Can you? if not where can you find it? i know when you free the town theres a chance of one of them dying while you fight that creature but i was at max carrying capacity so i couldnt get the armor plus it wasnt a FULL set.

Cant craft it only way is for one of them to die.

No.
Nor can you improve it.

The hunters have all items except the gloves...
