Wonder Cloth is a microfiber cloth that absorbs 8 times its weight in moisture and is incredibly fast drying. It can be used to dry flies, clean your fishing equipment, fly line, or even your bathroom. Our Wonder Cloth products are all made of the same material, just cut and dyed different sizes and colors. The Patches, Boat Towel and Wading Towel all have grommets for your convenience. Remember, the grommet can scratch surfaces. They are washable up to 100 times just don't use bleach of fabric softener on them to keep the integrity of the microfiber. After you've tried them you'll Wonder how you survived without them.
