These are Montbell's lightweight Ridge Line pants. They are easy to wear due to their stretch, and feature a black and gray color block design. Multiple zippered pockets are functional and convenient. I purchased these at a Montbell store and used them for about two seasons in the spring and summer, and they have been stored at home since then. Although it's difficult to see in the photos, there is some minor pilling from wear (see photo 6). I hope you will enjoy them for trekking or walking.
