Fourth Element Women's Thermocline Shorts

Thermocline provides a solution for many people who suffer from neoprene allergies either by replacing the traditional wetsuit entirely or acting as a barrier, reducing contact between the skin and the wetsuit itself.*

Perfect for all surface water sports as well as warm water scuba, this is revolutionary thermal protection. Lightweight, neutrally buoyant, machine washable, breathable and hypo-allergenic, the Thermocline full suit combines our experience with high technology fabrics with our passion for life in, on and under the water, to produce a truly versatile lightweight wetsuit system.

The fabric ensures that the wearer is more comfortable when out of the water, during surface sports, or when kitting up for a dive. The inner fleece layer draws moisture away from the skin and wicks through the breathable membrane where it evaporates off the Nylon surface. In the water, the membrane traps a thin layer next to the body and prevents colder water flowing over the body, perfect for surfers, freedivers and scuba divers.

Thermocline dries rapidly, often within an hour or between dives – a quick rinse and a squeeze to get rid of excess water before hanging it up inside out should ensure it is ready for your next adventure.

No more smelly neoprene suits – this wetsuit can be machine washed (we recommend using our Sub-30 environmentally friendly washing liquid). Store it safely with other garments and when packing for vacation there’s no need to worry about potentially damaging the fabric – it can be squeezed into that last remaining space in your luggage without any worries.

*It is our experience that skin allergies to neoprene, whilst rare, are also not caused by a single compound and therefore it is difficult to be certain of preventing a problem. Thermocline has been used with a great deal of success by neoprene allergy sufferers, but it is important to consult with a doctor about any symptoms and possible alternatives.

Description

Designed to be worn under a wetsuit or on their own in warmer waters, the Thermocline shorts help to increase thermal protection to the body core . Can also be worn with the short sleeved top to make a lightweight shortie wetsuit. The shorts are a smart alternative to board/swim shorts as the close fitting material won't ride up under a wetsuit. Worn under board shorts, the Thermocline shorts can provide that extra thermal protection allowing you to extend your season in the water with the freedom and comfort of shorts before moving to a full neoprene wetsuits. A high back means it won't ride down when paddling or swimming.
