Arc'teryx Women's Beta Pant
Description
Meadow becomes mountain, sun becomes rain, then snow - as you travel, landscapes vary, weather shifts. Waterproof, windproof, and breathable, the highly versatile Beta Pant carries you across this range of conditions, terrain, and activities. Its durable GORE-TEX fabric features GORE C-KNIT™ Backer Technology for enhanced comfort, quiet, and breathability. Full side zips make on-and-off easy, the regular fit is clean but allows room for layers, and articulated patterning frees you to move.
