Eagle, your right I didn’t mean to be confusing, I’ve been sewing Multicam for too long. 7624U is correct it is a liner we built for a challenge about ten years ago. The challenge was a liner for extreme cold conditions with an eye to save weight for Denali accents and ops above the Arctic Circle. Basically the image is that liner which is the top piece in a modular system.

In this liners early stages our children would try it and unanimously describe its warmth as lava, we had denoted it having the BTR membrane with orange until soldiers wouldn’t have it anymore. I have always thought about the lava analogy and had this in mind for a while and now Multicam Black and Tropic have become available.

This is in the wrap configuration which is still large enough for a medium pack underneath, it can be used/attached to our shells, and in several other ways. The BTR was part of a NASA project and reflects warmth back but allows vapor to move out and away For great comfort. 7624U is right these are expensive most of those cost are quality materials and quantities.

This version isn’t on the site just now it is more for our Outdoor Retailers but we’re building them.

Images are a bit of an analogy indicating the infrared energy of inner heat reflected and retained by a crust...
