Ex-Officio Give 'n' Go briefs have gotten rave reviews. I use the female version. I discovered them about 6 years ago and tried them for backpacking. I soon threw out all my other briefs and have worn only Ex-Officio all the time ever since. The original three pair I bought 6 years ago are still almost like new, too, so they're well worth the price.
May your trails be crooked, winding, lonesome, dangerous, leading to the most amazing view--E. Abbey
