I understand the the OP's meaning but the title isn't accurate. This person does not appear to have had much gear on him, aside from his lack of actual skills.
A good tent and sleeping bag would probably have saved his life, regardless of his survival skills.
I totally subscribe to the 'skills before gear' philosophy. It's just that with even very rudimentary camping skills (most people will succeed in erecting a tent or lighting a camping stove unless there's a hurricane blowing) a bit of proper camping kit would have saved this man's life.
Even someone with little to no training with a tent and sleeping bag may have survived, knowledge is great but some equipment does help and would have helped this guy. Even a Survival expert that falls in ice cold water may have a hard time getting a fire going and stopping hypothermia.
