The suit covers the skin for modesty. Competitive swimwear seeks to improve upon bare human skin for a speed advantage. For extra speed a swimmer wears a body suit, which has rubber or plastic bumps that break up the water close to the body and provides a small amount of thrust just barely enough to help a swimmer swim faster.
A swim cap keeps the swimmers hair out of the way to reduce drag. Caps may be made of latex, silicone or Lycra.
Goggles keep water and chlorine out of swimmers eyes. Goggles may be tinted to counteract glare at outdoor pools.
