if you actualy think about it though no zombie other then weapon weilding ones would realy be a threat
taking decay intoi account a zombie would be slighlty weaker then its human counterpart and as even the strongest human cant bight through jeans or leather all a man wiould have to do is wear a thick jacket a pair of jeans, gloves and a balaclava and they are safe from 90% of zombie bites as for the other 10% they can only effect obvious locations (wrist ankles face) so would be easy to ward off
