Thermocline - Neutrally Buoyant Wetsuit

The Thermocline neutrally buoyant system represents an evolution in thermal protection, using state of the art materials to maximise performance without compromising on comfort. The Thermocline neutrally buoyant wetsuit system comprises the long sleeved top and the "explorer" giving the equivalent protection to a 3mm wetsuit but weighing less than 1kg (2.2 lbs). Thermocline also provides a solution for many people who suffer from neoprene allergies by reducing contact between the skin and the wetsuit.

Thermocline Full Suit/One Piece

Get the thermal performance of a 2mm neoprene suit, without the neoprene. This is the ultimate warm water-wetsuit. Neutrally buoyant, machine washable, breathable, lightweight and hypoallergenic, the Thermocline full suit combines our experience with high technology fabrics and design with our passion for diving to provide a more comfortable and convenient diving experience. The comfort is not limited to the dive however. The breathable fabric ensures that the wearer is more comfortable when fully kitted up and waiting to get into the water. Weighing less than 1kg, the suit is ideal for travelling divers, keen to keep baggage to a minimum. It is fully machine washable so can easily be kept fresh and clean between trips. The suit is neutrally buoyant, allowing less lead to be worn and it dries quickly, even during the surface interval. Available in Men's and Women's styles.

Thermocline Explorer

Available in both Mens and Womens styles, the neutrally buoyant and breathable Thermocline Explorer enables diving with the need for little or no lead. Fluctuations in the buoyancy of the suit with depth are not a factor as they are with neoprene, and the suit is more comfortable in warm conditions above the surface.

When paired with the Thermocline long sleeved top, it makes a perfect alternative to a neoprene suit, yet is lighter weight and easier to pack when traveling. On its own, the suit can be worn in warmer water conditions or underneath a neoprene wetsuit to add the thermal equivalent of 2mm of neoprene.

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 by the equivalent of an extra 2mm of neoprene, whilst still being neutrally buoyant.

The shorts are a smart alternative to board/swim shorts as the close fitting material won't ride up under a wetsuit.

Finsock Wetsuit Socks

Comfortable lining socks for full foot fins and neoprene boots. Constructed using flat lock stitching and fleece lined fabric, Finsocks minimize abrasion from full foot fins and allergy reaction to neoprene boots whilst eliminating the risk of sores or blisters from rubbing. Worn underneath neoprene boots, Finsocks help to keep the feet a little warmer and assist with the donning of a wetsuit by providing a low friction contact between the feet and the inside of the wetsuit. They are also ideal for children and young adults whose feet are still growing as they can help a pair of fins which are a little too large fit better and last longer.
