Get It Before Labor Day Weekend—Order With Free 2-Day*by 5pm MT 9/2/15

The SmartWool Microweight Brief uses fine merino wool to gives you over-the-top comfort whether you're bounding over a backwoods trail or trekking cross-country. Merino wool gives you better comfort and temperature-regulation than polyester and comes without polyester's infamous funk, too.

  • Flexible merino wool helps your body regulate its temperature
  • Touch of elastane enhances the fit and helps the brief hold its shape wash after wash
  • Merino wool's natural antimicrobial properties keep these briefs fresh even if you have to skip a washing
  • Form-fit cut is built for action
  • Fully functional fly is great for nature's emergency calls
