Drysuit for professional diving: how to choose?

A drysuit for professional diving is chosen according to four key elements: the material (lightweight, hard-wearing trilaminate, or warmer compressed neoprene), the type of seals ensuring watertightness, the extremities (dry gloves, hood, boots), and the thermal undersuit worn underneath. The goal: keep the diver perfectly dry and at the right temperature, intervention after intervention.

Unlike recreational diving, professional use — military, public safety, commercial diving, cold or contaminated water — demands robustness, lasting watertightness and compatibility between all elements. Here is how to build a consistent set.

Why a drysuit in professional diving?

The drysuit completely isolates the body from the water, which is essential in cold water, long dives or polluted environments. It also lets you adjust thermal insulation through the undersuit. Browse our drysuits for public safety and our military drysuits.

Trilaminate or neoprene: which material?

Trilaminate is lightweight, dries quickly and offers great freedom of movement — ideal for frequent interventions and transport. Compressed neoprene provides more thermal insulation and resistance to crushing at depth. The choice depends on your working temperatures and intervention cadence.

Seals and watertightness

Watertightness at the neck and wrists relies on seals (latex, silicone or neoprene). Interchangeable ring systems make it easy to replace seals and add dry gloves without sending the suit back to the workshop.

Dry gloves

Dry gloves keep the hands dry while preserving dexterity. We offer Santi dry gloves, Santi dry gloves with wrist seals and Aqualung commercial dry gloves. See the gloves category.

The hood

The hood protects the head, an area of high heat loss. Aqualung polytex models come in separate or replacement versions. Discover the hoods category.

The boots

Robust, well-fitted boots ensure comfort and protection. The Aqualung Evo 3 and Evo 4 boots are built for intensive use.

The thermal undersuit

It determines your real warmth under the suit. Santi fleece undersuits, such as the fleece jacket and fleece trousers, or the Aqualung MK2 undersuit jacket, adapt to the water temperature.
