Awesome quality!!!

As a service plumber I needed a good lunch bag that would keep hot, hot, and cold, cold, but also have plenty of room for extra snacks and drinks for those extra long shifts and over night shifts. this bag does the trick I only put to pictures on here because there are so many pics and videos on here. I love this lunch bag. The material feels solid, zippers are great, definitely plenty of storage, and I love that it had the big open section for cold food and drinks and then it has the expandable top section that will keep your hot food nice and hot. You can tell that the top section is for hot food because of the material on the inside. The shiny foil like insulation is perfect for keeping stuff hot. But it will keep cold also if you have cold items and an ice pack. I give this Maelstrom lunch bag a solid 10/10 and 5 out of 5 stars! If you need a great bag for work this is it.

Well made lunchbag

Just received the lunchbag. So far so good. Using it for first time today. It has a lot of room and many useful pockets. The tension on side water bottle pocket is tight and makes it hard to keep the bag opened all the way up but I am sure it will loosen and fill out the form as I use it over time. It is a well made lunch bag. I am happy with my purchase.

Sturdy, Good Size

It's a sturdy, well-insulated bag with a good two-piece handle with a Velcro closure and a decent shoulder strap. Size-wise, this is the right size to take some necessaries along for my daughter on a quick trip out of town where we need to carry some milk or berries, or even for beverages for a short trip to the beach. It feels like it should hold up very well, and I don't doubt that it's waterproof. There are several pockets on the outside for miscellany -- which I tend not to use, but would be handy if you need it.The expanding feature enlarges a pocket in the top flap, not the main body of the cooler. It takes that flap from large enough for, say, some infant food pouches, to deep enough for a small Tupperware container of apple slices. The main pocket is plenty tall enough for beer bottles, but it won't fit a bottle of wine (unless you kind of wedge it in on the diagonal, in which case it works). If you take large lunches to work or school, this would be perfect.Overall, it's a handy bag cooler, and I expect that we will be happily using it for years.

Great lunchbox

Actually, a very nice size. The material works well. The repels dirt and dust have been using it for about three months keeps things cool plenty of room.
