Shop kids swimwear from MOMASONG, including girls swimwear, boys swimwear, one-piece swimsuits, two-piece swim sets, rash guards and practical swim accessories. Use this guide to choose the right size and understand fabric, UPF, retail ordering, origin and shipping information.

Fabric and comfort
Swimwear fabric varies by style. Our main fabric options are polyester or nylon blended with spandex for stretch, comfort and easy movement. Check each product page for the most accurate composition, lining and care details. Many styles are designed with quick-dry performance for pool days, beach trips and water activities.

UPF protection
UPF 50+ protection is available only on styles specifically labeled UPF 50+ on their product page. Do not assume that every swimsuit, swim set or rash guard has the same UPF rating.

Size and fit
Use the size chart and product-specific measurements shown on each product page before ordering. Fit can vary by style, coverage and fabric stretch. If you are between sizes, compare the garment measurements with the child’s measurements.

Retail ordering and OEM information
Retail orders have no minimum order quantity. MOQ, sampling and lead time may vary for custom OEM/ODM projects and should be confirmed before production. In-stock retail orders are processed according to the shipping policy; custom production timing depends on style, quantity and customization requirements.
