Spit? Condensation? Whatever you want to call what empties from the water-key or spit-valve on your brass or wind instrument, IT'S GROSS! Now with The Spit Catcher, there will be no more puddles of spit after each playing session. The Spit Catcher is made up of three layers of high quality fabric. The top absorbent layer can soak up to 10x its weight while the waterproof layer underneath keeps your floors clean. When your music session is over, fold The Spit Catcher into the integrated waterproof pocket on the back. This will keep the inside of your case dry as well. The Spit Catcher is infused with SILVADUR 930 Antimicrobial, a polymer-based antimicrobial that inhibits the growth of bacterial odors. The antimicrobial properties are only for the protection of the product and do not protect users or others against bacteria, viruses, germs, or other disease organisms. Always clean and wash this product thoroughly after each use. Wash and dry on medium settings. A must have for every Trumpet, Trombone, French Horn, Tuba, Euphonium, or Bassoon player!
