A new trader in each of the faction bases that sells "hunters" gear at a high price, his inventory could include;
Pelts of all varieties, chitin scraps, knives, bear traps, fibers, wood, basic leather armors and jackets, stealthboys and stealth guns.
In return he could buy high condition knives, stealth guns, stealthboys, bear traps and leather armors.
There are times when hunting for these mats personally is fine, but many times where convenience would be appreciated. The traders at the front of the bases and even the high reputation trader at times have these kinds of materials but it is infrequent and random, and I thought it would be nice to have an option to buy them in relative bulk (at a boosted price).
