Still love it

SpaceJune 30, 2025✓ Verified purchase

This thing keeps it cool. Literally. I don't think I've ever had a better lunch bag than this one (granted I only ever owned like 2 others before this one but stay with me.) First, this thing is huge and yet somehow compact. There's a storage compartment on the top perfect for holding silverware, floss, napkins or smaller Tupperware. Two "cup" holders on each side that could each hold a fairly large drink. Then there's a pouch on the front. To be honest I have no idea what to put there because the top one already holds so much. Now the actual cooler part, huge. You'd think I'm feeding a family with how much I can fit in there when really it's all just for me, myself and I, and we love this cooler. I left a Costco bag of shrimp and potstickers in that bag overnight in the warm mudroom, from around 7pm-6am and when I woke up to the horror of realizing what I had done I fully expected rancid food, but no, everything was still frozen. Great quality, zippers open and close with ease, the inside is easy to clean AND water proof. I literally used this thing as a cooler for a trip, ice and everything, none of the water leaked out the bottom. Worth every penny, will absolutely get another one once my current one gets worn out.

Spacious, Durable Lunch Cooler Great for Work or Road Trips

RiverDecember 8, 2025✓ Verified purchase

The GLENKEY lunch box strikes a good balance between size, durability, and convenience. It’s large enough to hold a full day’s worth of meals and drinks, yet not so bulky that it becomes cumbersome. The insulated compartment and leak-proof liner give confidence that wet items or melted ice won’t seep out. The dual compartments and external pockets help keep food and non-food items separated. While it may not keep ice frozen all day under extreme heat, for standard workdays or travel it performs reliably. It’s a practical choice if you want one bag to handle heavy daily use without constant maintenance. Read more

Great lunch box for anything

Brooke SandersJune 5, 2025✓ Verified purchase

I got this for my husband for work and it worked great but I ended up stealing it for my toddlers snacks. It holds so much and the extended top pouch was perfect for putting diapers and wipes in. I use it all the time for parks, or just going out side with the kids it keeps their waters cold and I can have snacks and wipes ready for them while they are outside playing. It’s very durable and holds alot. Read more

Great quality!

Kyrsten WorleyFebruary 23, 2026✓ Verified purchase

Originally bought this to pack my finance lunches. However I ended up using it more for when I would go out and about with my son! Can easily pack 2-3 lunches in there. Great for picnics and day trips. Food and drinks stay cold, and love the extra compartment on the top for non cold food. Read more

Large and Love

JennaFebruary 1, 2026✓ Verified purchase

This bag has lasted me over a year, and I am still using it. I could fit a whole picnic for two if I wanted. It is perfect for a "Girl Lunch" when you can't decide what you want to eat that day. While it is big and bulky, the different strap options make it easier to hold or put over your shoulder. Very easy to use, user-friendly. Read more

Good size

Carlos A.January 27, 2026✓ Verified purchase

Great lunch bag, fits everything I need for the full day at work. We also use it for travel in the car as a cooler, keeps items cold with the use of an ice pack. Read more

Great lunch bag, great price!

Damion WaltersdDecember 1, 2025✓ Verified purchase

--Surprisingly high quality from a materials standpoint given the price point. --I love the little details such as the ability to expand the top compartment via zipper OR compress the main compartment using the same zipper. --It has a very clean minimalistic aesthetic. --Volume wise it packs quite a bit. In the main compartment I am able to fit 4 Stojo circular tupperware + an overnight oats container. --The carry handle is comfortable and they added a nice touch allowing you to velcro the straps if you prefer. Overall a great product, again especially for the price. Highly recommend! Read more
