Best Rash Guard

Rash guards were originally developed for surfers. Paddling out on a surfboard can cause a friction rash and, if you are out on the water long enough or often enough, this can get really painful and unsightly.

Rash guards provide protection from friction, the water, and, more often, the sun too. But which is the best rash guard to buy?

With so many different manufacturers and designs to choose from, it can be hard to know where to start.

In this review, we’ve tried and tested the 12 most popular rash guard shirts so you can make an informed choice.

We’ve included well-known and lesser-known brands, models made for men and women, long and short-sleeved models, and a range of fits too. Whatever type of rash guard you want, we’ve got you covered.

Avoid painful rashes and potentially dangerous sunburn, and wear the best rash guard for your needs.

3. Speedo Men’s UV Swim Shirt

Most rash guards and vests fit like second skins. However, while form-fitting designs can be appealing for some, others prefer a looser fit. This swim shirt from Speedo isn’t fitted and looks quite casual, making it ideal for those who prefer a more relaxed cut and fit.

4. NRS H2Core Women’s 

Rash vests can be a struggle to put on and take off. Plus, once you are wearing yours, if you start to get hot, it’s not easy to regulate your temperature. This guard from NRS addresses both these problems to make a functional and good-looking shirt for women.

Key Features

• Long sleeves
• Strategically placed seams
• Low profile quarter-zip at the front
• Moisture-wicking, breathable material

Pros

• Easier to put on and take off than many other rash guards
• Very comfortable
• Perfect for swimming and paddling
• Very well made

Cons

• Quite expensive

This isn’t the cheapest rash guard you can buy, and it’s only available in two plain colors, but the zip adds some extra functionality, which makes this model very popular and highly recommended.

5. O’Neill 24-7 Traveler

This shirt is not strictly a rash guard, but that doesn’t mean you can’t wear it as one. Instead, it’s a technical T-shirt with a very high UPF rating that’s at home on dry land as well as the sea. It’s cut for comfort, so you’ll be happy wearing this at the beach bar or out on your board.

Key Features

• 93% nylon/7% elastane for a relaxed, flexible fit
• Short sleeves
• 11 colors
• Six sizes, from small to XXXL
• UPF 50+

• Fits like a regular T-shirt

This product is called the 24/7 shirt because you can, in theory, wear it 24 hours a day, seven days a week. It’s at home on the beach, in the bar, and out on the water. And, because it’s light and fast-drying, it’s also perfect for travel. It’s a great do-it-all shirt.

Pros

• Wear for any activity – water-based or on dry land
• Light and comfortable
• Relaxed fit
• Good range of colors
• Well-priced

Cons

• Users report that these shirts run a little small

Because they aren’t very stretchy, these shirts aren’t very forgiving if you buy a size too small. For that reason, it may be worth buying one size bigger than usual, so you have room to breathe and move. But, once you have got the right size, this shirt is as practical as it is comfortable.

6. Kanu Surf Men’s

Pros

• Very well priced
• Light, breathable, and quick-drying
• Good range of colors and sizes
• Relaxed fit

7. O’Neill Basic 

While long sleeve rash guards over excellent protection from the sun, they can get a little warm. Some people also find them restrictive. This shirt from O’Neill has short sleeves, so you’ll stay cooler and enjoy freer upper body movement. Just don’t forget to put some sunscreen on your arms!

Pros

• Cool and comfortable
• Practical design
• Easy care fabric

Cons

• Some users report that this product runs a little small

Pros

• Proven design

9. Billabong Women’s Long Sleeve

Rash guards come in a range of colors, but many are very plain. They’re made to be worn under a wetsuit, so it doesn’t matter much what they look like.

12. RVCA Men’s Short Sleeve

RVCA men’s short sleeve rash guard is a classic, slim-fit design that should appeal to anyone who spends time on or in the water. Understated, this guard is ideal for wearing under a wetsuit, but can also be worn on its own. Snug but unrestrictive, this guard is perfect for energetic watersports.

Key Features

• Comfortable
• Breathable and fast drying
• Well-priced
• Machine washable

Cons

• Some users report this product runs a little small

This short-sleeved rash guard will protect you from the sun and sea, but it’s equally at home in the gym or out on the running track. Some users wear this product for Brazilian Jiu-Jitsu, so it’s clearly made to last. A few more colors would be nice, but apart from that, this rash guard is a good buy.

Bottom Line

The right rash guard can add a lot to your time on or in the water. It will provide a barrier between you and any equipment you are using, reducing friction, and preventing irritation. They’re especially useful for things like paddling out on a surfboard, kayaking, and paddleboarding.

You can also wear a rash guard under your wetsuit, to provide an extra layer of insulation, and also protect you from rubbing under your arms and around your neck.

Most rash guards offer sun protection too. Sunscreen creams and lotions are fine, but can wash off, and need to be reapplied frequently. They can also make you sweat and your skin slippery. With a UPF of 50+, rash guards can protect you from the harmful rays of the sun.

The best rash guards are light, breathable, flexible, and very comfortable. Available in a range of designs and fits, with long or short sleeves, and to suit most budgets, you should have no problem finding the right rash guard for your needs.
