Unlike normal invisibility cloaks which just have either disillusionment enchantments placed on them or are woven from demiguise hair, This cloak never deteriorates and offers complete shielding from any form of detection. I tested this with the age line around the goblet, the cloak can walk through wards as if they didn't exist. I always thought that the hallows were just powerful items enchanted by the best of their time but now I'm beginning to believe they were gifts from death because here is a cloak that could very possibly hide you from death itself. I now have my entry to the manor.
