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.

Rated 5 out of 5 by from Great choice ! I requested these for my husband. He’s about 5’11 and 190 lbs. I got him size Large. They fit great. They do rid up a little bit in the crouch but my husband doesn’t mind he thinks it’s great. He really wants the yellow ones next! I can’t wait for our next trip to put our Coolibar stuff to the test.

Rated 5 out of 5 by from Great Looking and Well Made I was very pleased with fit and quality. They are attractive. I cannot vouch for reliability or "see through" issues since they are so far untested.

Rated 5 out of 5 by from Perfect swim trunks - fit and fabric My husband loved the swim trunks - the length protected his legs and the fabric was light enough to be cool during our 98 degree visit to the beach. Paired with the Ultimate rash guard for perfect coverage.

Rated 5 out of 5 by from Top Quality I bought this bathing suit for my 14 year old grandson mainly because I thought the black and white color pattern would not attract sharks as he swims in the ocean in Florida. So far no shark problem plus the swimsuit fits perfectly and he likes it very much.

Rated 5 out of 5 by from Comfy & Cool Bought these for my son. The fabric is great -- nice and soft and they are comfy and cool. Nice colors -- just as shown. Fit is great. He has another pair of these in a different print from 2 years ago that fit my younger son now. These last a long time.

Rated 5 out of 5 by from Comfortable and high quality! This was my first time buying from this company and I'm impressed.The quality of the material was really nice (stretched and moved really well). I bought this for my boyfriend who is 6'6" and what I really liked was the longer inseam so they don't look too short on him. Overall great product and I will probably be purchasing more from this company in the future.

Rated 5 out of 5 by from Coolibar quality Live by the beach and wear swimsuits every day in summer. Have used coo libra products exclusively for many years and they ever disappoint. Swimsuit good fit and quality construction.

Rated 4 out of 5 by from Great suits! My husband liked the bathing suits and said they were good looking, comfortable suits, but the one tiny pocket is not big enough for items like a credit card and keys if you are at the beach.

Rated 5 out of 5 by from The Best Swim Trunks-Ever!! Fabric&Fit Fantastic!! Finally trunks that stay up looking good because of the drawstring arrangement. After I bought my first pair I ordered 2 others in different designs/colors. That alone should prompt you not to hesitate buying!! Not sure still-they have a wonderful return policy-that should seal the deal and I swear I am just a consumer like you. Promise!!

Rated 4 out of 5 by from Satisfied Bought these about one month ago for trip to Florida. Like the appearance and the fabric but would not say they are quick drying as advertised. I thought they would dry quickly after swimming and sitting for awhile in the sun from the description but not so and they remained damp even 24 hours after hanging up in the bathroom of the timeshare. I had to pop them in the dryer before packing to come home. Also seem a little on the large side. Ordered medium for 33 inch waist and had to really tighten up the draw string to prevent them from sliding off.
