CHECK THE SIZE CHART (in the image section above) The Orca women's Openwater RS1 Thermal Wetsuit in black and orange is the wetsuit that provides the most thermal protection of the Orca range. It features a specially developed inner lining to maximize heat retention for open water swimming. It also has a second layer of €œbatwing" neoprene that provides more insulation down the zipper and neck areas, minimizing the inflow of cold water. Utilising the best materials available on the market, Orca have created the best openwater wetsuit. Features Yamamoto 39 technology in the torso, which is up to 5mm thick, provides maximum thermal insulation where it is needed most, without affecting the positioning of the swimmer or restricting movement. This material provides 85% more insulation compared to not wearing a wetsuit whilst being comfortable and soft to the touch. Yamamoto 40 is used in the shoulders and back together with the Infinityskin lining. This material can stretch by up to 130%, more than double its original size, providing maximum performance in your swim stroke. For the wide range of movements that occur in the shoulders, it offers 72% less resistance than a conventional wetsuit. Batwing construction to avoid heat loss in the back through the zipper, consisting of a second layer of neoprene. This layer prevents water from seeping through the zipper and coming into direct contact with the body, keeping a layer of warm water inside. It also guarantees a comfortable snug fit in the neck, reducing friction and water entry from the neck area into the suit. Super Composite Skin (SCS) Infinity Skin 2 inner lining provides a feeling of absolute freedom. Designed from a highelasticity nylon incorporating bamboo fibers, this technology is used in the lining of the wetsuit to provide greater flexibility in every stroke. It maintains body heat longer and reduces bad odors and the presence of bacteria in your neoprene. It is also composed of natural and environmentally sustainable materials, to avoid skin irritation and to care for the environment. Ultimate Seal Collar to prevent any abrasion on the skin, using a combination of laser cutting on the neck and the inverse Velcro to reduce friction.
