Not durable

Familiarity:
I've used it several times

These pants look good out of the bag and are comfortable. With the drawstring closure, you don't need a belt. Colors are good. Sizing good/accurate. However....the fabric and stitching are of extremely low quality. After just three days of hiking, the fabric is starting to pill and wear thin at the knees and seat. I can see fuzzy threads worming out of the fabric. The stitching in key places like seat pocket and crotch is starting to come apart. My Patagonia Quandary pants (market comparable pants) are >4 years old and have none of these issues after >100 days of wear. If you want to wear these around the house like sweat pants, then buy them and enjoy them for the short time they'll last. If you plan to actually wear these outdoors, don't waste your money. I am an OR fan so am disappointed. Do better!!!

Lightweight and Breathable Comfort

The Ferrosi Pant is impressively lightweight and offers great breathability, keeping me cool even during intense hikes. It’s soft, flexible, and feels comfortable all day long—perfect for both outdoor adventures and casual wear.

Would buy again

The Outdoor Ferrosi Pant has been my favorite hiking and casual wear pant for years. This most recent version feels like an upgrade over my previous pair with strong but lightweight fabric with just the right amount of stretch.

Nice pant for mild weather

Very light weight … waist needs more stretch … seat and thighs are a bit baggy for me

Great hiking pant

I've used it once or twice and have initial impressions

I'm an avid hiker and love this style. Very comfortable, well-ventilated and stretchy. Decent number of pockets.

The perfect light weight pants.

Familiarity:
I've put it through the wringer

This is my second pair since they first came out. I still love them. The pockets are in the right spot, cargo pants done right. Very light, very tough, and comfortable.

OR need to fix the sizing

If you're considering buying these pants, I recommend trying them on in-store first. OR has made fitting extremely complicated; it seems every single piece of clothing is a different size. I bought these pants in the same size as my previous purchase 30' , and they are too small.

Short is still long

For those customers with shorter inseams, 28" or shorter, disregard this product. Backcountry labeled an inseam of 30" as short, which is ridiculous.
