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.

Size guide
Rated 5 out of 5 by from Good choice for 8 year old These 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.

Rated 5 out of 5 by from Coolibar - Island Swim Trunks Bought 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!
