Common swimwear
Brands such as Arena, Speedo, TYR, and Adidas are popular regular swimwear brands. The most durable material for regular swimming is Polyester. The main difference between competition and regular swimwear is that competition swimwear is tighter and compresses the muscles of the swimmers. Regular swimwear is easier to put on and more comfortable for leisure activities.

The most used practice swimwear for men includes briefs and jammers. Males generally swim barechested.
There was controversy after the Beijing Olympic Games in 2008 when many Olympic swimmers broke records an unprecedented number of times using revolutionary swimsuits that covered their entire legs. To highlight the issue, in 2008, 70 world records were broken in one year, and 66 Olympic records were broken in one Olympic Games (there were races in Beijing where the first five finishers were swimming faster than the old world record).
As of 1 January 2010, men are only allowed to wear suits from the waist to the knees.^[24] They are also only permitted to wear one piece of swimwear; they cannot wear briefs underneath jammers. This rule was enacted after the controversy in the Beijing Olympics and Rome World Championships.
Women
Women wear one-piece suits with thicker and higher backs for competition, though two-piece suits can also be worn during practice. Backs vary mainly in strap thickness and geometric design. Most common styles include: racerback, axel back, corset, diamondback, and butterfly-back/Fly-Back. There are also different style lengths: three-quarter length (reaches the knees), regular length (shoulders to hips), and bikini style (two-piece). As of 1 January 2010, in competition, women must wear suits that do not go past the shoulders or knees.
Use of drag wear
Drag suits are used to increase water resistance against the swimmer to help them train for competitions. Other forms of drag wear include nylons, old suits, and T-shirts: articles that increase friction in the water to build strength during training, and thus increase speed once drag items are removed for competition. Some swimmers practice in basketball shorts over their bathing suit, wearing two bathing suits, or wearing an extra bathing suit with holes cut in the material.
Many swimmers also shave areas of exposed skin before end-of-season competitions to reduce friction in the water. The practice gained popularity after the 1956 Olympics, when Murray Rose and Jon Henricks came shaved and won gold medals for Australia.^[25] Freshly shaven skin is less resistant when in the water. In addition, a 1989 study demonstrated that shaving improves a swimmer's overall performance by reducing drag.^[26]
The disadvantages of using a drag suit include the depletion of proper stroke. This is caused by the swimmer's own fatigue. When the swimmer becomes more fatigued, different muscle groups become more tired
