Arc'teryxPhase SL Brief - Women's

These briefs were made for walkin.

Just call the Arc'teryx Women's Phase SL Brief your travel undies whether you're backpacking, mountaineering, or flying to another city—and on those random occasions you actually stay home, feel free to wear the Phase then, too. Its unique fabrication is hydrophobic to prevent water absorption when you're traveling under wet weather, and it breathes, wicks moisture, and dries quickly for warm weather adventures.

  • Travel undies for natural and urban sprawls
  • Hydrophobic fabric wicks moisture, dries quickly, and breathes
  • Gusseted construction assures full mobility
  • Smooth flatlock seams reduce chafing

  • Fit: True to size

These panties are fantastic. Very breathable and good quality material, plus they look cute too. I would say they are pretty true to size, but if I was generally in between I'd order up.

Favourite Pair!

I bought these for the wifey before her trip to Asia she reported that they were by far her favourite pair! Great fit that was true to size, fantastic materials and everything that you can expect from Arc'teryx. Comfortable and breathable A+
