These are by far my favorite hiking and climbing pant. They are a very comfortable stretchy material.
My first pair I got I purchased a 6's according to the size chart (Those are the ones in the picture). I am usually a 4-6 or 27 depending on brand and fit. I definitely should have gone with the 4's, which I bought the second time around and fit better. The 6's I can wear with a belt fine and are actually kind of nice when I want a looser fitting pant but they are stretchy so the looseness doesn't really matter too much.
I also have slightly longer legs, usually somewhere between a regular and long length in pants so when getting the 4's, I went with the long length this time to see if I liked them better. The longs were literally like 4-5 inches longer! WAY too long to the point where I was stepping on the entire pant bottom. I got them hemmed to my perfect length now and they are great.
Very stretchy, flattering, lightweight, breathable.
The roll up snaps are really nice too!
The buttons on these pants are terrible. Within a week of wearing them one of the buttons to secure the pants on your waist just fell off. A few days later, the other one fell off!!! They are sewed on so badly, thankfully I had access to a sewing kit at the time and was able to sew them on much better and haven't had an issue since, but this has been an issue on both pairs I own.
The double button closure it kind of annoying too. It would be much simpler to just have one button, which I might end up altering myself as well.
The other thing I am not a fan of are the pockets. The snap buttons on the back pockets are not the most comfortable to sit on hard surfaces with. Also, the only other decent sized pockets are the two front ones, which aren't very deep at all, definitely not for an iPhone 6 to fit comfortably in without being annoying. There is a small zip pocket on the side, which is nice, but it really isn't too big.
Very comfortable pants! Minor issues with the buttons and pockets (why i gave 4 not 5 stars) but still one of my favorite climbing & hiking pants out there!
