Sun Protection That Looks Cool

  • Stay protected from the sun with fabric rated UPF 50+ for ultimate sun protection.
  • Added protection for her neck thanks to a crew/mock collar that extends the sun protection to her neck.
  • Dry off fast with moisture wicking, quick drying fabric.
  • Move with ease thanks to the four-way stretch fabric that allows for unrestricted movement.
  • Added comfort with chafe-resistant flat-lock seams for everyday use.
  • Cool water style available in two vivid water-print colors.
  • Relaxed comfort designed as a “comfort-fit”, in-between a “compression-fit” and “loose-fit.”

Protect the skin of the tween (pre-teen/teen) girl in your life, and she will look great too with this extremely comfortable, relaxed-fit rash guard swim shirt. Available in two vibrant colors, the fun 3-D water pattern looks cool, and she will like the feel of the quick-dry, soft four-way stretch fabric. In our research, a common complaint about rash guards is that they're just too tight. Not everyone wants the extra-tight fit of a compression garment. Each of our shirts is sized similarly to a form-fitting T-shirt, so the fit is somewhat snug but not compression tight. If you prefer the compression fit of a traditional surfer's rashie, select one size smaller. If you're looking for a looser fit than you'd normally find with a form-fitting T-shirt, we'd suggest you order a size or two larger.

Care Instructions:

Cold water machine washable, hang dry (or light dryer setting).
