I keep a limited stock of this durable fabric that's suggested for rugged outdoor use. It is a breathable (like cotton) acrylic fabric that is water, fade, mold, mildew, and stain resistant.

There are other colors available that aren't shown here, so please ask and I'll see about obtaining it.

Water-resistant/waterproof fabric is considerably higher in price than the 100% cotton.  For a working service dog vest made of this fabric, please add $10.00 to the base vest price.

Please note, this fabric only comes in solid colors, not limited to what is shown here.
