Material & Pflege

85% Recycled Polyester / 15% Elastane
Machine wash at 30°C and line dry in the shade
The fabric of this garment has been tested according to AS 4399:2020 and has achieved the following rating: UPF Rating: 50+ / Protection Category: Excellent Protection
Maximum skin coverage helps to prevent skin damage. The UPF rating applies only to the area of skin covered. Protection may be reduced if the material is wet, stretched or from the effects of normal wear or exposure to chemicals. For best sun protection use hats, clothing that provides maximum skin coverage, sunglasses, sunscreen and shade.

The Fourth Element Women's Long Sleeve Hydro-T is a long-sleeve rashguard designed for two purposes: as a UPF 50+ sun-protection layer for water sports and as an undergarment beneath a wetsuit or semi-dry suit. It sits in the Fourth Element OceanPositive Collection, a range built from recycled post-consumer plastic waste.

The fabric is 85% recycled polyester and 15% elastane. The recycled polyester comes from post-consumer plastic waste, giving discarded plastic a second life as a functional garment rather than sending it to a landfill or the ocean. The elastane content provides the stretch needed for a close, comfortable fit during active water sports without restricting movement.

The ultra-smooth fabric surface is a key functional detail for divers. When wearing a wetsuit, particularly a rental wetsuit that may not be a precise fit, friction between the suit and bare skin causes chafing over the course of a dive or a day of water sports. The smooth outer surface of the Hydro-T sits between the skin and the wetsuit, reducing that friction and stopping chafing from tight or ill-fitting suits.

This makes it particularly practical for dive centers, resorts, and snorkeling operations where guests use rental equipment.
The fit has been improved with flattering panels. Flatlock seams run flat against the body rather than raising a ridge, which eliminates pressure points and seam chafing under a tight wetsuit. The construction keeps the garment streamlined so it does not add bulk under a semi-dry or wetsuit.
Thumb loops make donning and doffing straightforward. They keep the sleeves in position while pulling on a wetsuit over the top, preventing the rashguard from riding up the arm during donning.
Sun protection is rated at UPF 50+. UPF (Ultraviolet Protection Factor) measures how much UV radiation a fabric blocks. A UPF 50+ rating means the fabric blocks more than 98% of UV radiation, making it suitable as a standalone sun-protection layer for snorkeling, paddling, kayaking, and other surface-water sports where prolonged sun exposure is a risk.

Water-based inks are used for the chest and back prints. Water-based inks avoid the chemicals used in conventional printing processes, aligning with the OceanPositive ethos of reducing environmental impact across the full product lifecycle.

Fourth Element is a UK-based brand that produces dive and water sports clothing for divers and instructors worldwide. The OceanPositive Collection addresses the impact of single-use plastic waste by using recycled post-consumer plastic as a raw material. Wearing a rashguard also reduces the need for sunscreen in the water, which is relevant for diving and snorkeling in reef environments where chemical sunscreen compounds cause measurable damage to coral.

For divers and water sports instructors asking what rashguard to recommend to students or guests: the Fourth Element Women's Long Sleeve Hydro-T works under any wetsuit or semi-dry suit, provides UPF 50+ sun protection as a standalone layer, is machine washable at 30°C, and is built from recycled materials.

Nach dem Herstellungsprozess des Neoprens werden die überschüssigen zugeschnittenen Materialien recycelt und im Mischprozess wiederverwendet, um weitere Neoprenschichten herzustellen. Insgesamt werden enorme Mengen an Rohstoffen eingespart, der Energieverbrauch reduziert und Abwasser- und Luftemissionen bei der Produktion minimiert.

Wiederverwertete Materialien

Die recycelte Tauchflosse. Es ist die einzigartige Materialkombination, die diese Flosse zu etwas Besonderem macht. Der Kunststoff besteht zu 100 % aus recyceltem Post-Consumer-Abfall-Polypropylen und der Gummi besteht aus recyceltem TPR. Indem wir Materialien auf diese Weise verwenden, verhindern wir, dass Plastik auf Mülldeponien landet oder als Abfall im Meer landet. Dies ist Teil der Mission von four element, OceanPositive zu werden.
