This bag is HUGE! When I first got it, I thought it was impracticable because of it's size, especially since I primarily shop for myself and buy groceries daily instead of weekly. I was completely wrong! In fact, I use this bag more than the mini version. I have had this bag for a couple months now, and it holds up great. Fits a great variety of items from frozen products to meats and produce. Everything holds very well during transportation (especially if the zipper is closed), even in the summer time. The handles are long and sturdy (can fit over your shoulder if it's a bit too heavy). I just would have liked to have a pocket on the outside for holding shopping lists, receipts and the like. Otherwise a great purchase!
They aren't kidding when they say it's generously sized! It feels quite sturdy, just watch out that it doesn't get too heavy for you to carry.
I've had this bag a couple of months now, and it's holding up well. The lining also makes it super easy to spot clean the inside. I haven't had to worry about cleaning the outside yet, the dark color still looks great.
It seems to do a nice job of keeping things cold, although it's been winter the whole time I've had it, so I haven't gotten to test in really warm weather!
It folds up easily for storage in the car.
I like this bag, and recommend it if you're looking for an insulated grocery bag.
