Next to some anti-microbial, moisture wicking, flame retardant underwear I wore while deployed, this stuff is the best thing going.  Spending an entire day working outside in the summer AZ sun can be brutal, but these boxers did a better job of keeping the moisture away than any cotton boxers would have.  There were times while traveling that I also tested the "wash and wear" theory, washing them at the end of the day and hanging them to dry for the next day.  Worked very well.  Using a towel to gently wring out excess moisture, these dried overnight and worked great the next day.  The few times I ended up having to wear the same pair for multiple days, they still did a great job of keeping me dry without smelling too foul.  After many positive experiences with my first pair, I ended up buying four pair total.

I also wear these daily to work as well as out working on the property.  Having retired from the military, I now work in an office that requires business casual.  The flat seams and smooth fit make them extremely comfortable under slacks.

All in all, it is really hard find a better pair of moisture wicking underwear.  I can highly recommend these if you don't need a flame retardant capability.
