Nice and roomy lunch box!
Color: A. Black
Love this lunch box! Roomy but still pretty light. Love all of the pockets! Nicely insulated and keeps things cold. It is a soft flexible material and keeps its shape. Seems to be durable. The only issue is sometimes the zipper gets caught on the corners at the top, but as long as you pay attention it shouldn't be an issue. Odor free. Easy to clean. Oh and it comes in many colors! I also have the light purple version and love it just as much! So this is the second one I bought because my husband was jealous of mine. Would highly recommend! ... show more

Sturdy, spacious, and light. Perfect
Color: A. Black
Love it! It’s spacious, sturdy, and light. I’m a huge gym girl so I really needed something to hold ALL of my meal prep for my long days. It holds more than I thought and conveniently has a section for cooling packs. It might be bulky for some people but it 100% does it for me. Already recommended it to my bodybuilding friends ... show more

Top Heavy
Color: A. Black
I bought this particular lunch bag for size and pockets. I work 10 hour shifts as a telehealth nurse and wanted something that could also function to carry additional small items so as not to carry a purse or additional bag. I eat my main meal at work and take snacks to cover either breakfast or dinner depending on my shift. The main compartment fits all my meal prep containers plus ice packs. The food stays cold for my entire shift. There are some tiny nuances to this lunch bag. The main lid to the bag is top heavy and that’s without anything in it. The snap that holds the 2 carry handles is small and awkward. Hence, I don’t use the snap. I would like it better with either a bigger piece of material with the snap or Velcro. The “bottle net” on the side is flimsy. I use a 24 oz refillable water bottle and it feels like it’s going to either slip out of the pocket or break it. So I end up carrying that separately. Overall I am happy with my purchase. I bought it for the convenience of carrying my food containers, keeping my food cold my entire shift, plus eliminating any additional bags/purse and it does all of that. ... show more

Perfect for a full day of meals (3-5 containers)
Color: A. Black
I use this lunch box for both school and work, and it’s been perfect for my needs. I’m a very active person and eat multiple meals throughout the day, and this bag fits 4–5 meals easily. For reference, I use containers that are about 8 in (L) × 5 in (W) × 2.5 in (H), and I can still fit my water bottle inside. The expandable top compartment is also great for snacks. The interior is easy to clean. I usually just wipe it down with a damp cloth, a little soap, and dry it off, or use a paper towel with some alcohol. It doesn’t hold onto food smells, which is a huge plus. It keeps my food warm for a good amount of time, and so far it’s been very sturdy. The handle feels durable and has a button that lets you secure the two straps together, which makes carrying it more comfortable. I also like the design, it’s simple and clean, without big logos or anything flashy. Overall, I’m really happy with this purchase. ... show more

It’s nice a lunch box and has plenty of room for long days.
Color: A. Black
Love it. I use ice packs not ice cubes. Plenty of space. I put many essentials in this for the day of driving. I’ve only had it for a little over a month, but I give it no quarter, and it’s held up well. My only complaint is the shoulder strap is thin-ish, but it works fine.
