A rash guard (also known as a rashie or rash vest) is a fitted top made from polyester, nylon and spandex which is typically used during water sports such as surfing, paddle boarding, kayaking, swimming or kite surfing. It is also common to wear a rash guard to the beach or by the pool on holiday. 

The origins of rash guards are unclear but are thought to have been invented in Australia for use during surfing. Variations of rash guards have since been adapted for other sports like American football and baseball as a base layer.

One of the benefits of rash guards is to minimise skin irritation due to chafing. Rash guards reduce the risk of chafing because they are fitted garments. The risk of chafing is also reduced because they are usually constructed with flat lock seams, tend to be moisture wicking and utilise fabrics which also help regulate the body temperature.

It is important that rash guards provide UPF 50+ sun protection

Rash guards can also be effective as sun protective clothing. With the right fabrics, rash guards can be rated UPF 50+ which provide excellent sun protection. UPF 50+ rating means that at least 98% of UV radiation is blocked.

Sun protection is particularly important whilst participating in water sports as it involves being outdoors for a prolonged period of time. UV reflects off the water and sunscreen may be less effective when a person perspires or has spent some time in the water. 

Rash guards are also popular for use during water sports and sporting activities in general because they utilise fabrics which are quick drying.
