Rash Vests

Rash Vest FAQs

What is a rash vest? 

A rash vest is a lightweight, stretchy top made from materials like lycra or polypro, designed to add comfort and protection in the water. For colder conditions, you can also choose thermal rash vests, which provide an extra boost of warmth under your wetsuit.

Worn underneath a wetsuit, a rash vest helps prevent irritation and rubbing, keeping you more comfortable during longer sessions. It can also be worn on its own as a top, offering valuable UV protection when you’re out in the sun.

Whether you’re looking for added warmth, extra comfort, or sun protection, a rash vest is a simple upgrade that makes a big difference in and out of the water.

How should a rash vest fit? 

A rash vest should fit snug, almost like a second skin. This close fit stops it from rubbing, keeps it comfortable under a wetsuit, and ensures it doesn’t trap excess water. It shouldn’t feel uncomfortably tight or restrict your movement, but it also shouldn’t be loose — a baggy rash vest can ride up under your wetsuit and become distracting in the water.

The right fit gives you smoother movement, better comfort, and reliable protection, whether you’re wearing it on its own or under a wetsuit.

What is the difference between a rash vest and rashie?

There’s no difference at all — a rash vest and a rashie are simply two names for the same item. You may also hear it called a rash guard. All three terms refer to the same protective, stretchy top designed for comfort, warmth, and UV protection in and out of the water.

Can a rash vest be worn for sports other than surfing?

Absolutely - rash vests are incredibly versatile and can be worn for a wide range of watersports, including bodyboarding, paddle boarding, kayaking, and open‑water swimming. Their lightweight, quick‑drying design makes them ideal for any activity where comfort, protection, and freedom of movement matter.

Here at St. Vedas Surf Shop, we even wear our rash vests for field sports like hockey or rugby, using them as a warm, flexible base layer on colder days. They’re a brilliant all‑rounder both in and out of the water.
