No BS. No fluff. Just maximum thermal defense for elite water operations.

The ThermoCore ULTRA Drysuit Undergarment is engineered specifically for professional divers and maritime operators who refuse to let freezing water cut their mission short. While your drysuit seals out the water, the ThermoCore ULTRA locks in the heat. It provides a highly advanced, low-bulk barrier designed to conquer extreme temperatures without compromising your mobility or trim.

Built with an advanced triple-layer construction, this one-piece thermal liner integrates a rugged polyester outer shell with a high-grade 3M™ Thinsulate™ 100g insulation lining and high-performance Polartec® fabric. The result is uncompromised durability and exceptional thermal performance that retains maximum loft even under intense water pressure. Whether executing demanding deep dives or conducting cold-water rescue operations, step into ultimate thermal protection and extend your bottom time with gear forged for the harshest marine environments.

Triple-Layer Thermal Defense: Integrates a polyester outer shell, 100g 3M™ Thinsulate™, and Polartec® fabric for ultimate insulation and durability.
Double Neck Cover Design: Engineered with a specialized dual-layer neck barrier to completely block cold air and water drafts.
Strategic Elastic Zoning: Applied at the ankles and waist to deliver a secure fit while maximizing mobility and flexibility underwater.
Underarm Ventilation Openings: Built-in breathable armpit vents improve airflow and temperature regulation out of the water.
Secure Tactical Storage: Dual Velcro pockets on both sides of the chest provide safe, accessible storage for smartphones or small gear.
Comfort-Fit Wrists: High-grade stretch fabric at the wrists ensures a comfortable, flush fit that stays in place inside your drysuit seals.
