Same here. I have a Fox40, a LED flashlight and a watchband compass on a string around my neck and disposable rain poncho in my pocket (I once spent a night on a mountain with a space blanket and I'm not doing it again)
In my backpack I have the classic Dalesman bag although I'm tempted by the heatshield blanket - and as the hairline recedes a spare synthetic/polartec hat.
You might not need the army survival fishing kit necessary if you have to live for weeks behind enemy lines but you can (and people regularly do) die of exposure overnight even in the Yorkshire dales.
