Rash Guards

Shop kids rash guards at MOMASONG for beach days, pool sessions, swim lessons and outdoor water play. Rash guards are a practical choice for families who want comfortable coverage and easy layering with swimwear. This collection includes short-sleeve and long-sleeve rash guard styles, coordinated rash guard swim sets and one-piece rash guard swimsuits for girls and boys.

Kids rash guards are designed to move with children while they swim, play and explore. Depending on the style, features may include lightweight stretch fabric, quick-drying construction, soft lining, comfortable cuffs, secure hems and matching swim bottoms. Long-sleeve designs can offer more coverage for outdoor activities, while short-sleeve styles are easy to layer over a swimsuit. Check each product page for the exact fabric composition, lining, fit and sun-protection information. UPF 50+ applies only to styles specifically labeled with that rating, and sun-protective clothing should be used together with shade and other sun-safety practices.

For the best fit, compare your child’s height, chest, waist and hip measurements with the size chart on the individual product page. A rash guard should feel comfortable across the shoulders and arms without restricting movement. Consider whether you prefer a close fit for layering or a more relaxed fit for everyday play. This is a ready-to-wear retail collection for children and families; it does not include baby or infant swimwear.

Rinse rash guards with clean water after swimming and air dry them away from direct heat. Avoid bleach, fabric softener and rough surfaces that may snag the fabric. Follow the product care instructions to help maintain color, stretch and shape through repeated wear.
