I've got the pants and hunted this season with them. IMO, they are not as "lightweight" as the name implies, but then again, my definition of lightweight is similar to the 3oz weight of Ex Officio type nylon pants. I heat up very quickly, and normally stay warm when others are cold. That said, they are very quiet, comfortable, dry quick and are lighter than the average hunting pant. Good for just about any situation other than sitting in cold temps or high activity/temps hunting.
