I’ve Been Running in a Sun Shirt and Wow, You're Missing Out
I knew that other people ran in sun shirts, but I never thought running in a sun shirt was for me. Long sleeves on a hot day? No thanks. Instead, I coated my arms, neckline, and back in sunscreen, and cringed as it mixed with sweat during my run and turned into a gross, drippy slime. I sometimes missed a spot, and enjoyed patches of sunburn on my shoulder blades. Just comes with the summer running territory, right? And then, one day, I got a sun shirt.
It wasn’t even a fancy one. Everybody on Reddit says to get the Rabbit hoodie, but it wasn’t in stock when I went looking. Instead, I ended up getting this UPF 50+ rashguard from Amazon for under $30, and a second shirt that I didn’t end up liking as much. And I started wearing them on my runs.
What are sun shirts for, and do they really work for runners?
Sun shirts have one main job: They protect you from UV rays (doing the same job as sunscreen). The good ones also wick sweat, which can end up keeping you cooler than if you were running without the shirt.
When it comes to UV protection, they definitely work. Dermatologists, including those at the American Academy of Dermatology Association, actually recommend wearing sun-protective clothing, in addition to seeking shade and using sunscreen. When you’re out on a run, shade may not be an option. And you’ll still need some sunscreen to cover your face and hands. But when it comes to your torso and arms, a sun shirt offers some pretty significant advantages over slathering on sunscreen:
- You can’t miss a spot, as you might when you’re trying to get sunscreen on the back of your arms and shoulders.
- You don’t need to reapply (as much) sunscreen on long runs, which can feel nearly impossible when you’re sweaty.
- You won’t have to deal with sunscreen sweating off or working its way across your skin (which is the main reason we need to reapply, anyway).
- If you use a spray sunscreen like I sometimes do, you won't have to deal with its sticky feel, and the fact that you're supposed to rub it in anyway.
- You’ll go through far less sunscreen each year—a pretty significant savings if you have sunburn-prone skin like me.
Aside from these objective points, the thing that really sold me was just that I hate the feeling of that suncreen-and-sweat slime dripping down my arms. It's gross, it gets on everything, and I do not want it.
What it feels like to run in a sun shirt: A lot less sweaty
I wore a sun shirt for the first time during a recent sweltering heat wave. I try to run in the evening or morning when it’s cooler, but no matter the time of day, the humidity was ridiculous and the wet bulb temperature was oppressively high.
I put on the shirt for an evening run first, sunscreened only the parts of me that weren’t covered (face, hands, lower legs), and ventured out. On balance, I don’t think I was hotter or cooler than I would have been without the shirt, but the slime situation was much improved. The shirt also absorbed and (sort of) wicked away my sweat. On the one hand, that means I’m running in a damp shirt. On the other: no dripping.
Intrigued, I wore a shirt again for a sunnier morning run, and had a similar experience. In a real show of how much I trusted these things, I even wore a sun shirt for the time I planned poorly and ended up having to do a midday run in 93-degree weather (don’t worry, I carried ice water and stayed safe); it worked well then too. On one of these runs, I noticed a light breeze, so I peeled off the shirt as I finished the run. The breeze on my skin felt nice and cooling, but it was more like a nice treat than regret that I'd been wearing the shirt in the first place. Safe to say I’m now a convert.
I did have one further “aha” moment. On one of my runs, I noticed that the shirt was long enough that it bunched up a bit around my hips. That extra fabric wasn’t doing me any favors, so I got out a pair of scissors and cropped the shirt just below my waistline. Now I get a bit of a breeze on my torso, while still keeping my skin out of the sun.
What to look for when buying a sun shirt
Any clothing marketed to runners tends to be expensive, although to be fair, it’s often lighter weight or better quality than bargain-basement stuff. Still, you don’t have to just search for “running sun shirt.” Also consider looking for “long sleeved wicking shirt,” “UPF shirt,” or even “rash guard” (a rash guard being a long sleeved shirt worn for surfing).
The ideal running sun shirt will have most or all of these features:
- A UPF rating (like SPF, but for clothing) - the higher the number, the better.
- Wicking or “cooling” fabric.
- A high neck or even a hood, to protect your neck and/or head.
- Thumb holes, which means longer sleeves, the better to protect your hands.
- Lightweight fabric—beware the rashguards that are designed with thicker swimsuit-type fabric.
- A moderately loose fit (although this is up to preference). If you normally buy from the women's section, consider the "men's" styles too—you might prefer the way they fit.
Sun protection experts tend to recommend colors that are dark (black, blue) or bright (red, yellow) rather than white or pastel. That’s because darker colors absorb more ultraviolet rays. Personally, I haven’t been able to convince myself to get a dark color when the shirts are available in white. Maybe black is more sun protective, but I’m worried it will be hotter. (This may be a “me” problem, so if you’re looking for good advice, listen to the dermatologists.)
With that in mind, here are some sun shirts, in a variety of styles and price ranges, that fit the bill. If you aren’t totally sold yet, start with a cheaper one and see how you like it. You might just join me in the less-slimy runners club.

The sun shirt I purchased offers UPF 50+ protection, which dermatologists recommend for protecting the skin from UV rays during outdoor activities. Unlike applying sunscreen, I no longer need to worry about missing spots on my back and shoulders while wearing the sun shirt.
After using the sun shirt on several runs, I notice a significant improvement in avoiding the gross, drippy slime of sunscreen mixing with sweat on my skin. In addition, I found that the fabric of the sun shirt wicks sweat away, reducing overall wetness during my runs.
