For a long day at the beach, you can shield your upper body from the sun’s harmful rays — and look darn good in the process — by wearing a top that provides great UV protection. That’s the job of beach or swim tops known as “skins” or “rash guards,” which are specifically designed for use in or on the water, pair perfectly with swimsuits and don’t impede movement or get in the way.

This summer a large number of outdoor clothing companies offered skins and rash guards in a variety of designs. With the arrival of August seasonal clearance sales, you might want to check out your favorite brands to grab a great-looking skin at a good price. Meanwhile, here are two designs to inspire you:

The material in O’Neill’s Basic Skins line for men is recommended by the Skin Cancer Foundation. The Basic short sleeve crew offers 50+ UV Protection, with minimal seams to prevent rash. Made from polyester and spandex (which allows four-way stretch), it’s quick-drying, size small to XXL, and comes in six colors. $31.95. A long-sleeved version is $33.95. www.oneill.com

Roxy’s Softly Love long-sleeved zippered rash guard for women offers UPF 50 sun protection. It’s made from 87% nylon and 13% elastane, resulting in a soft fabric with stretch resistance, and has a crew neckline and front half-zip opening. Sizes XS to XL. Colors: Withered Rose Lily House and Trellis Bird Flower Swim. $60.

You can also buy a matching bikini bottom ($40) and top ($50). www.roxy.com
