Keep reading as below we’ll be reviewing each of these in detail, so you can pick the very best rash guard for you.

What Is A Rash Guard?

A rash guard, also known as a rashie, rash vest, or swim shirt, is a lightweight, stretchy shirt designed specifically to be worn for in-water activities.  They can be worn on their own or layered underneath a wetsuit.

Rash guards are usually made from either lycra, spandex, nylon, neoprene, or polyester. And typically come with either long or short sleeves.

Depending on the specific features, a rash guard can provide sun protection, thermal protection, and of course, rash prevention.

Rash guards were originally worn by surfers to protect them from friction rashes caused by their boards, hence the name. But now these versatile tops have become a staple piece of kit for a wide range of water sports.

Although all of these rash guards are versatile enough to be used for pretty much anything, we’ve split up our list into different categories and activities to make it easier for you to choose.

Things To Consider When Choosing A Rash Guard (FAQ)

Now you know what the best rash guards are, let’s take a closer look at what to consider when buying a new rash guard.

How Should A Rash Guard Fit?

A rash guard should be tight, fitting nice, and snug against your body.

Men's Rash GuardIf a rash guard is too loose it’ll cause unnecessary drag in the water and won’t be able to offer any warmth. 

Plus it’ll get all bunched up if you layer it underneath a wetsuit.

Although, if a rash guard is so tight that it restricts your movement, you should probably opt for the next size up.

However, if you really don’t like to wear tight clothing, especially at the beach, then a looser rash guard will still provide a decent level of protection.

Level Of Sun Protection

All rash guards will provide you with sun protection. But depending on the thickness and construction of the material, the level of sun protection will vary significantly.

If maximum sun protection is a priority then look for a rash guard with a high UPF (Ultraviolet Protection Factor). The UPF rating indicates how much UV radiation, both UVB and UVA, the rash guard allows to reach your skin.

Does A Rash Guard Keep You Warm?

The majority of rash guards don’t keep you warm. As we mentioned above, rash guards were originally created to prevent friction rashes and abrasion, not provide thermal protection.

If you want a rash guard that keeps you warm, choose one that’s made from neoprene and/or a fleece-like material.

The thicker the rash guard is, the warmer it’ll be. Typically rash guards will range from 0.5mm thick al the way up to 4mm.

If you’re snorkeling or diving, you might prefer the ease of wearing a rash guard over a full wetsuit to keep you warm.

Or it can be wonderful to have that little extra layer of warmth underneath your wetsuit. Especially if you’re making multiple dives per day like on a liveaboard.

Don’t forget if you’re scuba diving, a neoprene rash guard will affect your buoyancy. So you might need to take a little extra weight.

No idea how much weight you need for diving? Check out our weight calculator.

Long Sleeve Or Short Sleeve Rash Guard?

This one is really up to you. Obviously, a long sleeve rash guard will give you more sun protection. However many people hate wearing long sleeves when it’s hot.

If it’s a particularly thick rash guard, one that offers great thermal protection, then long sleeves can feel a little restrictive on the arms and shoulders.

Additional Rash Guard Features

Rash guards often feature some very handy extras that are worth considering. For example, thumb hooks are incredibly useful for keeping your rash guard in place as you slide into your wetsuit.

Or perhaps you find rash guards often roll up your torso?

Board short connectors are what you need! These are basically little loops at the hips that help keep the rash guard in place. Or opt for a full bodysuit.

Looking for some extra sun protection?

A rash guard with a hood is ideal for covering your head and neck. As well as helping keep your hair out of your face when swimming.

You can even find pockets in some rash guards!

Still not sure which one to choose?

Ultimately, rash guards are a great sunscreen alternative. The best rash guard for you is the one you feel most comfortable in.

Whether that’s one that’ll keep you warm and cozy, one with the highest sun protection or, simply the rash guard that has the most flattering fit.

All of these top rash guards are versatile, comfortable, and long-lasting. So it just comes down to your budget and what features you prioritize.
