Headstrong™ is made of HDPE which is chlorine resistant and UV resistant. Headstrong™ works for all types of swimming techniques - Freestyle, Breast or Butterfly stroke. Swimmers can also wear the device to provide a focal point... which is especially helpful for doing the backstroke. It was developed for male and female triathletes and swimmers training at any skill level.
It's design uses "range-of-motion" to alert athletes of their head position and is completely undetectable to the swimmer until head position exceeds the recommended posture range.
