Review on Large Capacity Insulated Lunch Bag by MOKALOO - Removable Shoulder Strap, Multi-functional Reusable Thermal Cooler for Men and Women by Diane Glaser

I use it as a combination bag and lunch bag. I haven't tested the hot/cold air function described, but it certainly holds quite a bit of food. The outer zip pockets hold little, even when the inner compartment is full. The outer mesh pockets can hold my 24 ounce thermal underwear bottle, but for added security I slip a shoulder strap through my bottle handle. It wasn't lacking in durability or toughness, and the interior cleans up nicely. I definitely recommend this lunch bag. My only complaint, if you can call it that, is that I wished for better/more colors.
