Erik L.wrote a review of Outdoor Research Lightweight Pack Cover on September 2, 2009
I bought the M. The package states that the average weight is 5.3 oz. Mine weighed 7.6 oz. Thats 2.3 oz more than the average, or 44% more. Is there one that weighs 2.3 oz less than the average? Of course not. The packcover is not lightweight...it is a very heavy fabric, and the sizing is enormous. OR is out to lunch.
