Fit - 5 Stars / Comfort - 5 Stars /Durability - :(
Fit - 5 Stars Comfort - 5 Stars Durability - :( These pants are great for on trail hiking as long as there are no thorn bushes or anything with pointy tabby things. My left leg caught some thorns and pulled a lot of threads. To be on the safe side, don't wear them anywhere you wouldn't wear shorts.

Best pants ever
What can I say except the comfort, pocket design, and style are all exceptional. Sizing was spot on, and they did the job well.

Great pants, kind of snug
The size of these pants is actually your waist size in inches. If you have a 38" waist, get a size 38. A size 36 actually has a 36" waist. Most pants nowadays have glamour sizing. Size 36 Levi's usually have a 38-39" waist.

Yes, I’ve only worn these on a handful of consecutive hikes, and yes I’ve noticed some pilling of the fabric even before their first wash. But they fit great and they are insanely comfortable, and feel very durable yet lightweight and tactical/technical. The deep jeans-style front pockets don’t bother me like other reviewers. And I thought maybe I’d miss the convertible pants/shorts these are replacing, but I could wear these all day. And I find the low-profile leg pouch and zippered back pocket to cover the bases. I don’t want to use my pants as a giant storage container anyway. They are very cooling and provide all-day UV protection. I can already say I’d buy these pants again and again.

Just returned from 3 weeks in Italy and the Alps. The pants fit well and were comfortable. I appreciate the zippered thigh pocket, which stores my phone nicely without impairing movement. Lightweight fabric was easy to hand wash and dry to keep fresh clothes throughout trip.

Go-to Warm Weather Adventure Pants
I purchased two pairs of these about a year ago. Since then, they have been on trips in 7 time zones spanning 2 continents. They're a near perfect combination of comfortable, breathable, quick drying, water resistant, and packable. They have held up well for a lightweight fabric and I would recommend for any warm weather activity that does not require hard use clothing.

Absurd Price
- Familiarity:
- I've put it through the wringer
They used to be ~$95 now they are ~$105. Absurd price IMO. Wait for another 365 days and OR will let you pay ~$115 for them!

Awesome pants!
Fit is great, weight is great, performance is great. No complaints other than a little pilling of the fabric on the knees from use/washing.
