Men's Scuba Diving Rash Guards – UPF 50+ | Diver Bubbles

Men's scuba diving rash guards built for real dives. Every rash guard is long-sleeve for UPF 50+ sun protection, cut from quick-dry four-way stretch fabric, and shaped slim so it layers clean under a wetsuit. Each one wears an original all-over-print ocean design, sublimated edge to edge so it never peels or fades. Whether you're spearfishing a reef, hanging in the blue for hammerheads, or covering up on the surface between tanks, these are dive rash guards made to be worn in the water — not just on the beach. Designed and tested by divers in Greece, printed and sewn to order, shipped worldwide.

How divers actually wear a rash guard

Most divers own one for two jobs: sun cover on the surface and a slip layer under neoprene. The long sleeve is the point — shoulders and forearms take the worst of the reflected light off the water, and reapplying sunscreen between tanks is a losing battle. Under a wetsuit, the smooth face lets 5mm neoprene slide over your arms instead of grabbing wet skin. The close fit means there is nothing loose to bunch where a BCD strap and tank band pass.

Frequently asked questions

Can you wear a rash guard under a wetsuit?

Yes, and most divers prefer it. A thin rash guard lets neoprene slide on and off far more easily, stops the suit chafing your neck and armpits, and adds a fraction of warmth. Choose a slim, seamless-feeling fit — anything bulky or bunched will fold and rub under the suit.

Does a rash guard protect you from the sun in the water?

Yes. These men's rash guards are rated UPF 50+, blocking at least 98% of UV rays, and unlike sunscreen the protection does not wash off or need reapplying mid-dive-day. Coverage only extends where the fabric sits, so keep sunscreen for your face, ears, hands and the backs of your knees.

What size rash guard should I get for diving?

Take your normal t-shirt size for a close, second-skin fit. Rash guards are meant to sit snug — a loose one balloons in the water and bunches under a wetsuit. If you are between sizes and wearing it as topside sun cover rather than a base layer, go up one.

How do I stop my rash guard smelling after a dive trip?

Rinse it in fresh water the moment you get off the boat, before the salt dries in. Salt crystals hold bacteria and stiffen the fibres. Wash cold with mild detergent, no fabric softener, and hang it in the shade — direct sun on wet technical fabric shortens its life.
