boys 4th of july swim trunks

Most trunks use polyester-based fabrics and stretch blends, for example "90% Polyester, 10% Spandex" or "93% Polyester, 7% Spandex." Some options are listed as "100% Recycled Polyester."

Most listings state UPF 50 or UPF 50+ sun protection; several product notes describe UPF 50/50+ as the highest available rating shown in these trunks.

Common styles include pull-on elastic waistbands (sometimes full elastic) and front drawstrings or adjustable drawcords/ties; a few listings note flexible or integrated drawstrings alongside elastic waistbands.

Product descriptions commonly highlight quick-dry or performance features, using phrases like "quick dry," "water-repellent fabric," or "performance hybrid construction," and reference polyester-spandex blends for fast drying and shape retention.

Care instructions vary by product but typically list machine wash; some items specify tumble dry while others recommend line dry or laying flat to dry—check each product's label for the manufacturer's recommendation.

The selection includes themed prints such as "Red/White/Blue Fireworks," "Blue Patriotic Gingham," and an "Americana flag" print, among other red, white, and blue patriotic patterns.
