5.0 out of 5 stars Super cute and durable Perfect for my daughters school lunchVariation: Color: Rose Quartz
5.0 out of 5 stars Excellent I love this product, mostly because it sits flat and not vertical like most lunch bags. It has two spacious compartments. The only thing I was surprised about was that it did not come with a shoulder strap. I found a real cute one through Amazon so it all worked out.Variation: Color: Cream

5.0 out of 5 stars Stylish and Functional Lunchbox I pack my husband a lunch everyday for work, and he normally just takes it in a reusable bag. I decided I wanted to upgrade his lunchbox, so when I came across this Stanley FlowState Duo lunchbox, I had to get it! I purchased the black, as I thought it was more masculine for my husband, I actually ended up loving the sleek black color as well. It has a carry handle on top which is sturdy, but it also comes with two hook loops where you could attach a longer should strap to if you have a longer commute to work. The outside zipper is smooth opening and closing, gliding with ease. Inside there is a mesh zippered picked at the top. It is meant to hold the Stanley FlowState Spring water bottle. I found that it is the perfect spot to keep silverware or any foods that you don’t want smushed in the main compartment. The lunchbox itself is a good size, 7.76L. It is large enough to hold my Ello glass 3.4cup containers which are my go to for lunches. I found that the lunchbox holds the temperature of the items inside pretty well, even it being left in the car for a few hours, the food inside retained its cool temperature. I also like to add an ice pack sometimes to keep it extra cold, which is where the waterproof liner comes in handy. It is easy to wipe up spills and keep extra moisture contained. I am very impressed with the quality of this lunchbox from the sleek black color, to the large size for an adult lunch, to the waterproof lining and extra mesh zippered storage in the top. I think the price is on par with other name brand lunchboxes. I am very pleased with my purchase and excited to continue packing lunches in it.Variation: Color: Black
5.0 out of 5 stars An all around excellent lunch box with the quality you'd expect from Stanley. This is an awesome lunch box. The interior is spacious and the construction quality is solid. I love the water resistant lining too. I recently put a water bottle in it and made my way to work to find out the bottle was slightly open and there was water about a half inch deep when I opened it. I dumped it, wiped it down and it was like it never happened. The color is a lovely ivory which is somewhat susceptible to smudges but not anywhere near as much as I thought. The domed top is super useful since you can fit additional things in it. The only thing is change is I’d include a shoulder strap. The metal loops for them are on the bag, I don’t see any reason one couldnt have been included. That said, straps are cheap enough to buy separately so it’s not a deal breaker. I’m really enjoying this bag and can easily recommend it.Variation: Color: Cream

4.0 out of 5 stars Sturdy lunch bag with tons of space!! This lunch bag is unlike any I’ve used before! First, some very strong pros:1. It is made of a very durable and light material! I am confident that many years of use will barely wear this down2. The inside is easily wipeable if anything spills, making it easy to clean3. The size is huge!! It can fit a full sized water bottle + snacks and utensils just on the top compartment, and on the bottom, a large lunch and more snacks4. It stays cold for long with one ice pack! Great insulation5. The zipper is dual sided, seems pretty reliableNow for the cons:1. It is expensive considering you can get a lunchbox at Marshalls or TJ Maxx for like $102. It has 2 clips for a shoulder strap, but it doesn’t come with one which is oddOverall, this lunch box is an excellent quality bag and you definitely get what you pay for!Variation: Color: Black
