My husband recently started a new job working in a building without air conditioning in this crazy summer heat wave.  After just 2 days complained of some "chafing" after sweating while working 10-12 hour shifts.  I set to Amazon to research some moisture wicking briefs for him and stumbled upon these.  We bought a pair and he loved them and had to order 6 more pair.  They keep him cool and dry where he needs it and wants to phase out all his old cotton briefs for these.  He also says the support is perfect as well.
