Lightweight and holdup well. Wore them on a few 3 day trips and they are very comfortable. Something about them I also noticed when I travel for work I am a minimalist and only take a carry-on backpack. Take these out of the bag all wrinkled up in a ball and hang them up for a while and the wrinkles go away on there own. These look good for enough for business casual and nights out and that feature keeps me from looking like a soup sandwich.

Great travel pant

I had reservations based on some reviews, but am very pleased with the Ferrosi pants. So much so that I went on to purchase two pairs of the "Ferrosi Transit" pants. They are comfortable in hot weather, breathe well, and so far have held up well. Workmanship on the pants that I've received is good. The in-between sizes (35 waist in my case) combined with stretchy material make it easy to get a good fit. For travel they dry out faster than my other gear.

Favorite warm weather hiking pants

Awesome pant for warm weather adventures. I use these primarily for backpacking in July/Aug and for early season hunts in Sept. They are soft, quite and breathable. Excellent all around lightweight pant. Due to their lightweight they are not going to be as durable as a heavier pant but that is a trade off for warm weather performance. Highly recommend! Sizing is pretty good I usually wear a 32 to 34 and went with a 33 waist in these for a perfect fit.

Not durable

Familiarity:
I've used it several times
Size Bought:
36x34
Height:
6' 2"
Weight:
200

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!!!

Great pants. Lightweight, no piling, and hold their color. I save a couple pairs to wear at work, and have one beater pair that I use hiking and wet-wading.

These pants are lightweight and great for travel and hiking. I used these on the airplane, as well as on the trail climbing mountains in the north cascades. They do not insulate well, nor are they water resistant, but they are so breathable. All around a go to pant in my closet.

Best summer / Hiking pants

Best summer hiking and around town pants that i own, I had the previous version and needed an extra one to wear when the old one is being washed, the previous one had elastic on the back that made them more comfortable but when trail running down a mountain they become loose, I like that these have away to tighten them with the laces without needing a belt. they feel softer than the older version. i like that one of the pockets in the back is now open and easier to slide the phone in.

Great stretchy pants

I recently purchased the Ferrosi Pants, and I couldn't be happier with them! They are incredibly light and stretchy, making them perfect for both outdoor adventures and casual wear. I love how comfortable they feel, allowing for easy movement in any activity. One of the standout features is the four front pockets. They're thoughtfully designed with zipper closures, making it super convenient to carry bulky items securely without worrying about them falling out. This practical storage solution adds to the overall functionality of the pants.

32x36 bought 6’-5” 200lbs

Pants are very thin which is good but also might be too thin to where you would see any underwear line underneath. Finding 36 length though is tough in general. All things considered, give it a try, especially with the discount. The waist line fits true to size. The waist band isn’t stretchy so be confident in your waist selection. Pants are comfy which is nice.
