I like the elastic waist band, suit dries pretty quickly, nice colors.

Bought these in a large for my 6'3" 175 lb 18 year old and my 6' 0" 160 lb 15 year old is now fighting him for them.  I ordered a couple different Speedo brand suits to try and it seems these fit best.  They have a little stitching and elastic at the waist which helps them keep from sliding off a skinny kid, but they can almost pass for board shorts (which have no elastic and can ride too low causing the  "refrigerator repairman" problem.  :-0).  These also have a mesh lining, which is a must unless you are going to wear compression shorts underneath.  Speedo has several other trunks in this style, with different fabric, if these doesn't float your proverbial boat.
