History
Swim caps were made of rubberized fabric during the early 20th century. By the 1920s, they were made of latex. The earliest chin strap caps were known as "aviator's style caps" as they resembled the strapped leather helmets of flyers of the day. During the 1940s, swim caps became scarce as rubber was needed for war materials. The

A permanent wave, commonly called a perm or permanent (sometimes called a "curly perm" to distinguish it from a " straight perm"), is a hairstyle consisting of waves or curls set into the hair. The curls may last a number of months, hence the ...
hairstyle took time to obtain and was expensive, so many women wanted to protect their hair while swimming. The 1950s saw decorated caps come into vogue, and during the 1960s, colorful flower petal swim caps became popular. Men's long hair styles of the late 1960s and early 1970s gave rise to increased use of swim caps. Without swim cap requirements, wearing swim caps fell out of fashion during the 1970s. Swim caps are available in different styles: the traditional chin strap type with inner sealing to keep out water and colorful floral styles reminiscent of the 1960s as well as other graphic prints.
Recently, Toks Ahmed and Michael Chapman created a swim cap specifically designed for dreadlocks, hair weaves or extensions, and voluminous hair. They named it the Soul Cap, but it was banned at the

Double capping
Many swimmers have trouble finding a swim cap that keeps their hair dry. "Double capping"—wearing two swim caps—can provide a tighter swim cap seal. An inner silicone or latex swim cap pulled low over the ears worn under a second traditional style chin strap swim cap with an inner seal may provide the protection desired. "Double capping" is also used by participants of

In order to make as smooth a surface as possible for maximum streamlining, sometimes an inner latex cap is put on, followed by swim goggles over the latex cap, and then second snug silicone swim cap is fitted over both.

Several other long distance swims such as the Santa Catalina Channel California swim have similar rules for record swims. Swim caps worn for open water swims should be of visible colors that contrast with the water so that observers may safely monitor them, and operators of vessels may see them.
