Sports equipment is constantly evolving to provide athletes with the best possible performance. Among these clothes, the rash guard , initially designed for water sports then combat sports, arouses the interest of running enthusiasts. Should I wear a rash guard for running ? In this article, we analyze the advantages and disadvantages of wearing a rash guard during a running session.
What exactly is a rash guard?
THE rash guard is a tight-fitting jersey with long or short sleeves which was translated from the English term "rash guard". This type of clothing was originally developed for participants in board sports such as surfing and martial arts, such as Brazilian jiu-jitsu. The main function of the rash guard is to prevent irritation and overheating caused by friction with environmental elements (neoprene suit, surfboard, tatami) and other participants. The rash guard also offers anti-bacterial properties and often benefits from high sun protection.
Benefits of rash guard for runners
Protection against UV rays
The first reason why wearing a rash guard is interesting for runners is its protection against ultraviolet (UV) rays . Indeed, rash guards generally have high UPF 50+ sun protection which effectively protects the skin against the harmful effects of the sun. This is especially crucial for regular runners and endurance joggers who spend long hours outdoors. 
Limit irritation caused by friction
Although originally designed to minimize overheating from water sports, the rash guard also has benefits for runners. The materials used in the manufacture of rash guards reduce the risk of skin irritation caused by friction with clothing or equipment. This feature can be beneficial for those who suffer from discomfort when running especially around the arms and armpits.
Ease of movement and freedom
Due to the stretchy nature of the fabric, a rash guard provides increased freedom of movement during the race. Unlike other types of shirts or tops, the rash guard conforms perfectly to the shape of the body, allowing the runner to move with ease without discomfort or restriction.
Moisture wicking and quick drying
The synthetic material used in the manufacture of rash guards helps to wick away moisture of the skin and dries quickly . This quality is especially beneficial for long runs or jogs in hot weather, where sweat can build up and cause discomfort.
In short, wearing a rash guard for running has undeniable advantages in terms of skin protection, moisture wicking and freedom of movement. However, some runners may prefer other types of clothing more suited to their personal style or budget. It is essential to choose adequate, quality equipment to guarantee your comfort throughout your running session.
