from the 'Too Much Information' department.
My crotch sweats, and this is really gross. As a young 'un, I discovered the solution:  'bikini briefs'. Well, I recently had to replace mine, and discovered that these things are now called 'sport' briefs. Whatever.
These are my daily companions. The assorted package I got had:
striped heather, black (2), grey, heather, and striped white. A very reasonable dark, conservative mix of color.
A reasonable, everyday value.
