Perfect for summer adventures
Great Sun Protection and Comfort! I've been incredibly pleased with the Willit Boy's UPF 50+ Sun Protection Shirt. This rash guard has been a lifesaver during our family's lake trips. The bright yellow color is easy to spot in the water, providing added safety. The UPF 50+ rating offers excellent protection against harmful UV rays, ensuring my son's skin stays safe. The shirt fits perfectly and is incredibly comfortable to wear. It's lightweight and breathable, making it ideal for long days in the sun. The quick-dry material is a huge plus as it keeps him cool and dry. I highly recommend this rash guard to any parent looking for a reliable and comfortable sun protection option for their child.

Great swim shirt
Vivid swim shirt that protected my child from the sun all summer. Washes well and air dries quickly.

Size fits well, quick drying
The size chart was accurate and the XS fits great for my little one that wears 5T in clothing - it does fit snug, but should since it's a rash guard. The rash guard seems to be well made, the red color is bright (the fabric is very shiny), it's worked great with daily use at the swimming pool so far. I wash it on cold and line dry it - it dries very quick.

Good!
Bought size L for my 11 year old and he wore it on our trip to Turks and Caicos. It fit him well and prevented him from getting sunburn. Value for money as I’ve seen other shirts like this much more expensive with the same quality!

Great Summer Staple
We love rashguards for extra sun protection and to prevent chafing/rub from life jackets, and this has been our go to all summer! The color and fit are just as described, and we haven’t noticed any fading or staining, despite lots of time spent in the sun, sand, and chlorine. We’ve been able to match it easily with different trunks to really stretch the usage. My son is a 5/6 in both tops and bottoms and this fit well. I’m planning on buying a couple more in different colors and a size up for vacation and next summer!

Excellent Sun Protection and Perfect for Outdoor Activities
This shirt has been a great find for keeping my son protected during long days outside. Whether he's at the beach, fishing, or just running around the yard, the Willit UPF 50+ shirt gives me peace of mind knowing he's covered. The material is lightweight, breathable, and dries quickly, which is perfect for hot summer days and water activities. It’s also surprisingly soft and comfortable—he didn’t complain once about wearing long sleeves in the heat. Plus, it holds up really well in the wash with no fading or shrinking. I also love that it doesn't look too "swimwear-like"—it doubles nicely as a regular long sleeve for hiking or park days. I’d say the fit is true to size, with just enough room for movement. Highly recommend if you're looking for a high-quality rash guard or sun shirt that actually delivers on comfort and protection.
