My cheapo just in case cagoule weighs in at 120g Susanne and it does go in a pocket. It's much more practical than trying to hold down a sheet of stuff that wants to be a kite.
I opened up one of the shiny sheets on a hillside and the damned thing was impossible to do anything much with.
Someone did a review not long since about the shelters made from the same stuff that we can get for £1. Even that would be better than the sheet.

The NO was in response to yours. It was a quiet hint.
Fire and plastic is a bad idea, but then, each to their own.
FIRE & SPACE BLANKETS
I understand the general principle, yes.
Space blankets are made of LDPE which is actually one of the less terrible plastics in terms of fire behaviour
In fact I have lit one of these on fire from a candle to see exactly how close the candle needs to be and what happens next. (Not as bad as you may think...)
Still, you don't want it to burn.
Obviously.
RISK EVALUATION
Each person should evaluate the risks for themselves. I would still rather have a manageable risk of a tiny controlled flame inside my sheet than the risk of death by exposure.
But like you and I both have said, each person should make up their own minds.
In fact, my personal view is that MOST people have absolutely NO BUSINESS being in any kind of mountain or wilderness setting without the full backpack of survival gear.
Fell running
Sea Kayaking
Mountain Biking
and the like are risk sports for which the PREREQUISITE is to be able to make proper comparative and situational risk assessments.
I sincerely hope none of you end up with it melted to you.
Me too, and I also hope none of you ever need to make the assessment of whether you need to do this or suffer from exposure...
Looking at the accident stats in UK, Europe and USA, though... a disproportionate number of people get in trouble from exposure on the hills every year.
Peace
