Boys One Piece Swimsuit 4-12Y Long Sleeve Zipper Rash Guard UPF 50+ Sun Protection

Washing Instructions: Hand-wash cold (≤86 °F) with mild detergent; gently squeeze, do not wring. If machine-washing, turn the suit inside-out, place in a mesh laundry bag, and use a gentle cold cycle. Wash with like colors; launder separately the first time. Do not use bleach or fabric softener. Do not tumble-dry or iron. Press out excess water and lay flat in the shade to dry. Care Tips: Fabric contains polyester and spandex; avoid hot water and high-heat drying to help preserve stretch. Rinse promptly after swimming to remove chlorine, salt, sand and sunscreen. Avoid rough surfaces that can snag the fabric; let kids sit on a towel when possible. Do not store damp suits for long periods—allow to air-dry fully before putting away. Store dry in a ventilated drawer or bag, away from sharp objects.

• HIGHER-SPANDEX SOFT-FLEX POLYESTER: This all-over print boys one piece swimsuit uses 82% polyester and 18% spandex for a higher-stretch profile than many basic 85/15, 88/12, or 90/10 polyester-spandex swim builds. The soft-flex knit feels smoother and gentler without being heavy, with a lightweight quick-dry feel for long swim sessions, backyard splash play, camp games, family outdoor activities, and warm-weather movement.
• UPF 50+ SUN PROTECTION DRY & WET TESTED: Complete one-piece swimsuit samples were independently tested to AATCC TM183-2020e in dry and wet states. Tested fabric constructions used throughout this style are rated UPF 50+ and block 99%+ UVA/UVB rays where covered. Long sleeves and one-piece coverage help cover shoulders, arms, back, torso, and upper legs. Protection applies only where covered and may reduce with stretch, wear, laundering, chlorine, saltwater, or long sun exposure.
• HIGH-SATURATION KID-COOL GRAPHIC PRINT: This boys long sleeve rash guard swimsuit uses bold all-over artwork instead of a plain solid body, giving kids swimwear a bright, expressive look for pool days, beach trips, water parks, camp activities, backyard splash play, and vacation photos. Licensed digital graphics add color, motion, and conversation-starting personality, while contrast sleeves keep the style clean and sporty.
• EASY ZIP-FRONT WITH SMOOTH JERSEY LINING: No hard-to-reach back zipper. The front zipper helps kids get dressed faster and makes wet changes easier for parents. A covered zipper and chin guard help reduce rubbing near the neck. Flatlock seams and 4-way stretch support swimming, jumping, bending, and running. In the gusset, a smooth 92% polyester / 8% spandex jersey lining feels soft against skin and rinses clean to help reduce trapped sand.
• CHLORINE-TESTED COLOR + EASY CARE: Printed fabric is tested for colorfastness to chlorinated pool water under AATCC TM162, with a Color Change rating of 4, helping artwork stay vivid through regular pool use with proper care. The tested print part also achieved a 4.5 pilling-resistance rating under ASTM D3512 after a 30-minute random tumbler test. Sizes 4-12Y. Size up if between sizes. Rinse promptly, hand wash cold, lay flat to dry.
