Interesting stuff, this insultex. I went to the tttrailgear site, and saw the underquilts and top quilts, but no temp ratings. Any idea what the ratings on this stuff would be?

Douglas,

Temp ratings vary a great deal for folks. It depends on construction method (ie: darting/pleating or not) shell material or not, end channels' design on undercquilts, etc.

On hammockforums.net, TeeDee was comfy @ 11F w/ 3layers and a ripstop inner & outer shell. Others have taken this to the 30's or 40's. 2 layers seem to be good for most to around 40ish.

I feel this insulation has far more potential. Since you hang, too, you need to check out the underquilts!!! Very light, and you can go without a shell if desired!

Mark Twight talks about the vest idea in his book and 40bellow makes a fleece vest w/ neoprene back - exactly the product some of you guys are taking about.
I have an old Golite windvest w/ silinylon back, great for very cold weather, but gets used only rarely.

Additional foam vest eperimenting on 05/13/2011 12:50:18 MDT Print View

I recently tried a stretchy nylon T shirt over my foam vest. It adds warmth because it greatly reduces the amount of heat lost (through convection) through the open design of the foam vest (around shoulders, arms, neck and sides). Here are some photos:

I continue to work with closed cell foam for clothing because I sweat heavily, wet out all my clothing and get cold.....even when others areound me are not cold. The closed cell foam retains its insulating value when wet.

I like this latest experiment with the foam vest and stretchy nylon T shirt combo. I wear a windbreaker or a raincoat over everything for additional reduction in air movement and heat loss.

The combo is a little hard to get on and off, however. Will look for improvements there. The foam doesn't slide against clothing very well.

Thanks Craig on 05/13/2011 22:30:16 MDT Print View

Craig,

Thanks for the link to similar posts from 3 years ago.

Nothing much new in my recent experiments.

I think there is some good potential here but none of us has really hit the bulls eye yet.

The potential of closed cell foam continues to interest me.

expanded polythene foam on 05/20/2011 08:38:19 MDT Print View

> Another option for "foam" clothes is insultex or PEF

I've been using this sort of stuff as insulation for about 25 years, since I first encountered it as anti-static packaging used in the electronics company I did my university industrial year with. Then, it was 'JiffyFoam' (as in JiffyBags). Laminate floor underlay is similar, but not as strong as the packaging versions.

I've used it as sit mat, sleep mat, tent groundsheet, cosy material, etc. It's great stuff, and the insulation is gives is remarkable for the thickness (not formmaly tested by me...). The only down side for a groundsheet is the bulk, but for car camping, it makes a nice, waterproof, cushioning, insulating, protecting layer that makes a tent more comfortable.

Much thinner versions are often used to protect electronics goods, such as plasma screens. So it's often available for free.

I did once think about emergency bivvy bags, but, again, the bulk is a bit of an issue, as is breathability (but I'd bet the latter is fixable).

Hi, cool vest, nice styling.

40 below used to make a foam-Back vest to prevent back sweat from soaking your down jacket under a backpack. There is just a pic on the front page now. They do sell some pretty comfortable foam. Also I have got nice foam from Oware. Both of them compress rather completely so dont make good footbeds. But jeez a hat of this stuff would fry your brain.

Also, there are nice light PFDs now, come in colors too.

On my sleeping-pad vest, an interesting avenue to pursue might be attach poncho sleeves to the edge, also giving a few inches of groundsheet on the sides, beyond the foam.

Dale,

I just noticed that you made an offer for me to use some of your blue 5mm EVA. Sorry I didn't respond earlier but I overlooked that part of your post.

Anyhow, I have a lot of foam to experiment with and am more short of ideas and skills than foam so I'll pass.

Thanks for the offer, however.

Kevin,

I fooled around with insultex but didn't think it worked very well for my needs. Here's a link. If you'll scroll down you will see my experience with it.

Paul,

I got an e-mail back from 40 below in response to my request for more info on the foam vest. Vest weighs 18 ounces and has foam on the back only. Looks like they are aiming at the cold weather market. Still not quite what I'm looking for but heading in the right direction.

When you are done with your activity, you can take off the vestand freeze-dry the perspiration off the inside back. Moisture that will bein your base layer is much easier to dry than to try and get it out of athick fleece or insulated jacket.
