Sun Fact
At higher altitudes, a thinner atmosphere filters less UV radiation. With every 1000 meters increase in altitude, UV levels increase by 10% to 12%. To protect yourself, recommendations are to increase coverage of heads, hands and eyes in addition to arms and legs as you increase altitude.

Good choice for 8 year oldThese fit my slender 8 year old well. I love that they tie to adjust the waist inside. The stitching is quality and I can tell they’ll last a long time.

Great swim trunksThese are such cool swim trunks. My son really likes them. They are true to size too. They also are a thicker material and seem to protect against the sun.

Coolibar - Island Swim TrunksBought these adorable shorts for a baby but, unfortunately for the baby's parents, they were too big. I will order again in several months. Very nice quality!
