Course Outline

Divers wear gloves, hoods, and booties for warmth or for protection against cuts, scrapes, and stings.

  • Gloves: Hands do not have much insulation, and they are susceptible to heat loss. However, do not treat gloves as a license to touch anything you want.
  • Hoods: You can lose up to 75% of your body heat through your head. Select a hood that is not too tight. If the hood is too tight, it can compress the arteries in your neck (the carotids), and this is massively uncomfortable and potentially dangerous. Jaw fatigue is another side effect from a too-tightly fitting hood.
  • Booties: These are necessary when wearing open-heel fins. They are useful during shore-entry dives to protect against cuts and scrapes, hot sandy entries, or hot boat decks.
