This is a 2XU R:1 wetsuit, used but in great condition. For tri events it is very fast. Good buoyancy in waist chest and legs. It has stability channels in stomach /chest and grippy forarm bits to get extra propulsion from the catch and pull. I got my best times using this wetsuit but have outgrown it and they no longer make this model.Used about a dozen times in a lake during one summer season. Always rinsed after use, and care taking on and off. No damage other than a few fingernail marks that I have shown on the photos. The back of the ankles have some small splits. See the picture that shows this.
