulation.
Comfort mode – 200 g/m² inserts – optimal thermal comfort for most dives.
The perfect balance between warmth and flexibility. The 200 g/m² inserts work well in most standard diving conditions, offering a clear boost in warmth without adding excessive bulk.
Extreme mode – 400 g/m² inserts – maximum protection in cold water.
Maximum insulation designed for cold-water diving. The 400 g/m² inserts provide thermal protection even during long, multi-stage dives in demanding conditions.

Unique technology

The undersuit features specially designed pockets—two positioned on the chest and one larger pocket on the back—allowing quick and convenient placement of the insulating inserts. Each pocket is positioned to ensure even insulation distribution without restricting freedom of movement while diving. The inserts are secured with strong Velcro fasteners that keep them firmly in place, preventing shifting or slipping even during dynamic underwater movement. This keeps the entire construction stable and ensures consistent thermal performance throughout the dive, allowing the diver to stay focused with confidence that the inserts remain exactly where they should be.

Advanced solutions

Modular design – quick and intuitive insert replacement allows fast setup for any dive.
Breathable materials – maintain thermal comfort and reduce moisture buildup.
Ergonomic cut – ensures full mobility and comfort inside a drysuit.
Versatility – ideal for recreational, technical, and long-duration expedition diving.
Cold-water reliability – insulation system adapted to temperatures from moderate to extremely low.

One undersuit – full control over warmth. Adjust the insulation to your needs and dive comfortably in any conditions.

Indestructible Heat

CLIMASHIELD 2Apex ™ is a unique tubular filament insulation – “indestructible heat” – is light, very warm, resistant to washing and compression. Thanks to the advanced technology, AquaBan ™ provides excellent thermal performance even when wet, while not hindering the removal of moisture from the body.

The fibers used for the production of the insulation retain their properties and structure despite being used in difficult conditions or repeatedly washed.

Climashield® Apex ™ is the lightest insulation available with the most efficient thermal level. Based on 25 years of experience, It has been created to have 75% larger loft and to be 30% more efficient than any continuous fiber insulation.
