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.

Perfect lunch bag for the active teen- can carry so much more than lunch!

rlpDecember 27, 2025✓ Verified purchase

My daughter uses this every day for her school lunch. I love the multiple compartments. I put the ice pack and drink in the bottom compartment- it fits one large thermos, but can probably fit a few soda cans or water bottles. Her sandwich and snack go in the top so they don't get squished, and there's even a zipper pouch inside the top portion, which is great for medication, notes, etc. We use a carabiner to hang it from her backpack, but the straps are easy to use, too.

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

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

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
