Making your own REAL Jerven Bag...?

Is it the original one which is just the material? And wasnt there one with a removable liner? [Which some people preferred]
The warmer ones come with a primaloft padding. They are more expensive.
I think this is the same material the original one is made from. Just the windproof/waterproof outer with the reflective material on the inside but without the padding.
Anyone know?

Dave, there are at least three types - just the bag with no insulation, bag plust fixed insulation, and bag plus detachable insulation.
There's no need for taping seams as there aren't any in a Jerven bag, it just has three long zips along the edges and a couple of small zips for arm holes. You could do without the arm holes but I find them very useful, they add a lot of flexibility.
Making one might be worth a try, but I don't know how easily you can get the zips. They're on a par with the zips on a lot of military kit.
Fantastic bit of kit.

How is the detachable insulation attached?
What form does the insulation take? Is it something like Thinsulate in a polycotton shell?
The zips wouldn't be a problem.

Dunno Liam. Never seen one up close. Popular though.
Thats handy to know. Thanks. I was gonna ask if anyone had a pattern, or a design etc.
You could be right. Could send an email, but its the kinda thing which would get lost in translation. It could just be that most of the price of the bag is in the labour costs. I really dont know.

A piece of the fabric 300cm x 200cm would make a bag of 150cm x 200cm, which is roughly the size of the Thermo King Size bag.
It is a good price.

Labour costs and developing the material I believe.
The insulation is similar to a poncho liner
It zips in so there are two zips besides each other on the three sides.
Plus zips aligned with the arm holes.
In truth and now I am gonna be hounded for sayin it I think they are over kill for UK temps. Nice kit very Gucci but more suited to ridiculously cold environment s
Course if someone gave me inequality I wouldnt say no.
Material looks good for a winter tarp. Built in reflector

Does it have to be in the same colour as the Jervens bag.
There was a thread started by BareThrills about a custom jervens footprint.
From what I recall he sourced some material very similar with a reflective inner coating. This could be made into a similar thing by adding an insulating layer.
This material as the jervens is waterproof but not breathable.

bilmo 5 the insulation inside a Jerven is Primaloft in differant thickness depending on the model.
I have been toying with using one of the 'original' space blankets for a DIY Jerven bag. Just haven't got round to it yet.
Those St Johns ambulance/RAC blankets that Steve posted up in another thread may do the job?

I think this Norwegian Bushcrafter has bought some to make into a wilderness camp chair.
See the subtitles at 2:38 Says he bought the fabric from Jerven, and it has a reflective inner.

Thanks Dave.
People rave about them so must be a bit of a bushy grail!
Wonder how breathable compared to goretex or army mvp?
