Best Rash Guards

Skin irritation and other conditions linked to it are among the most common issues encountered by water sport enthusiasts. This could be the result of rubbing your skin constantly with your surfboard or prolonged sun exposure when you are out kayaking.

Fortunately, the best rash guards are now accessible in the market. Just like comfortable pajama for men, a good and reliable rash guard serves as the ultimate solution for comfort and protection whenever you are in the water.

However, it is not advisable to buy just any product being offered to you. Just like when you are hunting for the world’s best silk boxers, or any other product for that matter. Shopping for these items should be done carefully and mindfully.

What Are Rash Guards

Also called a rashie or rash vest, a rash guard refers to an athletic shirt usually constructed from polyester or nylon and spandex materials. It got such a name because it can indeed guard you against rashes triggered by abrasion and sunburns caused by prolonged sun exposure.

You can wear this protective athletic shirt by itself or beneath a wetsuit. The main goal of wearing them is to get light coverage when dealing with mild to extreme temperatures during the summer. This is specifically when you perform any water sports like surfing, scuba diving, windsurfing, wakeboarding and snorkeling.

Just like the fact that chukka boots can be worn with everything, the rash guard also has that flexibility because you can wear it in a wide range of watersports.

Benefits of Wearing Rash Guards

Wearing rash guards can produce several incredible benefits. The following are the most notable ones:

If you are already tired of getting your skin sunburned when trying to enjoy the sea or some water sports, then you can always choose to wear a rash guard.

A rash guard works based on its primary goal of protecting surfers from abrasions triggered by waxy and sand residues found on their surfboards. The usual rash, in this case, often takes place with the constant sliding off and on a rough surfboard.

However, it is not their only function. They also work by protecting wearers, especially children, when trying to enjoy the water or the beach. It often features a lightweight and quick-drying material as well as flat-lock stitching that helps ensure that it works in assisting wearers to endure a comfortable and enjoyable time at the beach.

Types of Rash Guards

Rash guards are available in various types and styles. You can find those made primarily to protect you against rash while others protect sensitive parts of your body, like your nipples, necks, and armpit.

Standard Rash Guard

You can go for the standard rash guard, which can come in the form of a vest or a long- or short-sleeved rash. Your choice here should depend on where you intend to use it and your personal preference:

Long-Sleeve Rash Guard

This refers to a simple and fitted rash guard or shirt, which mainly covers your shoulders. It also provides additional insulation beneath a wetsuit. With that, expect it to work well even when worn alone in warm climates

Tank or Vest

This is ideal in areas with temperate climates. It is because it does not cover your arms nor shoulders. It also works great because of the additional insulation it provides beneath a wetsuit. It is suitable for anyone who does not want to feel like their shoulders and arms are restricted due to the rash guard.

Full-Body Rash Guards

You can also go for a full-body option made using the materials that were also often used in other standard versions. One thing that makes the full-body rash guard variation different is that it is designed in a way that it works like a wetsuit. This makes it capable of providing more protection for your legs and pelvic area.

You can often find this being used in several ocean sports. You can choose to wear it on its own or beneath a wetsuit. While this one is completely protective, many still complain about it being restrictive of their movements.

Materials of Rash Guards

Just like when searching for the best robes for men or the most comfortable and durable suspenders, you can also see different materials being used in constructing the rash guard. Among the most common ones are:


Most rash guards are made of Spandex. This is good for those who want theirs to be stretchy, quick-drying, and breathable.


You can also go for the polyester-based ones that do not only provide maximum breathability but also boast of their sweat-wicking ability. The only problem with polyester is that it is not as flexible and stretchy as other materials.


Rash guards constructed from nylon material usually have the same qualities as Spandex. These include being stretchy, quick-drying, and breathable. The combination of nylon and spandex can also give you a tight yet comfortable fit.


If you want to receive more insulation, then you can always benefit from the neoprene-based itemss. This material can provide insulation to your body, especially if you are in cooler waters. Aside from that, it is stretchy, promoting flexible and non-restrictive movements.

Of course, you also need to find the appropriate fit. One thing to remember regarding the fit, though, is that this product needs to fit tightly to your body. This is necessary for preventing chafing or uncomfortable rubbing. However, you can also find products that are slightly looser to ensure that these won’t make those who are conscious of their body feel uncomfortable.

Sun Protection

Make sure that the item you buy can protect you from the sun. Note that you will be exposed to the sun’s rays that are somewhat damaging. Have some form of protection with an item that boasts of a high level of sun protection.

The good thing about rash guards is that they are available in various styles, so you will always be able to get one that meets your preferences and sense of style. You can also choose to put some exciting designs and artwork through heat transfer or sublimation.


Assess the price of each rash guard, too. Make sure that you don’t spend too much without analyzing if the price also corresponds to its quality. Your goal is to find one that offers superior protection and compression while remaining reasonably priced. You can compare the prices of your options and check their individual features, so you will know which one is worth it.

You need to size a rash guard properly if you want it to fit you comfortably and correctly. Here are the actual steps in sizing it:

Step 1 – Choose between a tight or loose fit

In this case, you have to determine the specific activity where you intend to use it. If your activities often require movements, such as when you are surfing or swimming, then go for a tight-fitting item. It is because this fit is less resistant and capable of lessening the risk of rubbing and chafing.

However, if your goal is to use the product to serve as the ultimate means of protecting yourself from the sun, then going for a loose fit already helps. The loose fit can make you feel comfortable.

Step 2 – Pick the length of the sleeve

Choose a long-sleeve if you plan to use it in cold conditions so you will still feel warm. It also protects you in extremely sunny conditions as this can give you enough protection.

If you want to feel cooler in extremely hot conditions, though, going for the short-sleeved ones is more beneficial. Your decision between the long and the short sleeves, though, should depend on the level of your comfort and the kind of activity you intend to do.

Do’s and Don’ts With Rash Guards

Note that excessive tightness might only cause the seams of the garment to rip and get pulled. This will eventually lead to issues in wear and longevity.
  • Do not ball up or fold the garment – It is because this might cause the fabric to become weak.
  • Wash the rash guard by hand – Avoid washing it in the washer as much as possible. However, if you can’t avoid washing it in your washing machine, make sure to put it in a mesh bag first. Set the washer in a gentle cycle, too.

  • Avoid coming close to chemical solvents, aerosols, gasoline and oil – It is because the stains in these items are not that easy to remove. They might also cause the fabric to become weak.

Does More Spending Mean More Quality

No, a higher price tag does not immediately mean that the product is of top-notch quality.
