Not the same -- nylon woven netting. It'll have very little insulation and wind blocking value.

If you want good prices on roles of this stuff, you have to go to agricultural vendors.

Here is 6' by 250' for $30 -- I think this is the same fabric weight as those plant bags:

They also have heavier weights. I think at least 1.5 oz would be what's needed to make it durable enough if you're putting the time in to sow it.



Translates to about $0.25 per yard (of 5' wide fabric) through that vendor.

Frogg Toggs are also made with a backing ply similar to this fabric -- so that's another place to go for a reference. Frogg Toggs do add that water resistant outer ply, so don't expect the same water resistance.

A little heavier but much more durable, a two ply poly pro material is the Dri Ducks Poncho... vailable stock or as modified as a Weather Shield for use as a UQ or TQ cover.

Here is my Fronkey inspired sock made of driducks. Not as breathable as I hoped with the sil end pieces. I havent had it out below freezing yet though.

Silly question....with a drawstring on each end holding it on the hammock, how do you get in/out? Seems like it would take me some acrobatics or at least some significant contortions to get in, pull the bag over the outside of my hammock then cinch up the cord at the other end. What am I missing? Do I need a zipper in the middle or an opening like a fronkey bugnet?

You're pretty much right on. This style is only usable on a hammock without a bugnet and preferably not so long that you are unable to easily reach the end of the hammock.

While it is totally doable, especially with the smaller hammock I've found I prefer, my next sock will be made with a SEEP for easier entry & exit. I'm even thinking of making it a double layer to see if an extra dead air space would prevent frost from forming on the layer against the hammock itself, but tell no one, its a secret.

The idea in my OP was to have the drawstrings in the middle of the hammock. One bag over the feet and one bag over the head cinching or tying together in the middle with a bit of overlap. With a loose ridgeline inside the sock, it would probably work alright.

If you're going to sew these things together, cinch one end to the footend of your hammock, then get into the hammock and slide into the sock like a sleeping bag. Bring it past your head and cinch the head end from the inside.

IMO, it's not worth sowing the frost bags because their material is so thin it will probably be a PITA to work with and fragile. I see these bags as mainly a solution for "I am broke and need to sleep in 10 degree nights, no sewing machine available" or "I just want to carry a light backup to add some warmth in an emergency." Despite being thin fabric, I have the feeling these bags will extend a sleeping system another 10-15 degrees or so. Combine with an emergency blanket and that's like 20-30 degrees of emergency buffer for just 4 or 5 oz.

Totally subscribing to this.

Subscribed. This is very intriguing. I hope someone tries this out and reports back Great research -way to think out of the box. I love stuff like this.

I did buy a couple of these to test out. I put together a grounded shelter and sleep system that weighs 1 lb 5 oz. One of these bags is used as a bivvy of sorts in this system. It was hot in a 50 degree environment.
