Both, Sandstone and Duck materials, are made of 12-ounce cotton. Both materials will keep you comfortable and protected during work or every day wear. So what is the difference?

The Sandstone Duck is pre-washed, leaving the material much softer and worn-in feeling than the Firm Duck. Because it is pre-washed, it is not the best option if you need to repel water/ rain.

The Firm Duck is treated specifically to provide a water repellent -not water proof- outer shell. With this treating process, you are left with a much more rigid/ stiff feeling material that will break in over time. This material will need to be treated again if you would like it to maintain it’s water repellant property.
