I received this item fast from amazon, and I used it right away.
It fits a lot of items in it, thanks to its shape an wide opening. I can fit two to three small containers in it, a piece of fruit, bread, and even have room to put in hand sanitizer, gum, and napkins & utensils. If you take a sandwich, you will be able to fit that plus chips, fruit, a salad and all of your utensils and any extra snacks for throughout the day. It is stretchy and easy to stuff, however you do not want to put too many heavy things in it because the neoprene is thin.
I had a problem with my lunch bag as I noticed it had a small tear on the bottom after a week of using it! I think it either was caught on a rough surface, or one of my bags of chips created a tear in the fabric. I sewed it up right away, but I was mad that it tore so soon. I also noticed that it was starting to stretch on the bottom as well where it could tear in the future. Be careful of how you pack everything in the bag, because any corners sticking out will stretch the fabric and cause it to tear over time. The neoprene fabric could be thicker than it currently is. That is why i am giving it 3 stars instead of 5 because of this problem.
Other than the problem mentioned above, I absolutely love this lunch bag and I get compliments on it all the time from other people. It also will fold nicely to hide in your backpack, bag, or a shelf when it is empty. It fits what I usually take for lunch instead of taking my lunch in plastic grocery bags, which do get cumbersome and are not the most attractive to carry. I would recommend this to anyone who takes containers or a lot of snacks for throughout the day.
