Types of Chafing

1. Skin-on-skin chafing: improper stroke mechanics can cause chafing as can a cross-over kick or breathing.
2. Fabric-on-skin chafing: a swimsuit, goggles, swim cap, protective suit (e.g., stinger suit, or wetsuit can cause some mean chafing.
3. Hair-on-skin chafing: facial and body hair can cause chafing.
