When I first opened the package I was a bit dubious. The pants look like they are made from bin liners! However having tried them out the 10D fabric is much much tougher than it looks, and the pants do a great job of protecting my legs from the wind. The sizing and weight were spot on as well. I ordered a Small 30" leg and they fit perfectly - I can even fit an insulation layer underneath if it is really cold. The weight was exactly 36g on my scales (1.27oz). I am very happy with my purchase.
