Have you ever almost mistaken your dog for another animal when they come charging out of the woods... bushes are coming alive... adrenaline starts flowing... when you think it is that monster BUCK you have been waiting for? This is the ticket for you!! What about the SQUIRREL dogs or the COON dogs? Need to see them? This will work for you as well... This is a single layer of Day Glow Orange. The same thing the three layer vest are made out of, but only one layer. Three buckles keeps it in place, and Day Glow Yellow straps allows you to adjust it to the proper fit.
