## Description

Upgrade your shopping routine with this reusable insulated grocery bag designed to keep your food at the perfect temperature wherever you go. The large thermal compartment features high-efficiency insulation that helps maintain heat for warm meals and keeps frozen items cold during your grocery runs. The interior lining is fully leak proof, making it ideal for transporting ice, beverages, takeout containers or fresh produce without worrying about spills. Made with a durable 12 oz canvas exterior, this heavy duty cooler bag is built for daily use. It holds over 30 pounds of groceries and features a wide zippered top for easy loading. Two side pockets keep small items within reach, while the foldable design allows the bag to store flat when not in use. Whether you are carrying frozen items, warm dishes, picnic snacks or weekly groceries, the bag delivers reliable performance and long lasting insulation. Versatile and practical, this extra large insulated tote works as a grocery shopping bag, travel cooler, food delivery bag or picnic companion. It is designed to reduce the need for single use plastic bags while providing the strength and convenience that busy households require. A dependable reusable bag for shopping, outdoor trips, gatherings and everyday errands.

Review: I recommend this product - 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.
Review: Perfect for vacations when traveling by plane - 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.

### ⭐⭐⭐⭐⭐ Smaller than they used to be, but still amazing
*by A***R on November 26, 2025*

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 ...
