JINTN Neoprene Wetsuit Dive Hood 1MM Scuba Hood Surfing Hat Thermal Dive Hood Water Hood Swimming Caps Diving Hat for Men Women,Black,L

Cheap and cheerful but does the job. Used for caving only so can't comment on suitability for other sports. Thin and slightly loose fit on an XL, a L may be better for my head... But keeps head warm, not sure it would be thick enough for prolonged exposure to cold UK waters.

for what I need it for it is perfect, ( warm water diving), as I am with out hair, it is good to keep the sun off my head when on the surface, and just enough warmth when diving.

I wasnt expecting much due to the price. this really works and keeps you warm despite the wind and cold water

It is exactly what I was looking for.
