I bought these many, many years ago, they are not marked but I think they are Rattlers brand. I wore them once or twice, found them a bit hot and cumbersome and put them in the closet to be lost in time. They are like new and have velcro closures.
I seldom encounter snakes in the woods, am over the hill age wise and not out as much as I once was so I don't need these anymore.
A $25 donation to St Jude will have these headed to your door shipped free. I will need a screen shot of your donation page or your donation confirmation number. Most of all I will need your address, I have had some problems getting mailing addresses for my tillering gizmo St Jude fundraiser.
