I do have one...but....It's got a banks logo on the side. The fabric is super heavy canvas, with a super tough strap & handle and leather accents on the bottom corners. I purchased it @ a thrift store....had it at least 10 years. It's awesome. It looks like This LL Bean one. Click to view

Thanks, nicole - I would definitely trust the construction of a bag from LLBean.

My Trader Joe's zipper, black with red trim insulated inside, canvass exterior is perfect. Very flat when not in use, hold a ton, and keeps things cool for a good hour - two when we are running errands.

It may be overkill for what you're looking for anyway, but I bought a really nice Yeti cooler bag from Homegoods a few years ago because it was a great price (for them because they are so $$$) but I took it back. It had this weird shaped opening that prevented anything of any size from fitting through it. Just a warning, should you be tempted. I'll post a pic of the one I tried. I have a nice one that I got at costco, but it's not square so it, too limits the size of things that can fit through the openings. I have a bag I really like, but I can't recall where I got it.

Don't buy this if you ever want to put a baking dish or casserole dish in it. Works fine for loose drink cans but $$$ .

The one I like has a zipper top like this where the whole top opens up out of the way. Makes it easy to put pans and containers in and out.

I used the Trader Joe's version for a few years until one trip with the handle ripped so I can't recommend it. Now, I use a hard sided cooler.

Thanks for the Yeti experience - I wondered about it.

My Costco bag is going strong after about 10 years, but I don't use it every week.

I have a variety of insulated bags, I use for different things.

For big shopping, I use a bag I bought at Sam's Club at least 10 years ago and pack it full. When I visit Sam's or Costco, I often purchase more than what fits in it, so picked up a different bag at a thrift store. I use that one for vegetables and other "cool" things, while the Sam's bag is for milk products and things that need to stay frozen.

I also have a couple of VERY cheap, small bags, that I might use for ice cream. Just the right size, and I pack the ice cream in it, then pack THAT bag into one of the bigger bags. Ice cream is still frozen, altho just starting to go soft, after a 90 minute trip.

I also use those small cheap bags for the Sam's or Costco chickens to keep the heat in and protect the car from drips.

My husband brought our bag to me.... out of the car...we use it every week....the brand tag: Picnic at Ascot. Did a search....found it! It has a video too....click

This may be more than you wanted but we have two of these. One is similar to the one in this LINK. It plugs into any 12 volt system in your car or truck (most have this outlet now). I scanned the A-zon website and they have several in other sizes. i’d probably get the largest I could handle for groceries.

The other is a larger Coleman that we use for longer car trips. We’ve had it for several years and love it. I think DH bought it at Cabelas or a similar store. We can buy items for lunch, snacks, drinks, etc and then just put it on a trolley and plug it when we get to our hotel room. Both have AC adapters sold separately for that purpose.

I have 2 cooler bags from Aldi and I love them! They were like $7.99 each a couple of years ago.

I also really like the TJ one that Kendrah mentioned. Love that it is flat and fits behind my car seat. I typically only use it in the summer when I need to stop for a few cold things at the grocery store before I continue with the rest of my errands. I have had cold items in there in a hot car for several hours with no problems.
