Divewear - Undersuits

With the classic construction of two layers of high insulation, low bulk fabric, the Arctic hat is seriously warm. Warm enough for Doug Allan on the BBC's Operation Iceberg.

The Arctic Legging features secure foot loops that hold it in place when the drysuit is put on. A high waistband minimizes the separation between the top and leggings. Tuck the top into the belt before putting on the drysuit. The lower legs are made up of a single layer to reduce bulk at the ankles, making them easier to put on.

Probably the world's best selling thermal undergarment is now available in a simple one piece option. Featuring the innovative two layer technology pioneered by Fourth Element, the One Piece Arctic provides a simple solution to the challenges of thermal protection.

The Arctic's two layers of high insulation and low bulk fabric ensure exceptional levels of thermal protection.

Constructed with comfort and utility in mind, the minimalist design provides outstanding performance under closer-fitting neoprene drysuits. In a layering system, the Arctic is also suited for use underneath membrane and trilaminate suits.

Using a combination of fastwicking, high insulation fabrics, the Arctic creates a micro-climate around the diver, keeping the body dry and warm. A high density inner fleece provides superior insulation, with maximum comfort and wicking, whilst the outer layer, which has a water-repellent finish, ensures a snug fit

Every adventurer needs a canteen of water. The Gulper is more than just your everyday water bottle though. Stainless steel double wall vacuum insulation means that iced drinks stay cool for up to 24 hours and a hot drink will stay that way for up to 12 hours. Every time you refill this bottle instead of buying bottled water (look out for refill stations cropping up everywhere) you are helping to reduce the production of plastic waste which may end up in landfill or our oceans. The versatile lid means you can drink on the go thanks to the twist and sip valve and the wide aperture makes filling and cleaning quick, simple and spill-free.

The Seeker mask was designed with two main objectives: maximise the diver’s field of vision to be as close as possible to the experience of not wearing a mask using a single lens and to fit everyone – well, nearly everyone. New facial geometry was combined with a soft silicone skirt to provide an outstanding and comfortable fit.

The low volume design allows easy equalisation and mask clearing as well as creating a visual experience which is wider and brighter than ever before – with a near natural field of vision.

Incorporating highly advanced thermal technology and one of the most insulating materials ever developed, the HALO A°R's performance exceeds expectations of any diving undersuit.

Using technology originally created for space exploration and cryogenics, the HALO A°R features the extreme insulation material A°RGON™ aerogel in a compression resistant matrix.

With phenomenal insulation properties, this material enables the HALO A°R to achieve extreme thermal protection from a thinner, less buoyant diving undersuit.

Part of our OceanPositive Collection, these new Hydro-T rashguards are designed to be worn under a wetsuit or semi-dry suit or as a UV shield for all water sport activities.

The fit of these rashguards has been improved with flattering panels, kept streamlined with flatlocked seams. Presented in a palette of classic and ocean inspired colours with water-based prints on chest and back in complementary, contrast tones.

The ultra smooth fabric made with a combination of recycled polyester and stretchy elastane reduces friction between the skin and a wetsuit and helps to stop chafing from tight/ill-fitting suits.

With flat seams and a long body to ensure that no separation between top and leggings develops, the top is the ideal next to skin layer under a drysuit. Thumb loops keep the sleeves in place whilst donning the drysuit and should be removed from the thumb and pushed back through the wrist seals prior to diving.

The J2 Base Layers are designed to give prolonged comfort and thermal performance under your drysuit, thanks to the unique OceanPositive recycled fabric.

Keeping your skin dry through a dive is essential for maintaining warmth and preventing irritation. The J2 base layers excel at wicking away perspiration, creating a dry zone next to your skin for enhanced thermal insulation. The J2 wicking performance also comes into its own when the fabric gets wet. Even in the event of a suit flood, the moisture will be wicked away, and with the right combination of drysuit underwear, will travel further though the fibres of your undersuit, keeping you comfortable and dry.

The men's J2 base layer long sleeve top is designed to wear next to your skin and beneath your drysuit or drysuit thermal layers. Made from recycled polyester, the innovative base layer fabric wicks perspiration away from the skin keeping you dry and giving thermal protection throughout your dive.

A simple, close fitting design, the J2 top feels beautifully comfortable beneath your drysuit thanks to the 4-way stretch fabric, providing optimum protection for your core and arms. The seams sit flat against the torso for maximum comfort, and give a flattering line.

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.

These are a fantastic alternative to neoprene socks. With flat lock stitching and fleece lined fabric, they are ideal under neoprene boots. Thermocline socks help to keep the feet warmer and assist with the donning of a wetsuit by providing a low friction contact between the feet and the inside of the wetsuit.

The convenience of the zip-thru jacket is that it is easy to don and quick to remove. The breathable fabric ensures that it is comfortable whilst preparing to dive and the design allows great freedom of movement along with the ability to unzip a little to keep cool before the dive. Pair this with the leggings to give full length neutrally buoyant thermal protection that dries quickly and is machine washable, meaning that it is always ready for next getting in the water.

The ultimate baselayer for use under a drysuit. Made using Polartec® Powerstretch® originally developed for NASA, the Xerotherm traps a layer of air – a much better insulator than water next to the skin, keeping the wearer drier and more comfortable. The range is designed to be worn under another undersuit or on its own under a neoprene drysuit.

The knit of the Xerotherm fabric produces the fastest wicking effect of any of the products in the fourth element product range. Moisture is drawn out through the fabric along fine fibres and then spreads out over the outer surface. This maintains a thin layer of air next to the skin. This is so effective in the Xerotherm that some wearers report experiencing minor suit leaks during the dive without even noticing until after the dive.
