Insulation between hammock and underquilt

[Dmac]

So, I am pretty new to the hammock thing. I have read that a windproof layer between the underquilt and the hammock will help keep you warm. I have also read that a space blanket will help by reflecting back radiated body heat. So what if I found something that did both.

Diamond Living LLC makes a hardwood floor underlayment material that is a layer of space blanket material (mylar I think) attached to a thin layer of neoprene.

Would this work? It would be a cheap and light insulation solution. You can get a 50'x4' roll for $49.00 or about $6.25 for a 4'x 6'4" piece. It is very light and would be fairly tough. What do you guys think?

If it is very flexible, and cut to the right dimensions, it should work. But what is the weight? A $3, 2 or 3 oz space blanket is already wind and water proof, though it adds no insulation other than as a radiant blocker. So are ccf pads, more or less.

Good questions. It's essentially the same material that scuba suits are made of (only thinner) so it's definitely flexible. It's only 2 mm thick so it is actually very light--no more than a couple of ounces. It would be lighter and more compact that the CCF pad. The value I see with the neoprene is that it would be easier to position and to keep from slipping around and balling up.

what I will do in colder times is to use a construction grade trash bag (ie a BF plastic bag) as a pack liner and as the wind blocker between the UQ and the hammock in the torso area - I have a smallish sit pad I use for my feet so I don't need the wind blocker all the way down to my feet

wrt radiant heat reflection - I don't think this is of much value when the reflector is in direct contact with the hammock fabric and the only gains are in the blocking of the wind

What do you guys think?

I think that if you buy a roll, I'll buy some from you.

I just might too..

What do you attribute the very noticeable and instant warmth boost many of us notice when adding a space blanket to a HHSS? Just vapor barrier effect? ( might be )

I'll take you up on that if you're really interested and if there are a few others. I don't mind spending money, but there is no way I'll ever use 50' of the stuff

Neoprene is comparatively heavy stuff, but only 2mm might be light enough. It might work better as a pad, since it might not drape well, but we'll see...

I've had success laying an unsultex layer in my UQ, it's $7/yd and weighs almost nothing for a piece that's 36"x60, it's less than 2 oz...

Let us know how it works out!
