Thanks everyone!
Mike are you using a collar underneath that chin flap or just the flap only? Looks like a tusk could easily slip underneath that flap. I'd like to buy one, but that is my only reserve.
No, I'm not using cut collar underneath it. Just his regular collar and a tracking collar. It's kind of a bad picture because the chain is pulling the chin flap and collar part down and back. I'll have to get some better pics so you can see the coverage. It covers everything a regular cut collar would... plus it's attached to the vest so a tusk can't get in between the two.
Take a look at Silverton Boar Dog's post and you can see how well the coverage is...
