Description

The Women’s Thermocline Long Sleeve Swimsuit is designed for those who want more warmth and protection than standard swimwear without the bulk and buoyancy of a traditional neoprene wetsuit. Combining advanced fabric technology with a streamlined fit, this versatile garment is ideal for warm-water scuba diving, freediving, snorkeling, surfing, paddle sports, and a wide range of surface water activities.

Constructed using innovative Thermocline fabric, the swimsuit delivers thermal protection equivalent to approximately 2mm neoprene while remaining lightweight, breathable, and neutrally buoyant. This unique performance makes it an excellent option for travelers, warm-water divers, and individuals seeking an alternative to neoprene garments.

The fabric incorporates a soft fleece inner layer that draws moisture away from the skin and transports it through a breathable membrane to the outer nylon surface, where it can evaporate efficiently. This helps maintain comfort before, during, and after water activities while preventing the clammy feeling often associated with traditional wetsuits.

In the water, the membrane helps trap a thin insulating layer next to the body while reducing the movement of colder water across the skin. The result is effective thermal protection that supports longer, more comfortable sessions in the water without compromising flexibility or comfort.

The long sleeve design provides additional coverage and warmth, while the front zip entry makes the swimsuit easy to put on and remove. It can be worn as a standalone thermal swimsuit or layered beneath a wetsuit for extra warmth and protection during cooler dives.

Unlike neoprene garments, Thermocline is machine washable, highly packable, and resistant to damage from folding or compression. It dries quickly between sessions and remains fresh and easy to care for, making it an excellent companion for travel and frequent water use.

Made with recycled materials and designed for versatility, the Women’s Thermocline Long Sleeve Swimsuit offers lightweight thermal performance for life in, on, and under the water.
