Underwear for Out There

The active fit, ultralight mesh, and smooth waistband make the new Sport Mesh the most comfortable performance underwear you’ll ever put on. They feature an antimicrobial finish and highly breathable mesh to keep you cool, fresh, and comfortable whether you’re exploring Argentina or your local trails.

Performance Mesh

Our new ultralight mesh fabric is highly breathable, odor resistant and super-fast drying for easy care anywhere. It also has extreme stretch for maximum comfort during any activity.

Ultralight Sport Mesh fabric for maximum mobility & breathability


The open weave mesh allows for maximum airflow to keep you cool and comfortable


An antimicrobial finish eliminates odors in fabric, and you only need two for any trip - wear one and wash the other

Moisture wicking

Wicks moisture away from skin, and dries incredibly fast for comfort and easy care on the road

Fit for Adventure

The active fit and lower rise are perfect for any activity where you need performance and mobility. The stretch mesh, flatlock seams, and smooth waistband are more comfortable than wearing nothing at all.

The New Favorite

“Possibly the best underwear I’ve ever owned. I came to ExOfficio via Tim Ferriss’ blog, and his recommendation was spot-on. All the features of this boxer brief are top quality. You can run, lift, bike, whatever in total comfort. And they will take a full day of sweating without starting to smell (unlike a lot of other “high performance” underwear out there). Complete, total satisfaction.”

Easy Care on the Road

  • 1. Wash in the sink with soap and rinse (or wear them in the shower!)

  • 2. Wring out as much water as possible, then lay flat on a dry towel.
  • 3. Roll the towel up with the underwear inside and squeeze to absorb remaining moisture.
  • 4. Hang dry in a well-ventilated area. Your underwear should be dry within 2-4 hours, depending on humidity.
