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
