If competing in a triathlon is in your future, the best gear option is a triathlon wetsuit, which is designed to provide buoyancy and maintain mobility. However, recreational and non-competitive swimmers can also benefit from wearing a wetsuit. Wetsuits for swimming can be worn in open waters or in pools. For ocean or lake swimming, a wetsuit is suggested when water temperatures drop below 65 degrees. In those conditions, swimming wetsuits provide insulation from the cold and protection from rough water conditions. Whether they are worn in the ocean or in a pool, swimming wetsuits provide buoyancy while maintaining flexibility and range of motion.
