Complete With The Treatment That Provides Optimal Performance

The Orca Openwater RS1 Thermal Wetsuit provides the most thermal protection of the Orca range of wetsuits. It features an inner lining that helps maximize heat retention for open water swimming. It also has a second layer of "batwing" neoprene that provides more insulation down the zipper and neck areas, minimizing the inflow of cold water.

In the torso, Yamamoto 39 technology 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. Yamamoto 40 on the shoulders and back combine 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. The Infinity Skin 2 inner lining provides a feeling of absolute freedom. Designed from high-elasticity nylon incorporating bamboo fibers, this technology is used in the lining of the wetsuit to maintain body heat longer and reduce 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.

To avoid heat loss in the back through the zipper, the Orca Men's Openwater RS1 Thermal Wetsuit features a "Batwing" construction 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. The combination of laser cutting on the neck and the inverse Velcro reduces friction, preventing any abrasion on the skin. This allows for a comfortable snug fit, reducing friction and water entry from the neck area into the suit.


  • Durable Yamamoto neoprene is lightweight for a high-performance construction
  • Yamamoto 40 technology requires 72% less force to stretch than plain neoprene
  • Yamamoto 39 neoprene has high elasticity for short-stroke and long-haul movements
  • Super Composite Skin (SCS) treatment guarantees optimal performance
  • Infinity Skin 2 inner lining allows for greater flexibility, maintains body heat, and reduces odor
  • Combination of laser cutting on the neck and the inverse Velcro reduces friction
