I’m using it in my camper because of the tight quarters of making the bed with fitted sheets. Bought a sheet liner for it and in my world it works out great. Had one hot night in it but the optional zippers made a quick fix of it. Too had a cold night and those zippers again made an instant difference as well. Great design in my mind.

Just received as a gift for my son, but the bag is completely missing feature #3, the foot escape, as seen in the video on the product's page.
Generally I like the bag and I'm willing to pay more to support US companies, but if all the pictures show the foot escape and the video spends that much time on it, it should be there or I feel scammed. Thats the reason for 3 stars.

This was my second bunker bag purchase as a Father’s Day gift. My first experience with the bunker bag was our annual rifle elk hunt in the San Juan’s, temps were approaching zero but I was always warm, cozy, and comfortable. The dominator simply isn’t complete without it and that’s why I had to grab one for my dad. My only wish is one day in the future we get a 2 person version of the bag so I can get the wife involved.
