place all of your totes under the cot to reduce air flow going under your cot, thus making it warmer. 👍

Wow that's awesome lol, i do pretty much the same thing but i have a fleece sleeping bag liner inside my surplus heavy canvas sleeping bag, and my u.s. wool blanket folded in half, then a camp quilt on very top. for outside sleeping in the open i have an insulated bivvy shell i can put on top or have it enclosed. So i can go in any layer or configuration easily. i can go from 50/60° well down below zero in boxers only. i really wanna try to get a M.S.S. and go camp in the ice 😁

Cool
