Def a big person lunch kit

elizabeth loveNovember 29, 2025✓ Verified purchase

This lunch kit is HUGE got this for my husband as he has long days going to work and straight to school getting home around 10pm. I’m able to fit his lunch and dinner in here along with snacks as he eats breakfast before leaving but you could def fit a small breakfast in here too. Theres def room for canned beverages in the top compartment as we use the bottom for the food. I use an ice pack and husband says it stays frozen until lunch and is def melted by lunch so I wouldn’t say this is the BEST insulation. Bc it’s so big it does seem bulky but is proportional for the person I got it for so keep that in mind. Read more

Great Quality, Just Not the Right Fit

Michelle KimSeptember 21, 2025✓ Verified purchase

This lunch bag is super spacious, well-insulated, and feels durable. It kept my food cold all day and was easy to clean with no lingering smell. In the end I returned it because the size didn’t work for my routine, but if you need a large, sturdy lunch tote this one’s a great pick. This would make a great gift. Read more

The Ultimate Lunch Combo: The MIER Insulated Lunch Bag and the KARRICO Leakproof XL Bento Box

David B BuieOctober 24, 2023✓ Verified purchase

When it comes to the perfect lunchtime duo for adults, the KARRICO Leakproof XL Bento Box and the MIER 2 Compartment 13 Liters Adult Lunch Box Insulated Lunch Bag make an unbeatable combination. I have been using these two products together for a while now, and I must say, I'm thoroughly impressed. The KARRICO Leakproof XL Bento Box is a game-changer. It's designed with convenience, durability, and functionality in mind. The two stacked bento boxes fit like a glove in the MIER 2 Compartment Insulated Lunch Bag, leaving the top compartment free for other essentials. This innovative pairing has transformed my daily lunch routine. MIER 2 Compartment 13 Liters Adult Lunch Box Insulated Lunch Bag Highlights: Impressive Insulation: The MIER lunch bag excels in keeping food at the desired temperature. I've enjoyed hot soups and chilled salads hours after packing. Two Compartments: The two compartments allow me to separate the bento box and other items like fruit, utensils, and beverages. It's incredibly spacious for an insulated lunch bag. Durability: The bag's construction feels solid, with robust zippers and reinforced stitching. It shows no signs of wear despite daily use. Convenient Carry: The shoulder strap and handles make it easy to transport. It's versatile, too, as it can be carried horizontally or vertically. KARRICO Leakproof XL Bento Box Highlights: Leakproof Assurance: I've had my fair share of lunchbox mishaps, but this bento box puts an end to that. It's truly leakproof. No more worrying about sauces or dressings escaping and creating a mess. Generous Capacity: The two-tier design provides ample space for a balanced meal. I can pack my main course and snacks without worrying about them getting squished or mixed up. Easy to Clean: Cleaning is a breeze, thanks to the removable compartments. I can toss them in the dishwasher, which saves me precious time. Sturdy Build: The KARRICO bento box is made from high-quality materials that withstand daily wear and tear. I haven't experienced any warping or issues with the latches. The combination of the KARRICO Leakproof XL Bento Box and the MIER 2 Compartment Insulated Lunch Bag has not only made my lunch routine more convenient but also more enjoyable. No more soggy sandwiches or tepid meals. The leakproof bento box keeps my food fresh and intact, while the insulated bag ensures it's at the right temperature when I'm ready to eat. If you're in search of a dependable and convenient lunchtime solution, I highly recommend this duo. It's the epitome of efficiency and quality, making it a worthy investment for anyone looking to elevate their lunch game. These products have certainly earned a permanent place in my daily routine.

Great quality, flawed design.

OscarDecember 29, 2025✓ Verified purchase

Lunch bag design is almost perfect. Love the color, the fabric and threading seems durable. I added photos to show how large it really is. You can also fit a pretty large stand up container in both compartments. The only thing I dislike, is the cup holders. They aren't built for holding cups. For holding other things, like a wallet or work badge, maybe a portable charger, it works (as long as you won't be swinging the bag around much). But if my fiance wants to keep bringing his own coffee and water to work, he will need to hold one in his hand and the other would take up more space in the lunch bag. This defeats the whole purpose of purchasing such a large bag to begin with. He takes public transportation so this really is disappointing, he needs all the space he can get and his hands free as much as possible. I cannot speak to the ice or heat retention yet, but it seems decent. This small defect with the cup holder compartments isn't enough for me to go through the hassle of returning the item, but I would definitely keep this in mind for any of you looking to purchase this bag to literally make life easier. For anyone who just needs something to take their lunch from the car to the break room, no biggie. But for those who work trades and/or take public transportation, keep searching. Read more
