Most kids' UV shirts use synthetic blends and some cotton. Typical examples shown in product listings include 90% polyester/10% spandex, 80% nylon/20% spandex, and cotton.
Some kids' UV shirts explicitly list a numeric UPF rating—examples include UPF 50+—while others only describe offering protection against harmful UV rays without a specific value. If a defined level of sun protection matters to you, look for products that state a UPF rating.
You can find both short-sleeve athletic tees and long-sleeve rashguards among kids' UV shirts.
Available sizing includes toddler sizes (for example 4T–5T), youth sizing (such as 10Y), and some listings specify age ranges (one notes ages 2–9). Check each product's size chart for exact measurements and fit guidance.
They commonly advertise moisture-wicking and quick-dry performance, breathable fabrics to help keep kids cool and dry, and built-in UV protection.
Some products list certifications in their details—for example, one garment notes STANDARD 100 by OEKO‑TEX. If certifications matter to you, look for specific certification names in the product description.
Prints are described using technical inks or poly-printing processes intended to produce smooth, durable, vibrant graphics; other items are described simply as bold graphic tees without technical-print details.
Some listings state the garment is made or cut-and-sewn in the USA—examples include items made in the USA from imported fabric and pieces cut-and-sewn in Los Angeles.
