Jerven bag? Which one and any accessories?

[Omega]

I am thinking to buy myself Jerven bag - leave it in the car boot in case the car breaks down, use as ground sheet on a beach or for a picnic, use it in cold evenings while camping, hunting or fishing (I was recently in Ilfracombe, there were lots of tourist walking around in robes like Jerven when it was cold), maybe for sleeping in the car, maybe using as a bivvy bag while camping and a worn shelter to change wet clothing on the beach. And, of course, for an emergency - I hope we will have gas during the winter, but if we don't, then, like people in Siberia, I could make a small shelter inside the house and stay warm there
I wonder what Jerven bag I should buy? And should I get myself accessories, I am especially wondering about tent end pieces? eBay has quite often Jerven Extreme bags , but I was thinking about King Size because of the size, or Original because of the price, plus they can take tent end pieces. However, at the same time, I think a tent might be useful only if I intend to build a shelter at home in case there is no heating at home - it is useful for military, but I am not in military, though things nowadays can easily change
Like the original for the price, but, if you use something often (I do not know how often I will use it), then going even double the price might be better value for money because of comfort as original seem to have problems with evaporation, while more expensive models don't. Then I do not know about the loft - as I understand, the main ones are 60 and 170, but there is also an option for 200 (think it might be some special order)
Also wonder how I could use it in my daily life at home - I like living on the floor in my room, I know I can use it as a blanket, but is it comfortable, or I had better get something like Snugpak?
Thank you

I have had the Jerven Bag Exclusive along with 2 different weight liners for a decade or more now.

I've never slept in it as a bag (yet) but used it on many occasions as a groundsheet, as a cagoule, as a windproof and / or waterproof shelter, as a tarp, etc. It has also been used on two occasions to shelter a casualty (not me) until the emergency services turned up.

Mine lives in the car fulltime along with the heavier weight liner, amongst other goodies. It migrates to the rucksack according to plans for the day.

Both liners are also used variously. I have slept in them.

Just got myself Jerven Extreme Bag. Well, it is very thick. It is a proper blanket and comparable in size to a sleeping bag.
Well, I probably should get myself another one that I can convert into a tent and keep this one too

This is confusing, but Extreme only comes in 170g. Mini, Thermo, Hunter and King Size come only in 60g. Exclusive come in both 60g and 170g. There is one bag that come 200g, but I saw it only once on internet
170g is a massive overkill for the UK imo

Thanks for that, might take a look at a 60 if funds allow sometime

I've got 2 Kingsize. I use one for hammock camping.
Got myself a hunter and exclusive.

I mix and match for when required.

I now wonder if I should get something lighter instead, maybe Hilleberg Bivanorak, because Jerven Extreme takes so much space. Anyone had an experience comparing them?

I have the Särmä TST Thermal Cloak in 67g/m2, they’re quite a bit/ a hell of a lot more affordable than the Jervens. I’d say, the main difference is, as far as I know, the Jervens’ zips are waterproof, the Särmä‘s zip is not. Personally, I think it actually helps with condensation, you just arrange the cloak so it’s not an issue using it in the rain.

I’ve been think about these as an alternative to the Jerven. But too pricey for me as break down kit though.

An update - I had a small family emergency and slept in my car when outside temperature was 4 degrees Celsius. My Jerven performed really well - I was in a small car on the rear seat, put part of the bag underneath (because I felt the seat was cold) and covered myself with the rest. I felt very warm though tight sleeping with interruptions for about 6 hours (the longest uninterrupted sleep was about 2 hours), I felt cold quite quickly if I put my leg or arm out, but the bag was quite generous to cover me fully with extra. Anyway, it definitely works in the UK if you are out of wind

I bought several over the decades, original (carried often, used little), original thermo (carried less, but used more often) and the extreme (carried rarely, used never). If I lost all of them I’d miss the thermo original the most. While carried as an ‘emergency’ item, the thermo original gets pulled out for lunch stops and as an evening camp warmer and as a blow up bed ‘sheet/warm liner’ too, very handy. The original is small and light but clammy in use and I avoid it casually. The extreme (rescue orange) I bought as a winter emergency item only, thankfully never needed and it’s heavy/bulky to carry, still I like the overbuilt quality and fancy giving it a go in cocoon mode one of these days! All in all great items, well made and despite some abuse (leaving in a hot trunk and using them as sit cushions is not great for them) lasting well otherwise.

I think I am right in saying that Arktis did their own version or made one with with Jervan in French CE Camo. They might be worth a look. There is one on flea bay today.
