Why Use a Scuba Diving Hood?
When you feel cold in the water, it is uncomfortable and your body functions become affected and start to shut down. Many divers use neoprene wetsuits, booties, gloves, and even drysuits to combat the cold. The addition of a hood can also be very effective as 60% of the body’s heat is lost through the head, so it follows that if the head is warm, it can help greatly in keeping the whole body warm.
Neoprene is a flexible, spongy rubber material filled with bubbles. When used in a diving hood it forms a close fit and traps heat between the head and the hood. The thin layer of water there becomes warm from the body’s natural heat and with a proper fit is trapped, keeping the head warm throughout the dive. If the hood is too loose and isn’t well sealed, cold water from the outside will flow through and the effect is lost.
The colder the water, the thicker the neoprene will need to be. A rule of thumb is that for a water temperature of 70°F (21°C), 1-3 mm is the appropriate neoprene thickness, for 60-70°F (15.5-21°C), 4-5 mm and 50-60°F (10-15.5°C), 6-7 mm.
A cold water hood should cover the forehead, jaw, and chin. A bib helps to eliminate water flow by tucking into a wet or drysuit. If the drysuit has an insulated neck, the bib wouldn’t be needed.
A warm water hood is thinner, without a neoprene bib and generally covers less of the face. For really warm water, nylon, lycra or some other new materials may be used. While doing little to keep the head warm, a lycra hood can provide UV protection and prevent sea lice, stingers, and other irritants from getting to the skin.
As mentioned, the fit should be snug to prevent water flowing in and out, but it should not be too tight. A firm seal around the face and neck without discomfort is desired. The newer versions of neoprene are very stretchy and flexible so that donning and doffing the hood is easy. Some hoods have included a zipper or drawstring to aid in this process and in sealing.

Scuba Diving Hood Care and Maintenance
- Rinse in fresh water after each dive (just like a wetsuit). Don’t machine wash or use detergent.
- Allow hood to thoroughly dry out of the sun in a ventilated place.
- Don’t store it in the direct sun or under a lot of weight to avoid deterioration and deformities.
