Nook Theory Reusable Insulated Grocery Bag - Leak Proof, X Large Cooler Bag

Lovely colors, tidy square fit in my trunk when filled and fold down nicely to store in the vehicle. No problems with leakage, mild temperature control. If you need serious cooling or insulation I would invest in a sturdier bag, but these are perfect for grocery runs as I typically use them. Decent durability and good value for what I paid.

So far so good. It hasn’t leaked, has kept things cold from 7-5 at the pool, and packed nicely without using too much weight. We are going to take it with us shopping today which will be its second use. The side pockets securely held our Yeti coffee cups. I love the color. The straps could be a little longer to go over my husband’s shoulder and it’s hard to zip. The reason it’s hard to zip is because it’s soft edges but it has to be because if they made it more structured it wouldn’t pack as flat and would be heavier. I bought it for traveling so having to hold up the top to zip with two hands is not a big deal. Also you can zip from either side- having two zippers help. The zippers and zipper function are smooth. It seems really well stitched to me but the straps aren’t thick or reinforced. Again this helps with packing and weight so that’s probably the best you can hope for though maybe an added Velcro padded wrap around to combine the two handles would help. I bought this one over another because the straps aren’t thick sewn on all the way from the bottom as opposed to just at the top which distributes weight better and will help prevent ripping. I gave it five stars because the price for what you get is a bargain.

I bought 2 of these XL bags in August 2024 and I love them so much I just bought 2 more. The ones from 2024 are going strong- zipper zips, sides hold up, straps are still strappy- in fact I forgot when I bought them and thought I'd only had them for a few months-- more like over 2 years. The new bags are a few inches narrower and shorter than the ones from a year ago. Not a deal breaker for me, but the old size was amazing. I've attached a photo- the caramel bag is from 2024 and it's been used and loved for over a year so it's a bit slumpy- the new bag (blue) is ever so slightly smaller. But still nice. I'm not sure which size I prefer yet- the larger one fit a LOT of groceries, but it could get a little heavy so I might like the smaller one better. Anyway- it keeps items cold and ice cream frozen enough that I'm not worried if I have to stop on the way home. I've left ice cream in my car for 40 min on an 80 degree day and it was fine when I got home- The bag was full at the time- not sure how well it would do by itself (one pint). Overall, I love these bags- I needed 2 more because I bring people food and they keep disappearing for a week or 2 ...

I can't imagine how anyone could rate these amazing bags with less than five stars. I've purchased nearly twenty-five of the XLs and store four of these vertically inside a fifth. I've equipped each bag with two caribeaner clips so they easily attach to the outside of a shopping cart just beneath the handle. I have so many because I use these for more than transferring groceries and not a single one has failed me to date and besides, I also always get compliments at the store because everyone everywhere appreciates these fantastic bags. Now, most zippers in general don't travel well around corners. However, these bags are so exceptionally well made and sturdy that every single one zips up easily for me everytime. After years of buying cloth bags with handles and reusing plastic bags that eventually tear. These bags are an absolute game changer. Sometimes I leave my Ice blocks inside them and two days later they're still frozen. I give them a 100% because they do what they're supposed to.

I bought this as a delivery bag for doordash, it works great for medium size orders. it also works great on small shopping orders. It is extremely well built and high quality cloth. it is well insulated and when I buy frozen seafood for my personal use I use this bag to store it in, it keeps it cold on the 45-minute drive home. When I do the Wingstop orders I zip up the bag and it keeps the odor in as well as keeping it very warm on long delivery drives. The only gripe I have about it is that the zipper fobs have no eyelet in them for lanyards. they're big solid hunks of metal and extremely durable though so there's little chance they're going to break like so many cheaper zipper fobs have. I did have to add a cut to fit piece of cardboard in the base for reinforcement, The bottom is very soft and things will flop around if you don't.

My old insulated bag by another brand was wearing out so I bought this bag. I chose it because the straps looked sturdy and the bag appeared well made. I have used it several weeks to carry my empty glass bottles to the store, and then to carry two full glass bottles, 1/2 gallon each, from the store to my car and then to my home. The bag has done well. I am glad that I bought it.

Great bag/ no shoulder strap/ even though add states there is one-

This is my 4th bag! They are the best I have ever used for keeping my frozen items frozen! Folds up nicely after use. Easy to wipe the inside if it gets sticky. Holds a lot of frozen goodies. Very durable. My first 2 bags I have had for a few years. No signs of wear. I just need more!

Perfect, bought it for our Japan trip to bring back Royce Chocolates, kept them cool for a 14hr flight, super lightweight and the exterior pockets were handy to hold passport and phone. Packed easily flat, and holds shape well.

So far this cooler bag has been amazing. Perfect size for groceries. Tall and wide enough for a variety of different products. Great for taking to parties cause it can fit a case of pop or beer plus extras like snacks etc. Keeps things cold but I haven’t used it for heated things yet but I’m sure it’d work great. Can’t say in the durability yet as I haven’t used it very long but so far no issues and I’ve filled it will heavy things.

I always get compliments on this bag at grocery store. I have two now.

Love it, well-made. Hope it will last for carrying hot food to church's lunches.

Super quality product - use in the car for catering events. No external food smells in the car, safe and secure.
