Rash guards – or rashies, or rash vests – are a popular choice for those diving in tropical waters. They have their origins in surfing. Surfers began to wear T-shirt-like skins in order to protect themselves against the friction brought about by the salt, sand and board. Since then, rash guards have become a favourite among many people across all watersports. For divers, rashguards present two possibilities. They can be worn alone when diving in tropical waters, or they can be worn underneath a wetsuit in order to increase insulation and reduce water ingress (if constructed with a built-in hood). With the help of our product recommendations and buyers advice guide, you should be well on your way to deciding which rash guard is best for you.

Rash Guard Guide
Rash guards have a variety of benefits for divers wishing for something a little less cumbersome than a standard wetsuit…
Provides maximum freedom – Rash guards allow for freedom of movement incomparable to any other exposure protection. Diving with a rash guard is like diving naked; just without the awkward stares and embarrassment. Given that the majority of rash guards are composed from a mixture of nylon, spandex, polyester or lycra, they are extremely flexible whilst remaining tight fitting to the skin. These materials also result in them being extremely lightweight; perfect for the travelling diver.
Less weight carried – Unlike a wetsuit, which has inherent positive buoyancy, a rash guard is normally neutral. For those usually burdened with numerous blocks of lead, switching to a rash guard will ease that burden significantly. This is a very liberating feeling, especially for those who have never experienced it.
UV Protection – The majority of good quality rash guards are UPF50+ rated (some even go up to UPF 200+). This is great for divers wanting to escape the bulk of a wetsuit whilst remaining protected from the sun. This carries over to other watersports, such as swimming, surfing or SUP. The added benefit of built-in sun protection is a reduced need to wear sunscreen, which can be harmful to coral reef systems.
Prevent chafing – As the name suggests, rash guards act to prevent rashes and chafing. For divers, this will prevent chafing against the BCD as well as protection against stings from jellyfish. This is perfect for those wanting to stay protected whilst enjoying the freedom of wetsuit-less diving. Similarly, a good rash guard is often more comfortable than a cheap wetsuit with overlock stitching.
What to Look for in a Rash Guard
- Long sleeves – For divers, it is best to get a rash guard that comes with long sleeves. This will provide maximum protection against BCD chafing and jellyfish stings, as well as ensuring that your shoulders and arms are covered from the sun during long surface waits. This will also result in increased insulation if used under a wetsuit.
- UV Protection – Not all rash guards are made equally. When purchasing one, be sure to check that it is rated to at least UPF 50+. This will ensure that it delivers actual sun protection, and is an easy way to tell the good rash guards from the bad.
- Material – Lycra and nylon-spandex rash guards are breathable, flexible and quick drying. Polyester rash guards are also breathable and very durable, but are slightly more limited when it comes to stretch – making for a little less freedom of movement than with lycra or nylon-spandex. However, polyester is still an excellent material for rash guards that will be used for diving. Neoprene is less common for rash guards, usually being the material used for dedicated undervests for wetsuit use. But it is still sometimes used for dedicated rash guards too. Neoprene provides the best insulation and is also tight fitting. It is also very flexible. The drawback of a neoprene rash guard, however, is its increased weight/positive buoyancy as well as its slower drying capability.
- Quick Drying – As a rash guard provides little in the way of thermal insulation, it is essential that it is quick drying if it is to be used for repetitive diving. This means that you won’t have to stomach a soggy rash guard everytime you go for your second or third dive.
- Skin tight – Ideally, a rash guard that will be used for diving should be tight fitting. This will minimise water ingress, allowing it to proffer the little thermal insulation it can. Equally, a tight fitting rash guard is streamlined, making the diver as efficient as possible in the water.
