Some swimsuits are designed specifically for swimming competitions where they may be constructed of a special low resistance fabric that reduces skin drag. Most competitive swimmers wear special swimsuits including partial bodysuits, racerback styles, jammers and racing briefs to assist their glide through the water thus gaining a speed advantage.
For diving in water temperatures above 25 °C (77 °F), special bodysuits called " dive skins" are worn. These suits are made from spandex

and provide little thermal protection, but they protect the skin from jellyfish stings, sunburn, and abrasion. This kind of suit is also known as a 'Stinger Suit'. Some divers wear a dive skin under a wetsuit, which allows easier donning and (for those who experience skin problems from neoprene) provides additional comfort.
Unlike regular swimsuits, which are designed mainly for aesthetic appearances, swimsuits intended to be worn during competitions are manufactured to assist the athlete in swimming competitions. They reduce friction and drag in the water, increasing the swimmer's forward motion efficiency. The tight fits allow for easy movement and are said to reduce muscle vibration, thus reducing drag. This also reduces the possibility that a high-forward dive will remove a diver's swimwear. Starting around 2000, to improve the effectiveness of the swimsuits, engineers have taken to designing them to replicate the skin of sea-based animals, sharks in particular.

voted to ban non-textile (non-woven) swimsuits in competitive events from 2010. The new policy was implemented to combat the issues associated with performance-enhancing swimsuits, hindering the ability to accurately measure the performance of swimmers. Subsequently, the new ruling states that men's swimsuits may maximally cover the area from the navel to the knee, and women's counterparts from the shoulder to the knee.
Some swimmers use a specialized training suit called drag suits to artificially increase drag during practice. Drag suits are swimwear with an outer layer of looser fabric – often mesh or nylon – to increase resistance against the water and build up the swimmer's endurance. They come in a variety of styles, but most resemble a looser fitting square-cut or swim brief.
History
The history of competitive swimwear has been dominated by concerns over public nudity in the first half of the 20th century and by efforts to reduce water drag in the second half.

Drag suit

A drag suit is a pair of baggy square-cut or brief-style trunks that competitive swimmers may wear over their normal suit to provide extra resistance ("drag") from the water. This allows the swimmer to get more out of their training than they would without a drag suit. Drag suits are meant to be worn over a long period of time to wear in the material and possibly tear the fabric. The more worn-in, torn or ripped the drag suit, the more resistance it provides the swimmer. Since drag suits make swimming more difficult, swimmers do not wear drag suits in competition. Drag suits originated as older swimsuits at the end of their useful life that swimmers would then wear over another suit.

A jammer, also called a swim jammer, is a style of
swimsuit worn by male swimmers, used mainly in competition to obtain speed advantages. They are generally made of nylon and

blend. They typically sit low on the waist and high on the thigh, but provide more coverage for the upper leg than briefs. The square-cut style was popular as a recreational swimsuit for men during the 1950s.
Suits of this type are named for the coverage that they provide to the upper thighs due to a square seam opening for the leg. Square leg suits range in appearance from those similar to swim briefs with a slightly straighter front and wider side panelling (eliminating the arc appearance on the leg), to those resembling
boxer briefs by providing an inch or more of fabric coverage over the upper section of the leg.
The square leg suit of the 1970s made a fashion revival in Australia in 2002 with the introduction of colorful floral and retro geometric patterned suits by swimwear label
Funky Trunks. The style is popular amongst competitive swimmers for pool training and for recreational swimmers in the pool and at the beach.
