Great lunch box, very versatile!

I. D. SoriaMay 27, 2019✓ Verified purchase

I’m loving my lunch bag! Works great because you can put it on the handle of a rolling backpack or luggage just like other luggage bags. Which is super helpful for commuting to work. You can hook on the pull bars from either the flat top of the bag which makes it really neat and tidy or the from the short side of the bag which has a buckle which makes it easy to detach/attach without having to slide it on from the top. The zip pocket on the outside and mesh pocket on the inside are very handy for storing napkins, plastic ware, condiments etc., and for storing the shoulder strap, which also comes in handy to carry by itself on crowded commuter trains and busses. It’s made of good sturdy nylon that matched my rolling backpack and sits nicely on stop. One other great thing about this is the expand ability. It’s got a zipper all the way around that basically allows you to double the size of the bag. This is awesome because if you just have a sandwich and chips and canned beverage or just a Tupperware type container of food you can keep it slim and small. But if you have a lot more, say breakfast and lunch and/or snacks or just anything that takes up a lot of room you can unzip the bag and it doubles the size basically making it like a good sized square box lunch instead of a rectangular slim lunch bag. Then the handle on top is perfect for carrying like a traditional cube shaped lunch box. You can fit a lot of stuff in it that way and still hang it on your backpack/luggage. And the two handles allow you to keep your food upright incase you’re worried about liquids leaking from your containers. You just use the one that’ll keep it upright. The only ding I might give this is they might want to make these with a plastic liner that is just slightly thicker. The soft plastic liner they have in this is great and your standard plastic liner that most other bags have, but when I put a super hot Tupperware type container straight from the microwave, I thought the plastic was almost going to melt. It did seem like it got too soft and I think did melt a wrinkle into it. I have an Igloo tote that I’ve put hot clean containers into also and they get soft to but never ever melt. Granted it was SUPER hot but still they should probably go a couple mils thicker on the lining. But other than that the lining works fine. Note: At my work if you heat up food in the company kitchen, you have to move it to the eating area to eat, so you basically have to put hot containers back in to move to the dining area. Also, it would be neat if they made the side buckle handle with some way to lengthen/shorten it like a should strap does. But over all this is a great lunch box. I’m loving it! Highly recommend!!

I haven't used it yet but it seems to be a quality product and the size I was looking for. I have checked the inside dims to see if my existing container will fit and voila it does, with plenty of room for other things. I would recommend your product to other people. Thank you. Read more

Some details missing but not a deal breaker

R. LopezJanuary 23, 2026✓ Verified purchase

Good bit room for improvement . I bought this to replace my Titan lunch bag. This comes n a variety of colors. Zipper and fabric appear to be of good quality. My only complaint or suggestion would be to add a seperate compartment for the ice packs. This did not come with gel packs. The size is about the same as Titan. Hopefully it last just as long.

Sturdy and versatile

Kevin B AbelJanuary 25, 2026✓ Verified purchase

I can pack a flat container with a sandwich, apple, and yogurt one day, and then expand it to fit my big lunch salad bowl the next. Easy to adjust. The cup holder is handy and the adjustable straps helped me carry it cross body when I was on crutches. Versatile, easy to clean on the inside, and sturdy. Small, thin, reusable ice packs are needed to keep your food cold, but with the ice packs, the bag keeps food cool for around 6 hours. Read more

Two ways to carry makes this a must have!

TFDecember 31, 2025✓ Verified purchase

This is a versatile lunch box that can be carried two different ways. It is roomy and we have not had any problem fitting a variety of meal prep containers in the lunch box. With an ice pack, it keeps food cool enough through the morning to lunch time. The mesh pocket on the side is an added extra that comes in handy. Shopped for just the right lunch box and this one is it. Read more

Nice size for lunch and good insulation for what it is.

just meJune 1, 2025✓ Verified purchase

Take a lunch to work daily--purchased this one to replace one that I left somewhere on campus. I like the size of this and the ability to expand the depth if needed. The ice pack I use is typically still partially frozen when I get home, so I am satisfied with the ability to keep stuff cool, even somedays when I am doing field work and packing this around in a hot car till lunchtime. Zipper is smooth and I have had zero problems with it; the entire item is well constructed, and easy to clean the outside if needed. Would purchase again. Read more
