The Swimrun Aesir Thermal Wetsuit is a new (r)evolution of the Swimrun RS1. The Aesir Thermal is the wetsuit with the most thermal insulation of Orca's Swimrun range. It incorporates the lightweight Light Thermal lining for better heat retention, as well as its construction with a front zipper for more comfortable running and swimming. The 40 + technology provides more flexibility, without sacrificing durability, thanks to the outer fabric of the legs. With the combination of 4 mm-thick Yamamoto neoprene and Light Thermal inner lining, you can enjoy even the coldest swimrun races. These technologies enhance the thermal insulation of the suit without sacrificing elasticity or the light weight you need to face your adventures.  Despite being somewhat less elastic than wetsuits in the Flex range due to its high level of thermal insulation, the optimal combination of materials in this wetsuit will provide you with maximum performance.
