First off, let me say this shark-themed swim set is ADORABLE. The bright colors and fun design make it a hit with kids (and parents who want to spot them easily in the water!).

The UPF 50+ protection is legit - my son wore this all day at the beach and didn't get even a hint of pink. The rashguard's fabric (86% recycled poly!) feels surprisingly soft, not scratchy like some sun shirts. It dried crazy fast after water play.

About sizing: Runs pretty true to size but with a slight quirk. My tall 5-year-old fits perfectly in the 4T waist (thanks to the adjustable drawstring), though the trunks are slightly long. Pro tip: If your kid is between sizes, size down for better waist fit - you can always roll the trunks a bit.

The quality surprised me - after multiple pool/beach trips and washes, the colors haven't faded one bit. No loose threads or stretched-out elastic either.

Only minor complaint? The shirt runs slightly snug when wet (like most rashguards), but my son never complained about comfort even during hours of splashing around.

Final verdict: At full price it's decent, but if you catch it on sale? Absolute steal for how well it performs. This set has become our go-to for any water activity!
