These are a much thinner fabric than what I expected which for my purposes is better.  I have added ocean swimming to my workout and these go from run to swim to run very well.  I wear lycra shorts under them so I don't need a liner.  The pockets turn inside out when I swim but I remedied this by tucking them into the top of the lycra shorts.  I like the pockets they hold my mp3 and a small shammy while I run.  They dry quickly and rinse out easily also.  If I was redesigning them I would tack the bottom of the pocket to the leg to keep them from bulging out in the water.
