Best Rash Guards for Snorkeling Review

You want to return home from a trip with cool stories and memories, not chafed skin or sunburns. With the help of a rash guard for snorkeling, that can be arranged. Traditionally, rash guards were used by surfers to protect sensitive body parts like their armpits, nipples, and neck from getting rubbed raw against their surfboard.

Now, rash guards are used for numerous sorts of water sports, including snorkeling, due to the SPF protection it provides. There are various designs you can choose from, such as short sleeves or long sleeves, loose fitting or tight fitting, and so on.

One thing to keep in mind is that a rash guard is different from a wetsuit. For example, a rash guard does not have as much protection against the cold, unlike a wetsuit. As a result, rash guards are optimal for warmer waters since it can protect you from the rocks, coral, aquatic life such as jellyfish, and of course, the sun.

Below, we go over what you should look for in a rash guard, provide our recommendations, and answer the most frequently asked questions.

Our Top Picks:

What To Look for in a Snorkeling Rash Guard

UPF

It is incredibly important to protect yourself from the sun, and a rash guard is an excellent way to do that. Whether it is protection from rays directly from the sun or reflected off of the water, most rash guards are designed to provide at least 50 UPF to block the UV rays. If you want to spend the whole day snorkeling, you either need a lot of sunscreen (don’t forget to reapply) or a rash guard.

Materials

Most rash guards are made from a blend of synthetic fibers, but the most common ones are neoprene, polyester, Lycra, or a mix of nylon-spandex. Each material provides varying levels of warmth, breathability, and stretchiness, but the most important deciding factor is how comfortable it feels on you.

Lycra: A Lycra rash guard provides breathability, optimal stretch, and dries quickly.

Neoprene: Though you shouldn’t rely on a rash guard to keep you warm, some do provide a degree of insulation from the cold, and neoprene rash guards are one such type. Furthermore, it is very stretchy and lets you move around freely.

Polyester: If breathability is your main concern, polyester is the right material for you. It can also wick sweat, but unfortunately it lacks the flexibility and stretch of Lycra.

Nylon-Spandex: With a nylon-spandex rash guard, a snorkeler will get an all-around tight fit with decent stretch, quick drying, and breathability.

Tight or Loose Fit

You can choose between a tight or loose fitting rash guard. We recommend tight fitting because it does not cause extra drag, nor will it ride up as easily as a loose fitting one. Those who prefer loose fitting rash guards will need to apply some sunscreen to their lower back as it may get exposed when the rash guard shifts. With a tight-fitting rash guard, it will be easier to wear a wetsuit on top of it as well.

Stitching

Many rash guards use a six-panel construction and flat-lock stitching for the best construction and fit. Some rash guards have over-lock seams, and these could rub and chafe against your skin when you are moving. Look for rash guards with flat seams to avoid any issues with chafing.

Tanks, Long-Sleeve or Short-Sleeve

Tanks and short-sleeves may be used on hot days where overheating may be a concern. You can get more flexibility and freedom of movement, while still getting some protection from the sun.

We prefer long-sleeved rash guards over tanks or short sleeves simply due to the extra coverage it provides. After all, why would you want to expose your arms to the sun, jellyfish stings, abrasions, and so on? If you already made the decision to get extra protection with a rash guard, why not go all the way and get a long-sleeve?

Aesthetics

You always want to look your best, and what better way than by getting a rash guard with awesome designs and artwork on it? This is accomplished in either two ways: heat transfer or sublimation. When buying a rash guard, if you care about how you look, then keep these processes in mind.

Heat Transfer: This method is the cheaper of the two, because it is much easier to do. Think of it like an iron-on graphic. It looks good the first few times you use it, then it will start to peel, crack and fade over time. If you are a casual snorkeler or saving money is your number one priority, then rash guards with heat transfer designs will work just fine for you.

Sublimation: This process is much more expensive than heat transfer. Sublimating a graphic is an arduous process, however the results are worth it. Rash guards with sublimation designs will last longer because the artwork or design is now part of the guard itself. This means it won’t crack or fade through normal use. If you plan on snorkeling frequently and want to look great every time, then look for a rash guard with sublimation artwork.

Gender

Some rash guards have unisex designs, meaning there are both male and female versions. The shape will be different, so make sure you buy the right one for the best fit.

Frequently Asked Questions

Do You Need a Rash Guard to Snorkel?

We highly recommend you wear a rash guard when snorkeling. Unless you already have a wetsuit, a rash guard will protect your back from getting badly sunburnt as you will be spending a lot of time lying horizontally. With all of the sights that you’re seeing, you may easily lose track of time, forget to reapply sunscreen, and get badly burnt.

Aside from protecting you from the sun, a rash guard can also protect you from the underwater environment. Of course you know to stay away from coral, but sometimes accidents happen anyways. Coral is very sharp and some species will give you a bad sting. A rash guard will reduce the damage you take, as well as protect against jellyfish stings and sharp rocks.

For those planning on snorkeling in a cooler climate or for only short periods of time, then perhaps you will not be at as much of a risk of being sunburnt. However, you would still be susceptible to the other dangers, and you will have to carefully track the last time you applied high SPF sunscreen. Honestly, it’s quite the hassle; why not just wear a rash guard and not have to worry about any of this?

Why Don’t I Just Wear A T-Shirt Instead?

Beginners often underestimate the effectiveness of a rash guard, thinking they either don’t need one or that a T-shirt would be an acceptable alternative. It is not. T-shirts provide a negligible amount of protection, only 5 SPF, which is better than nothing but not very good.

Plus, when a shirt gets soaked, that SPF rating gets even lower. If you are exposing your back to the sun’s harmful UV rays for the entire snorkeling session while thinking a T-shirt is adequate protection, you will be in for a painful surprise when your skin starts peeling off.

What Can I Wear with A Rash Guard?

Men can simply wear a rash guard with standard swimming trunks or board shorts. Women can wear a standard bathing suit underneath or the bottom part of a bikini with a rash guard.

How Tight Should a Rash Guard Be?

In order for a rash guard to be effective, you have to make sure it fits properly. Remember that there are loose fitting and tight fitting rash guards. Which type is better for you depends on what you intend to use it for. For example, a tighter fit is better for performance since it will have the least amount of drag in the water.

On the other hand, a loose fit rash guard can reduce your performance since the extra resistance can be cumbersome while swimming. Thus, if you want to swim faster and farther, then your rash guard should fit tight. On the other hand for casual snorkelers who just want some extra UV protection, just get the one you prefer to wear.

Is Sunscreen Still Necessary?

Yes. Rash guards do not cover every square inch of your upper body, especially if you decide to buy a short sleeved one. You will still need to apply sunscreen exposed skin that the rash guard does not cover. For those wearing a loose fitting rash guard, consider applying sunscreen to sections the rash guard may leave exposed if it were to ride up, such as the lower back.

How is a Rash Guard Different from a Wetsuit?

While rash guards do fulfil a similar role to wetsuits for snorkeling, namely protection from the sun or keeping you warm, there is a significant difference. A wetsuit simply covers more of your body and provides more protection, and in really cold water you could even wear a rash guard underneath a wetsuit.

Whether you wear one over the other, or both, depends on the temperature of the climate you are in. If you have to deal with cold winds and cold water, you may be better off with a wetsuit if you could only pick one. A general rule of thumb is, if the water is warmer than 75 degrees fahrenheit, then you don’t need to wear a wetsuit.

The Bottom Line

While it is not absolutely necessary to snorkel with a rash guard, we believe it is greatly beneficial. With one, half of your body will be protected from the sun’s rays, you only have to apply sunscreen to the remaining exposed body parts, and you have some protection against abrasions and stings. A T-shirt is not an adequate substitute because it barely offers any SPF protection. We recommend you get a long-sleeved, tight fitting rash guard for optimal protection.
