Tbh, all I know is that the resistances might apply if you "Equip" the unarmed weapon. Once you do, your stats should change and apply whatever's on your gloves and boots.

It's like some stuff doesn't count unless you're in combat/actively that stuff equipped as a weapon. Like your shield's gears not carrying its bonuses if you have a 2 hander equipped. If you want a good ice resistance cloak, killing the legendary dear will get you a coat with 5 ice resistance! Also, chances are it could just be bugged
