Does vacuum packing clothes (socks, hats, etc) ruin the insulation value?

[Tim K]

My experience is that some items stay smashed flat and lose insulation value. Specifically, I had some socks that got squashed pretty hard and never recovered. I had some poncho liners vac packed, and I cut them out of the bags for precisely this reason. I'd test the items before depending on them.

Been doing the vacuum trick for years to get more items in the A-B bag for deployments. Also helps because they never would leave a truck or pile of duffel bags out on the tarmac to get rained on right?

Or pack your duffel bags on the wrong pallet and tell you to go get your bags and put them on the other pallet because they don't have anyone to do it.
