Your feedback inspired the new and improved Ferrosi. Long-time favorite features are back, along with a new sustainable fabric and better-than-ever fit. The new waistband retains its shape and comfort without stretching out. Check the size chart for your perfect pair, and consider sizing up if you prefer a classic Ferrosi fit.

Easily go from pants to shorts and back to pants again with the easy zip-off legs of the Ferrosi Convertible Pants. Pant legs can be stowed away in your pack mid-activity without taking up the bulk and inconvenience of a separate pair. Plus, these are made from their long-time award winning and best-selling Ferrosi fabric. With improved stretch throughout and more functional features to enhance climbing and multi-sport adventures, these pants are ideal for just about everything outdoors and will last for weeks between washes. Not to mention: The same trusted abrasion resistance, breathability, and weather protection now comes in a 46% recycled material. On rock, trail and water, from spring through summer and fall - you'll be a happy camper if you wear your Ferrosi.
