CrackShot's Snakeguardz are $70 gaiters made from tough, 1000-Denier nylon. They not only keep snakes from slithering up your pant legs, but prevent bites.
Cool stuff, but even cooler is the fact Ben Meadows says the gaiters are "strong enough to stop a 12-gauge shotgun blast at 20 yards."
I would hate to be the dude who tests these.*
*Yes, I realize no one actually wears them and gets in the line of fire.
