This is easy to use, fast drying, and odorless. It has a nano-technology formula that creates a invisible barrier on the surface of my items, repelling liquids and dirt. It does not affect the color, texture, or breathability of my items, which is good but always test first please. I love that it is eco-friendly and cruelty-free. It comes in a 125ml spray bottle that can cover up to 5 square meters of fabric. It is very easy to apply: I just shake the bottle well, spray evenly on the clean and dry surface of my item from a distance of 15-20 cm, let it dry for 24 hours, and enjoy the protection.
