10 Best UV-Rated Swimming Clothes and Gear for Kids

A long day at the lake or pool can be cut short instantly by a painful sunburn, especially when dealing with the sensitive skin of young swimmers. Relying solely on sunscreen means constant reapplications, missed spots, and chemical runoff in the water. Equipping kids with high-quality, UV-rated clothing ensures continuous physical defense against harsh rays so the focus stays on the water.

Understanding UPF Ratings for Children’s Water Gear

When selecting gear for the water, look for the Ultraviolet Protection Factor (UPF) rating, which measures how much UV radiation penetrates a fabric. Unlike SPF, which applies to liquid sunscreen, UPF rates both UVA and UVB protection built directly into the textile. A UPF 50+ rating is the gold standard, blocking 98% of harmful solar rays from reaching the skin.

It is vital to realize that not all fabrics protect equally, especially when wet. Standard cotton t-shirts offer surprisingly little protection once soaked, often dropping to a measly UPF 3 rating. True water recreation apparel utilizes tightly woven synthetic fibers like polyester and nylon blended with spandex to maintain protective integrity even when fully submerged.

Over time, chlorine, saltwater, and physical stretching can degrade this protective barrier. Investing in gear specifically engineered for marine environments ensures the physical weave does not loosen under tension. Always prioritize garments that rely on tight weaves rather than chemical treatments, as woven protection will not wash out over time.

Kids Rash Guard – Kanu Surf Keri UPF 50+ Rash Guard

A solid rash guard serves as the foundation of any water safety clothing setup, shielding the torso, shoulders, and upper arms. It minimizes the need for sunscreen reapplication on the high-exposure areas of the upper body while preventing board chafing during paddle boarding or body surfing.

The Kanu Surf Keri UPF 50+ Rash Guard is a standout choice because of its high-quality polyester and spandex blend. This shirt features flatlock seams that lie flat against the skin, preventing the painful rubbing that often happens after hours in saltwater. The fabric stretches easily, allowing kids to climb back onto swim platforms or paddle boards without restriction.

• Material: 80% Polyester, 20% Spandex
• UV Rating: UPF 50+
• Sizes: 2T to 16 (Toddler to Big Girls)
• Key Feature: Breathable, moisture-wicking quick-dry fabric

When purchasing, keep in mind that rash guards are designed to fit snugly to prevent drag in the water. If the child prefers a looser, t-shirt-style fit for beachside play, sizing up one or two sizes is highly recommended. This piece is perfect for active swimmers and paddleboarders, though it may be overkill for a quick, casual dip in a shaded pool.

Girls Swimsuit – Carter’s Simple Joys UPF 50+ One-Piece

A reliable girls’ swimsuit must balance comfort, coverage, and durability against pool chemicals and sun exposure. Traditional fashion suits often prioritize style over coverage, leaving shoulders and necklines exposed to direct midday sun. A proper UV-rated swimsuit reduces sun exposure while staying secure during active water play.

The Carter’s Simple Joys UPF 50+ One-Piece offers excellent coverage with a design built for movement. Made with quick-drying fabrics, it resists the heavy sagging that occurs when lower-quality suits get waterlogged. The sturdy straps stay put without digging into the shoulders, ensuring kids can dive, splash, and climb without constant adjustments.

• Material: Polyester/elastane blend
• UV Rating: UPF 50+
• Sizes: 12 Months to 5T
• Key Feature: Fully lined interior with quick-dry technology

Note that this suit is designed with a snug, athletic fit to ensure it does not sag under the weight of water. The lining provides extra durability, but it can take slightly longer to dry than unlined alternatives. This swimsuit is ideal for toddlers and young girls spending long afternoons at the pool or beach, though older kids may require more advanced athletic options.

Boys Swim Trunks – Kanu Surf Barracuda UPF 50+ Swim Trunks

Swim trunks are a staple for any boy’s water wardrobe, but standard pairs often lack proper UV protection and can cause severe chafing. High-quality trunks must protect the thighs from the sun while offering a comfortable interior that does not trap sand and moisture.

The Kanu Surf Barracuda UPF 50+ Swim Trunks are constructed from heavy-duty, high-performance polyester that holds up to rough pool edges and sandy beaches. Featuring triple-needle stitching at the seams, these trunks are built to withstand active play without tearing. The comfortable mesh lining prevents chafing, while the elastic waistband with a functional drawstring ensures a secure fit during high-dive jumps.

• Material: 100% Polyester cargo fabric
• UV Rating: UPF 50+
• Sizes: 2T to 20 (Toddler to Big Boys)
• Key Feature: Side cargo pockets with drainage grommets

Because the fabric is 100% polyester, these trunks have minimal stretch compared to spandex blends. Ensure you consult the sizing chart carefully, as a loose fit is necessary for comfortable leg movement. This gear is perfect for active boys who love dock jumping and beach running, but less ideal for competitive swim training where streamlined gear is preferred.

Kids Sun Hat – Sunday Afternoons Kids Play Hat

A high-quality sun hat is the single most important accessory for protecting a child’s face, eyes, and neck from overhead solar glare. Water surfaces reflect up to 50% of UV rays, making overhead protection from a wide brim absolutely critical for long days on the boat or beach.

The Sunday Afternoons Kids Play Hat is the industry standard for kids’ water safety. It features a wide, stiffened front brim to shade the eyes and a soft downward-sloping neck cape that protects the vulnerable neck area. The hat is made from water-repellent, stain-resistant nylon and features strategic mesh ventilation panels to keep young heads cool on humid days.

• Material: Nylon/polyester blend with water-repellent finish
• UV Rating: UPF 50+ (main body)
• Sizes: Small (6-24 months) to Large (5-12 years)
• Key Feature: Breakaway chin strap and adjustable sizing band

The breakaway chin strap is a crucial safety feature that prevents choking hazards if the hat catches on dock cleats or pool ladders. However, the wide brim can catch the wind on fast-moving boats, so securing the toggle tight is necessary. This hat is a must-have for beachgoers, kayakers, and pool loungers, but is not designed for underwater swimming.

Youth Swim Pants – Coolibar UPF 50+ Kids Water Leggings

While shirts and hats protect the upper body, the legs often remain completely exposed to reflecting UV rays during paddle boarding or shallow-water wading. Traditional sunscreen on legs washes off rapidly during kicking, making swim leggings a highly efficient alternative.

The Coolibar UPF 50+ Kids Water Leggings utilize premium swim fabric that is highly chlorine and saltwater resistant. These leggings fit like a second skin, reducing drag in the water while providing complete leg coverage down to the ankles. The flatlock seam construction prevents inner-thigh chafing, which is a common complaint when kids walk in wet clothes.

• Material: Aqua SUNTECT® polyester/spandex blend
• UV Rating: UPF 50+
• Sizes: XXS (4) to XL (14/16)
• Key Feature: Four-way stretch and chlorine-resistant chemistry

These leggings are designed to fit tightly, so pulling them on when wet can be a challenge. It is best to put them on dry before heading down to the water. This gear is perfect for paddleboarding, tide-pooling, and long snorkeling sessions, but is less necessary for short, shaded pool visits.

Infant Sunsuit – i-Play by Green Sprouts Snap Sunsuit

Infants have incredibly sensitive skin that cannot tolerate harsh chemicals or heavy sunscreens, making physical clothing barriers absolutely essential. A full-coverage sunsuit keeps babies safe from UV rays while ensuring they stay comfortable in and out of the water.

The i-Play by Green Sprouts Snap Sunsuit offers full-torso and upper-leg coverage with a lightweight, breathable design. The standout feature is the snap crotch closure, which makes diaper changes on the beach or boat incredibly easy without needing to strip the entire suit off. The fabric dries quickly, preventing the baby from getting chilled when transitioning out of the water.

• Material: 100% Polyester
• UV Rating: UPF 50+
• Sizes: 6 Months to 3T
• Key Feature: Quick-snap diaper access and mock-neck collar

While this sunsuit is highly protective, it does not feature a built-in reusable swim diaper, so a separate swim diaper must be worn underneath. The material is delicate, so avoid rough concrete pool decks to prevent fabric pilling. This is an indispensable piece for families taking infants to the beach, lake, or splash pad.

Kids Water Shoes – CIOR UPF 50+ Quick Dry Aqua Socks

Sun protection does not stop at the ankles; the tops of feet are incredibly susceptible to severe sunburns when floating or wading. Additionally, hot sand, sharp shells, and slippery pool decks present physical hazards that require durable underfoot protection.

The CIOR UPF 50+ Quick Dry Aqua Socks combine the flexibility of a sock with the protective sole of a shoe. The upper material is made of a stretchy, UV-rated fabric that fits snugly to keep out sand and small pebbles. The anti-slip rubber sole provides excellent traction on wet docks, slippery boat decks, and slimy river stones.

• Material: Stretchy polyester upper with durable rubber sole
• UV Rating: UPF 50+ (upper fabric)
• Sizes: Toddler 4.5M to Big Kid 6M
• Key Feature: Multi-drainage holes in the sole

Because these shoes are designed to fit tightly like socks, sizing can run small, and wide feet may require sizing up. Airing them out completely after use is critical to prevent musty odors. They are perfect for rocky rivers, tide pools, and splash pads, but are not intended for long-distance hiking or rugged terrain.

Kids Swim Jumpsuit – SwimZip UPF 50+ Short Sleeve One-Piece

Wrestling a wet, wriggling child into or out of a tight rash guard is a challenge every water-loving parent knows too well. A swim jumpsuit solves this hassle by combining top and bottom coverage into a single, easy-access garment.

The SwimZip UPF 50+ Short Sleeve One-Piece features a full-length front zipper that makes changing incredibly simple, even when the fabric is soaking wet. A protective zipper flap prevents the zipper from rubbing against the neck or catching skin. The short-sleeve design offers solid shoulder coverage while keeping arms free for active swimming.

• Material: Nylon/spandex blend
• UV Rating: UPF 50+
• Sizes: 0-3 Months to 12-14 Years
• Key Feature: Full-length zipper with protective chin guard

Because this is a one-piece garment, torso length is critical for a comfortable fit; a torso that is too short will cause pulling at the shoulders and crotch. This suit is the ultimate choice for quick changes at public pools and beaches, though kids who prefer mixing and matching tops and bottoms may find a one-piece limiting.

Kids Swim Parka – Sporti UPF 50+ Youth Hooded Swim Parka

Protection from the sun and wind does not end when children exit the water. Shivering on the pool deck or boat deck can ruin a fun day, making a protective, warming layer an essential part of the gear bag.

The Sporti UPF 50+ Youth Hooded Swim Parka features a water-resistant outer nylon shell and a soft fleece lining that absorbs moisture while keeping kids warm. The built-in hood provides instant protection for wet heads against cold breezes and intense sun. The heavy-duty front zipper is easy for small hands to operate, even with cold fingers.

• Material: Nylon outer shell with polyester fleece lining
• UV Rating: UPF 50+ (outer shell)
• Sizes: Youth XXS to Youth L
• Key Feature: Polar fleece lining and deep zippered pockets

This parka is bulkier than standard towels or cover-ups, requiring significant space in your dry bag or boat compartment. It is an investment piece designed for competitive swim team members, cold-water boaters, and early-morning beach trips rather than casual, hot-weather pool visits.

Kids Sunglasses – Babiators Original Navigators UV Sunglasses

Water surfaces reflect up to 80% of UV radiation, increasing the risk of long-term eye damage for children whose eyes are still developing. Standard cheap sunglasses often shatter easily or fail to block harmful UVA and UVB wavelengths.

The Babiators Original Navigators UV Sunglasses feature high-performance, impact-resistant lenses that provide 100% UVA and UVB protection. The frames are made from a flexible, durable rubber that can be twisted, bent, or stepped on without breaking. They fit comfortably on small faces without pinching behind the ears.

• Material: Flexible rubber frames with shatterproof polycarbonate lenses
• UV Rating: 100% UVA/UVB protection
• Sizes: 0-2 Years, 3-5 Years, and 6+ Years
• Key Feature: Lost or broken replacement guarantee

While these glasses are virtually indestructible, they do not float on their own. Adding a floating neoprene eyewear retainer strap is highly recommended if using them on deep water or during paddle sports. These are perfect for active kids on boats, beaches, and docks, but may be easily misplaced by younger children without supervision.

How to Wash and Care for Children’s UPF Swimwear

Maintaining the protective integrity of UPF fabrics requires proper care after every water session. Chlorine, saltwater, and sand can get trapped in the tight weave of the fabric, gradually stretching out the fibers and degrading the UV protection. Always rinse swimwear in cool, clean water immediately after leaving the pool or ocean to flush out damaging chemicals and salt crystals.

Never toss UPF clothing into a hot washing machine or dryer. High heat breaks down the spandex and elastane fibers, leading to a saggy fit and significantly reduced sun protection. Instead, hand wash with a mild detergent, or use a gentle cycle with cold water, and lay the garments flat to air dry in the shade.

Avoid wringing out wet gear with excessive force, as this damages the protective weave. Instead, roll the wet garment in a dry towel and press gently to absorb excess moisture before hanging. Proper maintenance ensures that your children’s protective gear maintains its certified UPF rating season after season.

Conclusion

Investing in high-quality, UPF-rated gear keeps the focus on fun and safety rather than sunburn recovery. With the right protection from head to toe, young water enthusiasts can confidently explore beaches, lakes, and pools all summer long. Secure your gear, pack the boat, and get ready for worry-free days on the water.
