is there any insulation in them or just a reflective shell? insulation in the bottom- foam or something?
Thanks
To my knowledge the entire upper is their retain technology. Which by the way they claim is a derivative of space suits keeping astronauts warm in -460. The bottom is something more, rubber ish outside maybe some thin foam and then retain. They are waterproof and do breath.
I did do an experiment years ago... I put an extra wool sole liner in bottom, used military mauk wool bottie over my sock and pulled the attic shield over and sat in stand for couple hours in cold. Honestly it worked way better then my super duper expensive pack boots. Mine are sized to go over boots however and I would size down if going to do routinely.
Last weekend rifle in Montana, it was like 3 degrees snowing and blowing, we had a foot of snow. We found some fresh tracks near meadow and each set up for dusk. I put chamberlain, puffy pants and those over my insulated hiking boots and I was fine for an hour. If I were going to stand for more than an hour I would have thrown a toe warmer in each one and they create enough heat to extend what your body is no longer producing for a lingering stationary sit/stand.
