WOW love these pants, very comfy, warm also for a shell pants, to my surprised there a liner inside, in the knee and bums area its like a soft very thin fleece liner, the rest of the pants has a nylon liner, I am not a fan of this liner but it keep me warm in cold weather, the pants are very long I got a Large pair, I am 510 but if you like the bulky look they are great, the bottom cuff elastic at the legs are way to loose and there no adjustment. The nice part is the 4 pockets in the front very well designed, the durability of these pants will be amazing due to the strong 3L Gore-Tex. Overall good pants.
