Pros: High quality material, dried quickly, and very comfortable.
Cons: No built-in bra (not the worst thing in the world, I just assumed most singlets had one), small back pocket, and the white color isn't the most flattering when wet...though it does keep you cooler than the standard black.
I wore this for my first Ironman 70.3 and it served me well on all three legs of the race :) Would probably not pay full retail price for it, but since it was on sale it was a great buy!
