Rash guards are one of the best ways to protect yourself from the elements (sun, water, sand) when out on the water. These fitted, athletic shirts come in both short and long sleeve versions and are worn over a normal bathing suit top (for women) or like a swimming shirt for the guys.

Did you know that rash guards and swim shirts aren’t only for surfers? Some of the best rash guards will provide protection from the sun, rashes, and scrapes whether on land or in the water.

They are designed to dry fast and wick moisture, like sweat, away from the body while remaining lightweight and breathable. If you also want to cover up for modesty, rash guards are a great solution.

Throughout this article, you’ll notice that we refer to the UPF (Ultraviolet Protection Factor) of these products. UPF is the rating given to clothing and fabrics that protect you from the sun’s harmful rays. A UPF rating of 50 means that only 1/50th of the sun’s harmful UV rays can get through that particular fabric.

Best Women’s Rash Guards

#1 – CharmLeaks Women’s Long Sleeve Rash Guard

best rash guard for womenCharmLeaks’ long sleeve rash guard for women provides UPF 50 broad-spectrum sun protection. It comes in eight fashionable colors and sizes ranging from small to XX-Large. The patterns and color block striping and fitted shape of this rash guard give it a stylish look, whether you’re hanging out by the pool or out on the water.

This high quality rash guard is made from polyester and spandex. You can expect it to dry quickly and wick away moisture to help you stay cool. It also holds its shape and color well, even with repeated hand washing. We love the soft feel of this shirt and find that it’s perfect for everything from swimming, snorkeling, and kayaking to yoga and cycling.

Owners of the CharmLeaks swim shirt find the 4-way stretch fabric to be extremely comfortable against the skin. The flat-lock seams are smooth and don’t cause any chafing. And, the banded crewneck isn’t constricting, even when the shirt is wet.

Like most rash guards, this shirt is designed to fit snuggly, so it doesn’t constrict movement when it’s wet. If you prefer a looser fit, you’ll probably want to order a size larger than you normally wear.

Note that this shirt does not come with a built-in bra. You will need to wear a lightweight sports bra or swimsuit top underneath.

swim shirt for womenIf you’re a woman who prefers a short sleeve rash guard with a comfortable fit, check out BodyGlove’s Smoothies In Motion line. This rash guard comes in 18 fashion colors and sizes from X-Small to X-Large. It comes with built-in UPF 50+ broad-spectrum sun protection, too.

This rash guard / swimming shirt for women is made from nylon and spandex, so it dries quickly and wicks moisture away from the skin to keep you cool. It fits like a fitted T-shirt, so it’s flattering when dry, but not too loose or too tight when it’s wet. It’s very stretchy and lightweight, making it perfect for swimming or yoga, and everything in between.

Keep in mind that this rash guard tee is meant to be worn over a swimsuit top, so it does not come with a built-in bra. Unfortunately, we did notice just a little bit of show-through when the shirt is wet, but only if you wear a dark color underneath a light-colored style.

This is one of the softest, most comfortable rash guards on the market today. It has a very forgiving, stretchy fit that holds its shape in the water. If you’re a woman who wants cover and comfort at a reasonable price, BodyGlove’s Smoothies In Motion rash guard is exactly what you’re looking for.

The loose fit and soft fabric make it a great choice for all sorts of water sports, as well as land-based sports like cycling and golfing. The fit is similar to a regular t-shirt and is true to size.

As with most rash guards, O’Neill’s is designed for a snug fit that won’t hinder movement in the water. You can simply order a size or two up if you prefer a looser fit. The shirt is made from polyester and elastane, so it dries fast and is silky smooth on the skin to prevent chafing.

Owners of this rash guard tee say that it wicks moisture away from the body to help you stay cool on a hot day. They also report that the sun protection is reliable and even protects the back from sunburn after hours of snorkeling. However, the collar sits low, so you’ll still need to apply sunscreen on the back of your neck.

Unfortunately, some reviewers did report that the sizing is inconsistent with this product. If you’re counting on it for a vacation or specific event, we recommend allowing some extra lead time when ordering in case you need to exchange it for a different size.

We find this shirt to be the best men’s rash guard shirt for those looking for a snug fit, good value, and full sun protection!

FAQs

Does a Rash Guard Keep You Warm?

Rash guards are made to dry fast, but they do not generally provide a lot of extra warmth. If you are looking for something to keep you warm in cold or very cold water, look for a wetsuit or drysuit.

Should I Get the Long Sleeve or Short Sleeve Type?

It really just comes down to personal preference, but a long sleeve version will provide more protection from the sun and rashes and scrapes than a short sleeve one will. You’ll still need to apply sunscreen or sunblock but there will be less to apply with a long sleeve rash guard.

Can a Rash Guard Be Used For Non-Water Activities (ie: Running, Hiking, or Biking)?

Absolutely! Rash guards are designed to dry fast and wick moisture away from the skin, so they are great for any activity that involves sweating.

Consider purchasing a rash guard for each member of the family! The sun protection and comfort are well worth the investment.
