Caps made of latex are stretchy, so they fit most heads. Take care when wearing or removing, as latex swimming caps can “grab” long hair, and pulling your hair is uncomfortable.

In a warm environment, latex swim caps can increase a swimmer’s body temperature because they are non-porous.

Between the cap and the scalp, they trap a layer of warm water, which protects the swimmer from the cooling water in the pool. It is important to keep in mind that some swimmers have an allergic reaction to latex.
