Orca Women's Core TRN Open Water Swimming Wetsuit

Perhaps Orca's most recognised Swimming wetsuit, the TRN Wetsuit makes a welcome return, newly re-designed and making a comeback as the new Orca TRN Core Open Water Swimming Wetsuit. Superb all-round wetsuit for the majority of open water swimmers. The flexibility in the shoulders allows for greater comfort and movement while the more neutral buoyancy effect of the neoprene used through the body panels ensures the Core TRN Open Water Swimming Wetsuit will greatly appeal to breast stroke swimmers as well as front crawlers. 

Orca's TRN swimming wetsuit always had extremely popular appeal and the new Open Water Core TRN Wetsuit builds on those solid foundations. The 3mm thick neoprene in the torso and legs will provide you with the necessary thermal insulation so that you can extend your adventures at sea without worrying about low temperatures. The 3mm panels will allow you to maintain neutral buoyancy, improving your position and allowing you to move through the water quickly.  

The Core TRN Open Water Swimming Wetsuit features high flexibility and neutral buoyancy. The torso panels contour the body shape well providing superb comfort and fit while the flexibility in the neoprene used in the arms and shoulders has a great range of movement. A superb wetsuit for any open water swimmer or novice triathlete the Open Water Core TRN wetsuit will appeal to those swimmers looking for a more than basic open water swimming wetsuit at a realistic price without going overboard on unrequired features. 

Orca's Infinity Skin wetsuit lining provides the feeling of absolute freedom. Designed based on a high-elasticity nylon incorporating bamboo fibres, natural eco-friendly materials, this technology is applied to the wetsuit lining helping provide greater flexibility. The Infinity Lining helps maintain body heat longer, reduces body odour and the appearance of bacteria in your wetsuit.

Orca utilise various forms of Yamamoto neoprene throughout all their swimming wetsuits, known for its durability, is lightweight and high performance.  The panel layout, construction, linings and finishes, the variety of neoprene thicknesses and high quality materials used in construction of the Orca’s wetsuit range ensure they remain one of the world’s most recognised swimming and triathlon brands.

Orca Women's Core TRN Open Water Swimming Wetsuit Features

  • Flexibility
  • Yamamoto 39 neoprene is used together with 2mm Infinity Skin high-end lining helping provide more flexibility in all phases of the swim stroke. The high elasticity of this neoprene allows it to be used in different areas of mid-range wetsuits. This material requires between 45% and 35% less force to stretch than conventional neoprene.
  • Thermal insulation and buoyancy
  • Yamamoto 38 neoprene technology in the core torso panels to ensure sufficient thermal insulation for workouts. Its 3mm thickness ensures 77% more protection than if you did not wear a wetsuit. This neoprene is used in the torso and leg areas as the elasticity is not so essential and has a more compressive feel.
  • The Yamamoto 38 and 39 cell neoprene combine to give the TRN Core OW wetsuit a more neutral buoyancy effect helping provide a more even body position in the water making the TRN Core OW wetsuit ideal for breast stroke swimmers.
  • Zero Chafing
  • The lining in the neck area reduces friction and the likelihood of chafing. The material is soft to the touch and better for contact with the skin.
  • Hydrolite lining helps minimise saturation to make the wetsuit easier and quicker to remove
  • Infinity Skin lining provides the feeling of absolute freedom. Designed based on a high-elasticity nylon that incorporates bamboo fibres, this technology is applied to the lining of Orca's wetsuits to offer greater flexibility with each stroke. This cloth maintains body heat longer, reduces body odour and the appearance of bacteria in your wetsuit. Made from natural eco-friendly materials to prevent the appearance of skin irritation and care for the environment.
  • YKK#10 a strong rear zipper with guaranteed quality featuring the YKK seal which is more durable and sturdier than others on the market. Long webbing tape helps make the zip easier to fully undo by yourself.
