I bought 2 pair of these shorts for biking and gym use.  These were the best deal that I found on Amazon, with shipping included.  They are not see through, and come down to just above my knees.  The waist band tie does not have 2 ends, but rather 1 continuous loop, so no worrying about the ends going back into the shorts!  It does make it a little harder to tie though, but not a big deal for me.
