I was told when I purchased these that I would never wear another pair of underwear - I dismissed the comment as typical sales garbage. They were right - after I wore the one pair I purchased, I immediately went on Amazon and purchased about 15 pairs of these bad boys and threw-out all my other underwear. They feel amazing and fit perfect - they don't ride or bunch up and the band stays flat and in-place. The platinum fly are more silky than the Fiesta or 24/7 - but still feel awesome and keep me cool "down there". Get 'em - you'll love 'em.
