JTX Insulated Lunch Bag Thermal Lunch Tote Bag Large Cooler Tote Bag for Adult and Kids with Adjustable Shoulder Strap Double Deck Cooler for School/Office/Picnic/Travel/Camping

This lunch box bag is of good quality and has a large capacity. Besides, there are two floors. Both layers are insulated so the food stays fresh all the time.

This lunch bag is of a size that is just perfect for carrying enough foods for a good meal. The strap is adjustable and can be made to carrying by hand or on shoulder. It has two compartments, a lower part for storing heavier materials and a larger upper part on top for carrying things that are bulkier, but lighter in weight. It also has a thin front pouch for something like sliced cheese or ham. I have been taking it with me to school and it has served me very well.I placed a glass container of water at 64 °C (147 °F) in the lower compartment and zipped it. The room temperature was at 21 °C (70 °F). After two hours, the water stayed at around 35 °C (95 °F). Had the initial temperature been higher, the end temperature would have been greater, too.

So I though it was a little bigger than what it is, but it's about an average size in comparison to others. The material and insulation are what really make this special though because it's so lightweight and keeps my hot melt roast beef warm for four and half hours til lunch every day. Not a product you can ever go wrong with and the colors are just icing on the cake!

The bag is OK however it comes with a strap I plan on using. However, when I try to attach the strap the part that snaps in to the bag does not attach because it’s too small. It’s clearly the wrong piece that they sent. It’s a pain because it was expensive and now I have to send back. I’d prefer if they just sent me a strap attachment that actually work.
