Great grocery bag!
I love this bag! I have been on the search for a sturdy reusable and insulated bag, and this fits the bill. I love that the strap are sewn all the way around- I was so tired of straps ripping off all the cheaper versions. It’s big enough without being too big. The dark blue is a lovely color.

High Quality, good zipper
I love it! Old reusuable bags were ripped to shreds. Had a hard time finding another good size thermal bag, for me. Most are too big to lift once perishables are inside. This one is perfect for a shorter person to carry on shoulder, with a hand supporting the weight underneath. Straps are perfect, the jute fabric is very posh. It came in a pretty, heavyweight, plastic bag with zipper, for protection. Beautiful. Used the first time yesterday- it held two bags of ice, plus a regular paper bag 3/4 full of groceries. My only issue was putting it in a dirty shopping cart!

Great grocery bag!
Great durable & functional grocery bag! Summers are brutal in my area so anything that helps keep meats cool during grocery trips is helpful. Fits the large “family” size trays that hold meat perfectly, no side tilt like regular grocery bags. The insulated interior is also a breeze to clean. Will be purchasing additional bags.

Heavy duty insulated bag
It’s just a little too large. When I fill it with grocery items, it’s almost too heavy to carry. But it’s very well insulated and heavy duty.

size is misleading
Bag seems really nice, but photos are very misleading in terms of size. The bag appeared much larger in the photos, and I doubt it would hold 40 cans as claimed (24 pack of soda fit with a little bit of room to spare). overall, for almost $30 i expected a bag that matched the photos/expectations for size. for reference this is the x-large size.

A Must for Summer Grocery Shopping…
If you’re like me, then grocery is a three-store project of hopping from Costco to a discount grocery store, to a regular grocery store to get all the stuff I didn’t get at the first two stores. In the summer heat this can be problematic because let’s face it, the trunk of a car gets very hot. So I bought two of these bags keep all my cold stuff cold while I’m out and about store hopping. So far, the results have been great… no need for ice packs.The X-Large bag is very big and can handle big bulky Costco meat purchases and all my other cold stuff as well. Although you can overload these bags with a lot of weighty items, I wouldn’t go crazy. The bags seem sturdy enough but because of their size, but it would be very easy to overload them and make them too heavy to carry.The bags would also be helpful when bringing hot or cold food to a gathering. The X-Large size is long and wide enough to fit a 9×13 pans inside of it, but it’s very deep. So if you have a couple of pans to pack you’ll need to figure out something so you can stack more than one on top of one another.All in all for shopping, they’re great.

I got the smaller size and love it. Big enough for a family of 4 with snacks and meals and ice packs. Will be getting the larger bag for picnics and long days out, but having two is ideal. Itâs well constructed and very pretty. Does not look or feel cheap.
