Picks by Category
Men's rash guards
The reliable, affordable benchmark. UPF 50+, flatlock seams, good stretch. Used by surf schools worldwide as a rental rash guard for good reason.
Slightly better construction than the O'Neill Basic. 4-way stretch, UPF 50+. Good fit for broad-shouldered surfers.
Premium feel, excellent stretch, lightweight. Good choice for surfers who want a step up from basic. Dries very quickly.
More expensive but uses recycled materials and has excellent durability. For surfers who care about brand ethics and long-term wear.
Women's rash guards
One of the best-fitting women's rash guards available. UPF 50+, flatseam construction, good shoulder mobility. Available in multiple prints.
Same quality as the men's version, cut for a more fitted women's silhouette. The affordable benchmark.
Good UPF protection, comfortable fit, and a wide range of colour options. Popular for tropical surf travel.
Crossover from swimwear — better aesthetics than surf-brand rash guards if appearance matters. Solid UPF 50+ protection.
Kids' rash guards
The kids' version of the benchmark. Durable, UPF 50+, easy to pull on and off. Available in sizes 2T through 14.
Good fit for girls, bright colours kids like, UPF 50+. Holds up well to heavy use and repeated washing.
Amazon and budget brands make functional kids' rash guards at this price. Check that the UPF 50+ claim is certified, not just printed. Look for OEKO-TEX or UPF Standard 801 certification.
What to Look For
The standard for surf rash guards. Blocks 98% of UV. Lower UPF ratings (20, 30) provide meaningful protection but UPF 50+ is the benchmark worth looking for.
Flatlock seams lie flat against the skin — no raised edges to chafe under a wetsuit or against a board. Cheaper rash guards use raised seams that cause irritation during long sessions.
These blends dry quickly, stretch well, and maintain UPF rating when wet. Cotton rash guards lose UPF when wet and take too long to dry.
Necessary for the shoulder and arm range of motion required in paddling. A rash guard that restricts your paddle stroke will tire you out faster.
Keeps the sleeves pulled down and prevents them riding up under a wetsuit or when paddling. A small feature that makes a noticeable difference in comfort.
A loose rash guard billows underwater and creates drag. Too tight restricts the arm movement needed for paddling. Snug with full range of motion is the goal.
What to Wear in Different Conditions
Warm water (75°F+) without wetsuit
Long sleeve UPF 50+ rash guard + boardshorts or bikini. Reduces sunscreen needed to face, neck, and hands only.
Cool water (65–75°F) without wetsuit
Long sleeve rash guard as base layer. May want a light 2mm shorty over it depending on wind chill and session length.
Under a wetsuit (any temp)
Thin long sleeve rash guard under the wetsuit. Reduces chafing significantly, especially on the neck and wrists. Makes wetsuit easier to put on.
Kids in any conditions
Always long sleeve UPF 50+ regardless of temperature. Children burn faster than adults and often do not notice until the session is over.

Frequently Asked Questions
What does a rash guard protect against?
UV radiation (sun protection), board rash (friction from lying on your surfboard), and wetsuit chafing when worn underneath neoprene.
What is UPF rating in a rash guard?
UPF 50 blocks 98% of UV rays — equivalent to SPF 50 sunscreen but more reliable since it does not wash off. Look for UPF 50+ for surfing.
Should I wear a rash guard under my wetsuit?
Optional but recommended. It reduces friction at the neck, wrists, and ankles — the main areas where neoprene rubs. It also makes putting on and taking off a wetsuit easier.
Long sleeve or short sleeve rash guard for surfing?
Long sleeve for sun protection and under-wetsuit use. Short sleeve for very warm conditions where full arm coverage is too hot.
