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.
