Is it time to invest in a UV swimsuit that will protect you from the sun? Are you tired of reapplying sunscreen while at the pool or beach? Maybe you want to go kayaking, paddleboarding, or surfing and can’t easily carry sunscreen with you.
Opting for a UV women’s swim shirt allows you to protect your skin from sunburns, aging, and skin cancer without the hassle of sticky sunscreen.
First, let’s break down the difference between SPF and UPF. Many people may use these terms interchangeably when shopping for UV-protective swim shirts, but these terms actually refer to totally different forms of sun protection!
SPF vs. UPF: What’s the Difference?
Wondering about what’s the difference between SPF vs UPF? Let’s do a quick overview of the difference:
- SPF. SPF stands for Sun Protection Factor. SPF is a rating system used for sunscreens and other topical products containing sunscreen, indicating how long you should be able to stay in the sun before getting burned.
- UPF. UPF stands for Ultraviolet Protection Factor. The UPF number identifies what fraction of the sun’s ultraviolet rays can get through the fabric. A UPF of 50 which is the maximum rating, only allows 1/50th of the sun’s UV radiation to penetrate the material and reach your skin.
As you can see, it doesn’t really make sense to discuss SPF in terms of swim shirts, as SPF is a rating system that is only applicable to sunscreen – not clothing!
Instead, when evaluating sun-protective clothing like swim shirts, we need to look at the UPF rating.
Higher UPF clothing has a tighter weave of materials and is often pre-treated with ingredients that increase its ability to block UV radiation. It does not wash out.
According to the Environmental Working Group’s sun safety tips, UPF is actually a more reliable form of sun protection than SPF in sunscreen, simply because the majority of sunscreen users don’t apply enough of it, use it incorrectly, or don’t reapply it as often as needed.
The Skin Cancer Foundation notes that more people are diagnosed with skin cancer each year in the U.S. than all other cancers combined, which should be enough of an excuse to buy as much high-UPF clothing as you want.
A piece of clothing with a UPF rating of 50 allows you to stay out in the sunshine longer and gives you the confidence to enjoy what you love to do with the knowledge that you are protecting your skin.
Are UV Protective Swim Shirts Fashionable?
UV swim shirts and other articles of UPF clothing certainly can be fashionable and look very stylish!
However, the primary goal of UPF clothing is to keep you safe from the sun. Any fashion elements are secondary! For this reason, UV-blocking clothing like a women’s swim shirt will often feature:
- Full length sleeves (some will even have thumb holes to protect hands and keep sleeves tightly in place)
- High neck lines (some with zippers for easier removal)
- Performance-based fabric to reduce drag and wick away sweat
- Darker colors (as dark colors tend to absorb more UV than light colors)
- Mesh panels under the arms for breathability
- Swim shorts, skorts and leggings
Some style-focused folks might express annoyance at the fact that so many UV clothing items tend to come primarily in dark colors. Darker colors tend to absorb more UV light than lighter colors. In addition, the more vivid the color, the greater the protection; a bright yellow shirt is more protective than a pale one.
That being said, we’ve found some very colorful, cute, and even sexy swimsuits that will make you feel confident and cool!
Do I Want a Rash Guard or a Swim Shirt?
Many folks new to shopping for UV protective swimsuits get a bit confused between the terms “rash guard” and “swim shirt.”
They both pop up a lot when discussing sun protection in the water. But is there any difference? Yes! Let us explain.
Rash guards or “rashies” get their name from their down-under origin in Australia. They were created to protect surfers from rashes caused by sand caught on waxed surfboards and from chaffing against fast-moving water.
These shirts fit very tightly so that they don’t rub against the skin at all. Most of these shirts have a UPF 50 rating but make sure to check in order to be sure. You’ll find rash guards designed for surfing, snorkeling, and even land activities (although they are primarily made to wear during water sports).
Long-sleeved swim shirts with a UPF of 50 are also great in the water. They usually fit a bit looser than a rash guard and can lift up and float on top of the water if they are too large.
Make sure to look at the sizing charts before purchasing a swim shirt, as they often come in several sizes. These shirts are comfortable and some are also well-suited for sports like tennis, golf, biking, and kayaking.
In a nutshell, swim shirts are looser and designed more for lounging on the beach and light swimming. Rash-guards are skin-tight and are designed to not just provide protection from UV rays, but also to protect the user’s skin from chafing and friction that can result from water sports.

What Are Swim Shirts Made Out Of?
Most women’s swim shirts and rash guards are made from:
- A mix of the above
These are used in order to keep the sun-protective fabric materials lightweight, soft, breathable, quick-drying, and stretchy – all great for swimwear!
Many also contain moisture-wicking material that keeps you cool while also making clothes dry faster once you’re out of the water.
What About Sun Shirts?
You’ll notice that many of the products we detail in this guide are referred to a “sun shirts” as well as rash guards or swim shirts – in fact, many manufacturers will just use these terms interchangeably.
This is because sun shirts and swim shirts are, in fact, essentially the same thing. They are usually made of the same material – lightweight, breathable, moisture-wicking fabric designed to keep the wearer dry while protecting them from the sun.
Most swim shirts can be worn as everyday sun shirts, and vice versa! So don’t stress if some of the naming conventions have you confused.
What to Consider When Shopping for a Swim Shirt
- Sleeve Length. Most swim shirts feature a long sleeve to protect you from the sun as much as possible. However, some swim shirts will come in 3/4 length or even short-sleeves, although full sleeves are the most common.
- Pattern. Most of us don’t just want a swim shirt that fulfills the practical purpose of protecting us from the sun – we want something that looks great too! Luckily, modern swim shirts come in a wide range of bright colors and fun patterns that are far from boring.
- Neck Height. Consider how high you want the neck to be. Most swim shirts feature a high neck line, but if you don’t like this look, you may be able to find a few lower-cut options (although they aren’t common).
- Zipper. Swim shirts will often come with a full, half, or 1/3 zipper. Many others don’t include a zipper at all. A zipper can be nice for when you’re done swimming and want to sit back and unwind a bit. Zipping a swim shirt down a bit also make sit easeir to take off (especially when you’re dealing with a rash guard) Just be careful not to zip the shirt too low if you won’t be wearing a bra underneath!
- UPF Rating. The vast majority of swim shirts detailed here will have a UPF 50 rating. If you’re shopping at home, just make sure to look for a swim shirt with the highest rating possible (for swim shirts, that’s UPF 50).
- Bottoms. Most UV swim shirts are sold as just a standlone shirt. This isn’t a problem, if you already have a collection of swim bottoms at home. But, if you want a full set (or something that matches), look for brands that provide a bottom along with the swim shirt tops.
- Built-In Bra. Some swim shirts will include a built-in bra, while others won’t. The built-in bra is definitly a handy feature, but the pads often get dislodged or moved during wash, so be prepared to re-align them as needed. Some individuals still prefer to wear a sports-bra underneath a swim shirt, even if there is a built-in bra. This is mostly a matter of personal preference.
We’ve all felt the sting of a bad sunburn. No matter how diligent you think you are at applying sunscreen, chances are that the sun will sneak in and get you at some point.
Why worry? Sun protection clothing makes a lot more sense than relentlessly reapplying sunscreen, especially for active people.
Enjoy your summer (and spend a few extra hours outdoors) with the peace of mind that you’re keeping yourself safe from the sun!
