Sleeping bag knitting help requested.

Hello dear Knitters,

I would like to ask you lovely peple for some help on an knitting project I have in mind. As we all know, the sleeping bags in store are all made from synthetics. I don’t want to sleep in synthetic conditions on a long backpacking trip. So I would like to make my own lightweight (2.5 kg) sleeping bag made from organic materials.

For the shell I would like to use organic cotton with a very dense stitch (note: I am not familiar with knitting vocabulaire)
The Insulation will be made of organic merino batting
And the inner liner will be lightweight cotton.

See my influence here: https://www.woolsleepingbag.com/shumanns-15-f/

I would like to ask advice on good and cheap materials. well, the important thing being that the product is good but if it is also cheap also nice.
And I am wondering how I can get started with this project, what do I need.

Thank you very much!
Casper

Welcome to KnittingHelp!
You might look at some of the cotton yarn from Knit Picks. It’s nice quality at a reasonable price. Keep in mind the weight of the yarn because a dense knitted fabric is going to use up quite a bit of yarn. That might be heavier than you would like.

A cotton blend might be something to think about.

I was more thinking about buying a nice fabric for the inner and outer shell, and then stuffing that with wool batting. any tips on how to do this properly, without the wool displacing?

Thanks

Ah, more like a quilt then rather than knitting. You’d need to stabilize the fabrics and lining by stitching through all 3 layers. I don’t quilt but this might be a video to get you started:
