Weighing in with 12oz canvas construction, the Featherbeds are a substantial pant. Not super heavy, "selvedge denim," feeling or anything like that, but enough to feel sturdy. There is a bit of stretch to the fabric used, but also elastic sections above the knees the butt to remove squeezing and tension points that result from, the seated riding position. This is a huge factor for me and something that helps me stay in the saddle much longer, as I noticed with other thicker pants I would start to lose circulation in the knees or get a squeeze around the waist after sitting for too long. The elastic section alleviate this and make for a very comfortable pair of pants.
