But before you go running out to buy one, take a beat—there’s a few key elements to keep in mind when it comes to rash guard design.
What to look for in a rash guard
First is fit: the overall style and silhouette of your rash guard will make a difference depending on the water activities you participate in. If you’re a surfer or avid boogie boarder, aim for something a little tighter to prevent chafing between the fabric, your board, and your stomach. For paddlers or recreational swimmers, a looser style might be more comfortable.
Second is SPF, or in the case of rash guards, UPF. UPF, or ultraviolet protection factor, is the standard unit of measure for how well fabric blocks out UVA and UVB rays. If you’re shopping for a rash guard, aim for a shirt that’s made with UPF 50 or above. According to the American Skin Cancer Foundation, these block 98 percent of the sun’s rays, and will keep you most protected from as you swim or surf.
Finally, consider your lifestyle: Will a crew neck rash guard suffice? Or, do you need something a little more protective with additional features, like a zipper or a hood? Is this an investment you’re going to wear from season-to-season? Or is it something you’re purchasing as a one-off for your next vacay?
The best rash guards for long-lasting protection against the sun and surf
Whether you’re an olympic-level surfer or the occasional weekend paddler, there’s a rash guard for you. Below are the 12 best rash guards for the lake, beach, and beyond. (Editor’s note: While we’ve included the best picks for women and men, this definitely doesn’t mean you shouldn’t buy what is best for you, and what you like, regardless of how you identify—we’re merely answering commonly searched terms in Google.)
