The Openwater RS1 thermal wetsuit is the wetsuit that provides the most thermal protection in 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 "batwing" neoprene that provides added insulation along the zip and neck areas, minimizing the influx of cold water.
EXTRA WARM
In the torso, Yamamoto 39 technology which is up to 5mm thick provides maximum thermal insulation where it is needed most, without affecting the swimmer's positioning or limiting movement. This material provides 85% more insulation than not wearing a wetsuit. The Thermal X performance inner lining retains heat more efficiently than our standard liners. It is also comfortable and soft to the touch.
YAMAMOTO 40
Yamamoto 40 is used on the shoulders and back together with the Infinityskin lining. This material can stretch up to 130%, more than double its original size, providing maximum performance in your swim. Due to the wide range of motion that occurs in the shoulders, it offers 72% less resistance than a conventional wetsuit.
"BATWING" CONSTRUCTION
To avoid heat loss in the back through the zip, this model features a "Batwing" construction made up of a second layer of neoprene. This layer prevents water from seeping through the zip and coming into direct contact with the body, keeping a layer of warm water inside. It also ensures a comfortable fit around the neck, reducing friction and water entry from the neck area into the suit.
