Over a long career of performing, chances are you're going to end up playing an outdoor gig. And when you do, without fail, your music will take an airborne field trip during your 32-bar solo. You'll try clothespins; you'll try binder clips. Your music will chuckle at your naiveté. But not with Portastand's Wind Resistors. Sold in pairs, they stretch across the entire music stand horizontally - top and bottom - to hold your music down and keep it there. With their powers combined, they can even be used as an awesome music stand seatbelt for your favorite tablet.
