they're comfortable.  i work out with these without having to be distracted that i'm going to offend anyone.  they're the best underwear ever.  if you want to wear fruit of the loom, that's on you.
cotton goes a long way with me.  the only time - only - that i'll ever wear something else is when i'm working out in the middle of summer in florida, where i get sopping wet.  sopping wet cotton underwear doesn't cut it under these circumstances, and i go with ua:

(i purchased my ua products directly fro ua, and would recommend the same.)  the ua will keep you from getting a rash.  i've learned to use the right tool for the job.
i wear a size 33 waist, and the small fits perfectly.
thank you bvd for all of your quality products.  i will always be a loyal customer.
a final note: for some reason amazon sells these for more than full retail ($18).  you'd get a better price from the mall / jc penny / sears.
a final note: (2015) fruit of the loom purchased bvd, and now bvd does't exist.  another example of why capitalism doesn't work.
