Can sports underwear replace swimwear

Can sports underwear replace swimwear? The answer is: No.

Sports underwear and swimwear have different functions and different fabrics. The swimwear is required to be waterproof and elastic. But sports underwear is not only waterproof, but also made of pure cotton fabric with good water absorption, so wearing underwear in the water will make the body sink. Therefore, sports underwear can not replace swimwear when swimming.

Sports underwear and swimwear are very different. The swimsuit should be suitable for underwater sports. This requires that the swimsuit should be waterproof, elastic, and have little resistance to water during underwater sports. In order to achieve this, the swimsuit will be designed into a very tight style. The most important thing about underwear is that it should be comfortable and not too tight, so it is skin friendly, breathable and hygroscopic, and can keep the skin dry at any time.

The material selection angle of swimwear and underwear is completely opposite, mainly reflected in the hydrophilicity of fabrics. Swimming suits are usually made of DuPont Lycra, nylon, polyester and other fabrics with good water resistance and elasticity, while underwear is usually made of pure cotton fabrics with good water absorption. Swimming suits usually use nylon fabric containing 18% elastic fiber, which is quite elastic. However, ordinary underwear does not have such a high demand for elasticity, which is usually 5% – 10%. Swimsuits do not have the breathability and moisture absorption of underwear. Similarly, underwear cannot replace swimwear, because underwear does not have the waterproof property of swimwear, and cotton underwear will become translucent after absorbing water, which is easy to cause embarrassment.

So pay attention to the following points:

1. Do not swim with your underwear as a swimsuit, because the fabric of your underwear is mostly pure cotton, which is easy to absorb water after entering the water, leading to heavy underwear. In addition, your underwear is loose, which is very unsafe. And light colored underpants are more transparent.

2. Swimming trunks should not be worn as underwear. They are not breathable and do not absorb sweat, which is very harmful to health.

3. When purchasing swim trunks, pay attention to the connection between the thread end and the fabric and the fabric to avoid thread splitting or fabric breakage.
