Double rainbow - WHAT DOES IT MEAN? It means twice the gold on the other side, and the leprechauns are fighting each other for it so you can sneak over and take a few coins.  Unicorns are prancing in the distance, the sun is shining, and all is good with the world. Who doesn't love a rainbow?  Elastic cinch adjusts to hold drinks from 1" to 3.25" inches diameter.  Clamps to bars, seat tubes, or anything up to 1.5".  360 degree rotation for flat bars, curved bars, or vertical mounting.  Shock absorbing design adjusts to the size of the drink and smooths out bumps.  Works great for Bikes, Strollers, Boats, Wheelchairs, and more.  Made in the USA in beautiful Denver, Colorado!
