Rash vest

Rash vest (also known as a rash guard or rashie) is a type of athletic shirt made of spandex, polyester, nylon, or other synthetic materials. It is designed to protect the wearer's skin from irritation caused by rapid impact with surface water and waves and from sunburn due to extended exposure to the sun's ultraviolet (UV) rays.

History

The rash vest originated in Australia where it was initially used by surfers to protect against chafing caused by the wax on their surfboards. The wax would often cause a rash on the chest and stomach area of the surfer, hence the name "rash vest". Over time, the use of rash vests has expanded to various water sports including swimming, snorkeling, and scuba diving.

Design and Use

Rash vests are typically made of elastane, also known as spandex, or a blend of other synthetic fibers. They are designed to be quick-drying and are generally lightweight, durable, and resistant to salt water and chlorine degradation. Rash vests are most often worn as a standalone piece, but can also be worn under a wetsuit for additional comfort and protection.

Rash vests provide protection from the sun's harmful UV rays. Many rash vests offer a Ultraviolet Protection Factor (UPF) of 50+, the highest rating available. This means that the fabric blocks 98% of the sun's harmful rays, reducing the risk of sunburn and long-term skin damage.

In addition to sun protection, rash vests also provide a barrier between the wearer's skin and potentially harmful elements in the water, such as jellyfish stings or minor scrapes and cuts from rocks and coral.

Variations

There are several variations of rash vests, including short and long-sleeved versions, and those with a high neck collar. Some rash vests also include a board short connector loop at the bottom hem to prevent the vest from riding up during active water sports.
