I don't know, properly made chainmail suit is bite and scratchproof. Might be able to wrestle the tiger into submission. Though the weight of the tiger is going to be a VERY HUGE issue. Give me a spear and I'll be willing though.
That should make for an interesting YouTube video.
On the condition that the tiger is a healthy adult in the wild, hungry, and has never been captive, and someone is standing nearby not to interfere but to hit the upload button after you’re slain.
Human has no chance wrestling an adult tiger.
Second, video proof. I know this kind of things probably aren't taped, because the people are busy fighting for their life. But, still, I'd be skeptical before I see some proof, that a person fought and killed an healthy adult grizzly (or some other comparable types) without a firearm or trap.
