What is a Rash Vest and Its Purpose?
A rash vest, also known as a rash guard, rashguard, or rashie, is a slim-fitting, lightweight shirt made of quick-drying synthetic material designed to block UV rays. Its primary purpose is to provide protection during water-related activities.
Originally popularized by Australian surfers aiming to shield themselves from UV rays, sand, and surf wax, these vests have become a vital accessory for almost all watersports and activities. Rash vests are highly suitable for surfing, kayaking, stand-up paddleboarding, swimming, and other watersports. They offer additional shielding from UV rays and protect the skin from potential abrasions caused by sand and hard surfaces.
For anyone spending time in or near water, rash vests become an essential piece of gear, whether it’s for surfing adventures or lounging poolside to avoid sun exposure.

When to Wear a Rash Vest?
Rash vests are recommended for anyone seeking skin protection against the sun, wind, or water. Whether you’re surfing, paddling, relaxing at the beach, or by the poolside, rash vests prove valuable. If you are surfing they can be worn under a wetsuit for added friction protection or with boardshorts for extra warmth in cold water or windy conditions.
Material Composition of Rash Vests:
The Fabric: Rash vests are crafted from a synthetic poly-elastane blend material, offering several desirable properties. This gives stretchability, durability, quick-drying capabilities, and effective UV-blocking and moisture-wicking abilities.
The snug and close fit of rash vests allows for unrestricted movement and comfort in the water. Many rash vests are designed with chlorine-resistant materials for safe use in swimming pools.
Comfort and durability are ensured through quality construction. Rash vests seems should feature flatlock stitching, where each fabric piece is sewn together without overlapping. This technique prevents bulkiness, enhances seam strength, and reduces chafing.
Some swim shirts and surf shirts boast similar materials and technologies as rash guards but offer a more relaxed fit, resembling a regular t-shirt. They are designed for optimal comfort and unrestricted movement during water activities.
UV Sun Protection Provided by Rash Vests
The main advantage of wearing a rash vest is UV protection.
While sunscreen lotions are rated by SPF, rash vests are rated by UPF (Ultraviolet Protection Factor). A rash vest with a UPF of 50 means only 1/50th of the sun’s UV rays reach the skin. With a rash vest, you can enjoy continuous sun protection throughout the day without the need to frequently reapply sunscreen to the covered areas.
When choosing a rashie, it is essential to check the specifications of rash vests to ensure they offer good UPF protection. However, it is still recommended to apply sunscreen to areas not covered by the rash vest.
Is a Rash Vest a Base Layer?
Rash vests should be worn as a base layer, eliminating the need for additional clothing underneath. If worn under a wetsuit, it is crucial to ensure a snug fit.
In warm water conditions where a wetsuit is unnecessary, rash vests can be paired with favourite boardshorts. Depending on personal preferences for coverage and sun protection, rash vests are available in both long and short sleeve options. Hooded rash vests are also available for added sun and wind protection.
