All of the 1.1 oz olive drab DWR I've found in Walmarts across the country has been 48" wide or less. Most of the other fabric is 60" or more wide, and I've found regular 1.9 oz untreated ripstop in olive drab. Every now and then I've seen other 48" wide fabrics, but they're usually also available in bigger widths if you keep looking. But I've never found or heard of anyone finding OD DWR at Walmart that's bigger than 48". I wonder why it's that consistent across the country.
Anyone found full-width 1.1 oz olive drab DWR? Sure would be helpful for a few of my projects.
