So, after carrying for ~16hrs/day at the House and Senate hearings - I noticed something...I was wearing the wrong underwear (*snip* insert joke here */snip*).
I'm normally a boxers kind of guy - but the pleated cloth waistband combined with the elastic and IWB holster was chaffing the heck out of my right hip. I used to wear a photographer's waist pack with lenses and a variety of gear around my waist, and I used to have the same problem at long weddings. I switched to a flat waistband boxer brief (what I now jokingly refer to as my "Tactical Underwear")...and problem resolved itself.
Just a thought as you choose undergarments. Carry on!
