Sun Protective Gear
The best kids rash guards and sun shirts
The single highest-return purchase in a family sun routine: it covers the torso all day and never needs reapplying.
Disclosure: Spf & Shore earns commission from qualifying purchases made through links on this page, at no extra cost to you. It does not change which products we recommend. Read the full disclosure.
Our pick is the [Coolibar Kids Hooded Rash Guard](#coolibarKidsRash) — UPF 50+ rated wet or dry, with a hood that covers the back of the neck, which is one of the two places a child most reliably burns.
If you change one thing about how your family handles sun, make it this. A UPF 50+ swim shirt covers the entire torso for the whole day, cannot be toweled off, never needs an alarm, and does not sting. Reapplication then shrinks to face, hands, feet and lower legs — a two-minute job instead of a five-minute wrestling match, four times a day.

Why this beats any sunscreen upgrade
Sunscreen fails for behavioral reasons, not chemical ones. People apply too little, miss areas, forget to reapply, and towel it off. Every one of those failure modes is specific to a topical product, and none of them applies to a shirt.
For a child the gap is wider still, because reapplication depends on an adult catching a moving target at the right interval. A garment does not depend on anything. The American Academy of Pediatrics puts clothing and shade ahead of sunscreen in its guidance for exactly this reason.

How to choose one
- UPF 50+, rated wet or dry. The wet rating is the one that matters for swimwear, and good brands state it explicitly. Does UPF clothing work wet.
- Long sleeves. Short-sleeve rash guards exist and leave the forearms — a high-exposure area — uncovered.
- A hood, if you can get one. It covers the back of the neck, which is where children burn when they are looking down at sand or water.
- A zip at the neck for younger children, because getting a wet rash guard off a tired four-year-old without one is genuinely difficult.
- Flat seams, which matter on skin that will be in sand and salt all day.
Sizing, and the mistake most parents make
Buy the correct size, not a size up. Rash guards are cut close so they do not drag in water, and an oversized one billows, chafes under the arms and rides up to expose the lower back — which is then the part that burns.
Close-fitting is not the same as tight. A stretched fabric has larger gaps between fibers and transmits more UV, so a rash guard straining across the chest protects less than one that fits. The test: you should be able to fit a flat hand between the fabric and the chest, and the hem should stay put when the child raises both arms. Rash guard fit guide.
What still needs sunscreen
- Face, ears and nose. A stick is the fastest format and does not sting. Best sunscreen sticks for kids.
- Hands and the tops of feet, both consistently missed and both painful when burned.
- Lower legs, unless you are also buying swim leggings, which exist and are worth considering for a full beach day.
- The back of the neck, if the shirt has no hood.
Care that preserves the rating
Rinse in fresh water after salt or chlorine, wash cool, and line dry. Chlorine and hot tumble drying both degrade elastane over time, and a garment that has gone thin and slack has lost protection regardless of what the label said when new. Fabric-based UPF does not wash out; the fabric simply wears out, like any other garment.

Frequently asked questions
Do kids rash guards protect from the sun?
A UPF 50+ rash guard blocks at least 98% of UV across the area it covers, for the whole day, with no reapplication. Check the garment states UPF 50+ rated wet or dry — an ordinary cotton T-shirt is around UPF 5 to 7 and drops further when wet.
Should a kids rash guard be tight or loose?
Close-fitting but not tight. Oversized ones billow, chafe and ride up to expose the lower back. Stretched-tight ones open the gaps between fibers and transmit more UV. You should be able to fit a flat hand between the fabric and the chest.
Do children still need sunscreen with a rash guard?
Yes, on everything the shirt does not cover — face, ears, hands, the tops of the feet and the lower legs. The rash guard removes the torso from the problem, which is most of the area but not all of it.
Does the UPF rating wash out of a kids swim shirt?
Not in a well-made garment, where protection comes from the fiber and weave. What does happen is wear: chlorine and hot tumble drying degrade elastane, and a shirt that has gone thin and slack protects less. Rinse in fresh water, wash cool and line dry.
