Our most technical active pants built with two of our top-performing and best-selling fabrics; versatile Astroman and renowned Ferrosi. These are perfect for fast pursuits in varied environments and weather.
Named after the same best-selling Astroman fabric of our most popular sun shirts, the Astro Pants take a technical twist on a classic yet comfortable outdoor staple. The combo of our Astroman and Ferrosi fabrics is to thank for making these pants so lightweight, stretchy, breathable, as well as durable and abrasion-resistant - perfect for those off trail sections that require a bit of bushwhacking, shimmying down scrambles, or snack breaks sitting on sharp rocks. Multiple pockets store your valuables while you're on the go, and a gusseted crotch enhances your ability to run, leap, and lunge.

Lightweight, breathable packability. Incredible stretch and softness. Reliable UPF sun protection.
Outdoor Research proprietary Astroman Fabric is a catch-all for the adventurer who spends extended time in sun-baked environments. Astroman products contain UPF sun protection for long days on snow, water, or exposed rock and trail routes. Lightweight, stretchy, and silky-soft, the Astroman is comfortable for all-day wear, while retaining an extreme level of durability for brushes with rock while climbing. Named after the legendary climb in Yosemite Valley, the Astroman was originally built for exposed big wall climbing, but has since been commandeered for hiking, paddling, cycling - even dressing up for an evening out to dinner after the adventure.
Outdoor Research proprietary Ferrosi Fabric makes up our largest, and most frequently awarded, product collection. It hits the equilibrium of being durable yet lightweight, it’s weather resistant yet breathable, and it’s complete with stretchy, easy-to-layer comfort. The Ferrosi line grows season after season, but is most frequently favorited by climbers and hikers for its jackets, hoodies, pants, and shorts. Ferrosi is truly the “do-it-all” choice for any adventurer looking for a layer that ticks three or more items off the gear list.
