What to consider before buying

When choosing a baby sunsuit, prioritize UPF 50+ rating, full zip or snap closures for easy diaper changes, and a snug but comfortable fit. Look for chlorine-resistant fabric if using frequently in pools, and consider long sleeves for maximum sun protection. Many sunsuits run small, so size up if between sizes.
