Question: Sorry I don't understand what does the cooler mean. I want to find a lunch box to keep my lunch hot instead of cold, Can it work to keep warm?
Document: I have had this lunch box for less than a month and the zipper is already junk on it, my food doesnt stay cold unless i have 5 or 6 refreezable bags of ice in it and its not as big as it says it is. AVOID
Be aware that the bottom is not reinforced, so that if you place anything of any weight - like a pint or larger bottle of water - in the cooler, it will sag significantly. I like the shape, so I will work on creating a hard plastic bottom for it. That should distribute the load to the perimeter of the bottom.
different shape than regular lunch boxes, making it look uniqe (looks like dachshund (sausage) dogs, short and long!). I love my lunch box. quality is great being theromos.
My husband takes lunch to work every day - yes, I pack it for him. I've spent a lot of money in the last few years on cheap can coolers and etc, trying to get the right blend of space and shape for his very particular (and rigid) lunch needs. This lunch lugger does it for me. It holds two sandwich sized Lunch Bots boxes (or one Lunch Bots and one pint canning jar depending on whether it's a sandwich day or a soup day!
Have used this cooler on the back of my cruiser bike and it keeps things nice and cold.holds quite a bit of drinks. The downside is, if you tilt it to the side it will leak. All in all, it is a descent product.
This is a really great cooler. It is BIG, though! Not something I would use as a lunch cooler. It fits a complete 12 pack of cans plus ice. Seems pretty water tight and kept things very cool during a round of golf. Highly recommend although maybe not for its marketed use!
I really wanted to love this cooler. I really did. It was perfect. It fit right perfectly on my bike rack. It had plenty of room. But the one zipper was broke when I got it. I thought, &#34;Ok, fluke.&#34; The second zipper failed me two months later. I never held it by the handle. I always used the shoulder strap. The heaviest thing I ever put in it was my lunch + a 16oz can.
I use this bag almost every day to bring my meals to work. It's large enough to contain a salad bar container along with food items for breakfast and a snack. Keeps the items cool (when I put in ice packs) and easy to wipe & clean. Love it!
Ordered this for my son to take his lunch to school (7th grade). Item was much larger than we assumed in the picture, way too big for him to take to school. Would be something you would take on a fishing trip with multiple people. The item didn't come in it's own box, and the zipper tag was frayed and missing half of it (assuming from how it was stored).
This bag is great, but it really is very large. It will be perfect for my son to bring to school to store a variety of snacks and lunch with plenty of room for ice packs. The front zipper bag is long enough to hold his Thermos Funtainer 16 oz drink bottle! My son is picky and needs a big bag, but most would find it really big for lunch.
Answer: It's a well insulated lunch bag. I got it for my husband but it's fairly large. He has a hard time making it full even with a big ice pack in it. It can easily work to pack lunch for two people. The less it is packed, the harder time it has keeping stuff cold. I'd imagine that it would be fine for keeping stuff warm as well because it's just well insulated, it doesn't have a built in cold element in it. however we have thermos food containers and they are really amazing for keeping food hot. It will keep food scorching hot for hours and hours.
