Orca"s TRN is the first ever training specific wetsuit. The main construction of the TRN is a 2-2.5mm SmoothSkn neoprene front and back with flatlock stitching which balances flexibility, buoyancy and thermal protection. The performance grade SCS coated 1.5mm Yamamoto 39 cell neoprene used on the shoulder panels is highly flexible for excellent range of motion, while the 2mm high stretch jersey side panels offer flexibility and comfort through the full swim stroke and kick. The TRN has a polyester lining which helps protect the wetsuit from the effects of chlorine and warm water, making it ideal for use in pool training and races. People with higher end race wetsuits can also use the TRN as their second wetsuit for more regular training, thanks to its durability.
