Beta AR Pant Men's

All-Conditions Waterproof Pant for Variable Mountain Weather.

The Arc'teryx Beta AR Pant is built for moving through constantly changing mountain conditions—rain to sleet to snow and back again. Compared to the standard Beta Pant, the Beta AR uses GORE-TEX Pro with Most Rugged Technology, delivering significantly higher durability for harsher terrain, heavier use, and longer days out.

Articulated patterning, a gusseted crotch, and articulated knees and seat provide freedom of movement for hiking and alpine travel, while WaterTight™ side zips with drop-seat functionality add convenience without removing layers. Keprotec™ instep reinforcements protect against crampons, ski edges, and boot wear, and a hidden RECCO® reflector adds an extra layer of safety in search scenarios. This is the Beta pant for users who prioritize durability, protection, and versatility over minimal weight.
