This thing is completely see through, people who say otherwise must be related to Mr. Magoo! I had to wear underwear underneath, otherwise it is too embarrassing. All this thing needs is a little pouch or something at the front then it may be OK but it is see through and my pale skin is still pale. I think the sun needs to be exactly 90 degrees above you for this thing to work.
15 yr. old (very tall 6ft) loved the length..we had to add boxers to be able to swim in them...but overall he felt they were 'cool'!
