We've done the hard work for you!

Platinum Sun rash guards for men and women are crafted with the needs of watersports athletes in mind.

With no ride-up, you can focus on your performance with complete comfort and confidence while keeping your skin shielded from harmful UV rays.

15 products

Seventeen long sleeve rash guards and swim shirts, all UPF 50+, all cut for a woman's shape rather than shrunk down from a men's pattern. Wear them surfing, kitesurfing, paddling, snorkeling, or over a bikini on a boat when you have simply had enough sun.

What UPF 50+ actually does

It blocks around 98% of UVA and UVB rays, and unlike sunscreen it does not wash off, sweat off, or need reapplying halfway through the day. No white face, no greasy hands on your bar or paddle. Sunscreen goes on whatever the fabric leaves bare, and that is the whole routine.

Choosing your fabric weight

  • Light. Thin and breathable, cools you when wet in hot weather. Best for summer and warm water.
  • Core. Medium weight, fully opaque, warmer. Good for cooler days and Florida winter.
  • Warm. Fleece-lined without the bulk. For cold water, early mornings, or as a base layer under a wetsuit.

Details that stop the fussing

Thumbholes keep sleeves down when you are paddling. A rubbery silicone strip at the hem stops the shirt riding up over your ribs. Shoulder zippers on some styles make getting in and out easier when you are wet. Flat-lock seams sit flush so nothing rubs on a long session.

Do rash guards have a built-in bra?

No, and almost none on the market do. Wear yours over a swim top or sports bra, the same way you would a fitted t-shirt.

Wear it wet, not as a casual top

A rash guard is built to be worn wet. The fabric cools you as the water evaporates off it, which is exactly what you want in the sun, but dry on a hot day it can feel warm. The Active series is the exception, because it uses the same soft fabric as our leggings and stays comfortable dry.

How to pair it

One bright piece, one solid. A printed rash guard with solid leggings, or a solid top with printed leggings. Two big prints together compete with each other, and the whole thing stops looking put together.

Prints, because black is a choice not a rule

Rainbow, Stripes, Art and Active, plus the Victoria hooded jacket with pockets. Each series comes from a different designer, so the cut and fabric vary slightly. The product page tells you which is which.

Rash Guard for Women - Comparison Chart

Platinum Sun’s rash guards are similar in form and function, sharing features such as UPF 50+ protection and full sublimation. It's important to note that all rash guards are designed to fit tightly, with the tightness increasing with the thickness of the fabric when worn. However, each collection of rash guards represents the vision of a different designer, resulting in some variations. These collections may differ in the cut of the neck, fabric composition, and other small features, which are clearly displayed on each product’s page.
