Outdoor Research’s award-winning Ferrosi pants (trousers)! 

Available in UK sizes 18 to 26 and two leg lengths, the Ferrosi pants are best-in-class outdoor trousers; stretchier, stronger, last longer between washes, and more sustainable than ever before with the same trusted performance. The perfect pair of trousers for hiking, dog walking, climbing, water sports, travelling and anything else where you want to be able to move with ease and comfort.

Improved stretch throughout and more functional features enhance the Ferrosi Pant’s use for climbing and multi-sport adventures, with better recovery for multi-day use.

The Ferrosi’s trusted abrasion resistance, breathability, and weather protection now comes in a 46% recycled material. You’ll find yourself wearing these for weeks between washes, and pulling on for just about everything you do outside. From spring through summer and autumn - you'll be a happy camper wearing your Ferrosi.
