I have never heard of a "kayak socks" and I kayak 365 days a year.
You can build a blind and hope you can cove enough. We like to level the blind 1" 2" off the water as the raffia will drag on the water in a retrieve and slow you down. My buddies did that can he had to give it a trim. You'll just have to hope they are flying high and don't notice the yellow orange at the water line. Or maybe buy and earth tone kayak as an extra, hunting kayak.
"If you can't have fun doing it, it ain't worth doing." my motto
There is nothing better than hunting with friends and then crackin' a couple of cold ones afterwards.
