SwimZip Boys Long-Sleeve UPF 50+ Swimsuit for Baby to Little Boys UVB

Our review of the SwimZip Boys' Long-Sleeve UPF 50+ Swimsuit finds it best suited for parents who want straightforward, full-coverage sun protection for infants, toddlers and little boys up to about age 6. The standout reason to buy is the certified sun protection: this sunsuit is Skin Cancer Foundation certified and made from UPF 50+ fabric, so it blocks the vast majority of UVA and UVB rays while still being quick-drying and comfortable for water play.

Key Features

• Certified sun protection: The Skin Cancer Foundation certification and UPF 50+ material offer reliable, tested blocking of harmful UVA and UVB rays to reduce the need for chemical sunscreens on covered skin.
• Full body coverage: Full-length sleeves and full leg coverage keep wrists and ankles covered to prevent burns and reduce life-jacket chafing during active swim time.
• Full front zipper: The full-length front zipper makes dressing and especially diaper changes quick and easy, even when the suit is wet.
• Comfortable construction: Raglan cut sleeves and flatlock seams give good freedom of movement and reduce irritation for babies and toddlers who are constantly on the go.
• Durable, easy care fabric: Saltwater- and chlorine-resistant, quick-drying fabric with 4-way stretch that is machine washable and line dry friendly for busy families.
• Family matching options: Available in coordinated pieces and sets so parents can match kids or choose separates for more variety.

Who It's For

The SwimZip sunsuit is aimed at families with infants, toddlers and little boys who spend time at the beach, pool or lake and need dependable sun protection without constant reapplication of lotion. It suits caregivers who value easy diaper changes and clothing that holds up to chlorine and saltwater.

Families who prefer looser layering for hot climates or who need sun coverage only for arms may prefer separate rash guards and trunks; likewise, parents seeking swimwear with built-in flotation or thermal insulation should look elsewhere.
