In my system, there is no MAXIMUM limit for survival equipment - there is just the right compromise between season, location (How far to civilization? How rugged terrain? What kind of activity/risk level do you plan for?) and how much you're willing to carry. I strive to find the MINIMUM size and volume for each trip.
In my climate, clothing is absolutely essential to my survival - even in summer. (Even more in summer, because the temperature may drop from 80's to the 50's at no notice at all). Usually, extra clothing takes MUCH more volume and weight than what the ETS community would typically consider my "PSK proper".
My typical outdoor clothing will include the Doug Ritter PSK (tweaked a bit, see the "PSK sharing center" thread for details), a fixed blade knife, a heavy duty thrash bag and a rain poncho. For fire I have a lighter and some vaseline cotton balls. This all goes into cargo pockets on my trousers. My anorack (goretex equivalent shell jacket) includes a whistle, a ultra-minimalistic first aid kit and minimum a merino wool buff (usually gloves and a wool cap as well).
Except from my local jogging trips, I always bring a daypack. "Daypack" may be anything from some el cheapo satchel the size of a small shopping bag to my 55 litre Bergans pack - or a small hip pack. The size of the pack is dictated by whatever else we're bringing and how much extra clothing/equipment that is needed. Obviously, I bring much more during winter than on a hot summer day.
The survival contents of whatever daypack-of-the day is at the minimum my bivy bag, which is too big to fit comfortably into a pocket, some warm clothing and whatever food or drinks I care to bring that day. (Drinkable water is everywhere where I live, although in solid form during the winter - in which case I need to prepare for that).
How can I possibly separate my pack into "comfort" and "survival" components? I will put on the extra layer during breaks - but the same extra layer of clothing will be absolutely paramount to my survival if I must spend an involuntary night out in the woods.
In my view, the question of what MINIMUM gear to bring is much more interesting. But I guess that is just rephrasing your question.
I guess the closest I come to answering your question is the contents of my cargo pockets (lighter, cotton balls, knife, modified Doug Ritter PSK) and my bivy bag. But that is nowhere near my maximum limit for the sum of gear + clothing + food/drinks I'll bring.
