When searching for a comfortable jock there are three issues:  the straps not cutting into you; the waistband not curling over; and the knit being breathable.  I found this jock to satisfy the first two, but not the third.  There use to be a jock on the market with a mesh cotton pocket that was so great, but not to be found on the market any longer.  Papi's jocks are soft, well made, and, at least, a fairly breathable fabric.  In really hot, sweaty conditions, or under a bathing suit, these jocks hold water (and dry too slowly).  But to be frank, I have found nothing else to rival them, so I will buy these again.
