RE: Hat Covers
just a thought, but why not get two pieces of fabric(square pieces), one camo to match your hat and one blaze orange, sew them together and then sew one end of the new fabric into the back of your hunting hat, when you want to walk and have the blaze orange, just fold it over the hat and attach it with velcro stripes sewen into the hat and fabric, and when you want camo, just fold it up into your hat. You get the idea. You could even put a button like for a shirt on your hat and cut a hole in the fabric to attach button when wanting blaze orange. that way you can let it dangle behind your head instead of tucking it into your hat. and it would be camo on the side showing when dangling behind your head.
