The straps on this is easily adjustable. Keeps my food cold for a solid 8 to 10 hours. Sturdy and east to use, though it is a little bulky. The only real problem I can think of is the zippers can be a little difficult sometimes, but overall this is a great purchaseThe only reason this got 4 stars is due to its size. I wish a bigger size for the same bag was available.It stinks this beautiful lunch bag didn’t last. This was bought may 11th 2021 (just over a year ago) and it’s been falling apart for a few months. Time to throw it in the trash and get a different brand.Super cute lunch bag! Keeps things cold for a long time. The yellow color is great! It has a pocket on the front for utensils, napkins, etc. Easy to wipe down the inside for cleaning. I only took off one star because it doesn't fit as much as I was expecting and I needed a bag that fit lunch, snack, and 2 drinks for me to take to work. The main zipper opening is narrow so it's difficult to fit my bentgo box in. I kept this for days when I only bring snacks and bought another one that's larger. Overall, very good lunch bag.The lunchbox itself seems fantastic! It’s a lot bigger than I thought (see picture with Yeti). There’s plenty of room for food and snacks, as well as a large outside pocket for your phone or napkins. The zippers and strap/handle feels really well made. The colors are vibrant and the pattern looks great! However due to the way the lunchbox was folded for shipping it is very difficult to unzip the compartments and it’s lumpy/awkward right now. I’m sure after I shove it full of Tupperware a few times it’ll regain its structure but I was disappointed in that. Hopefully the zipper works fine in the future as it straightens out. I will update after a few weeks.My kiddo picked this out and it seems really good quality. No odor which has been an issue with other lunch bags. The inside seems like a good quality material, too. Will update if it any quality issues arise.Update: we have the 4L and it feels small. I'm able to fit a water bottle and 1 container (her snack). I don't think I can get a whole lunch, snack and water bottle in the bag. (Granted, I do a lot of chopped fruit and veg which takes up more space than packaged snack foods.) Go bigger, better to have more space than less.The bag doesn't open very wide. If you put a water bottle or soda in it, it fills up a good amount of space. It's nice for just a lunch but will not hold a 9 hour work day worth of food.I was replacing an existing lunch bag and was looking for a particular size/shape, this bag fit the bill. The quality of the bag is superior, not flimsy at all. The thermal properties are great, keeping things either cold or warm perfectly. For me, the only thing is it's actually so thick with thermal protection, it makes the bag a little stiff, not as simple to just throw my containers in there. That being said, I would just recommend going with a slightly larger size and issue solved!Love itThis is great, and huge. Intend to pack large package of fruit of veg and the bottom compartment is excellent for my large size glass storage container with still a top compartment for more plus the top compartment fits a full size water bottle!The glass containers are save inside from bumps and drops as well as it is so well insulated and durable. I love this.Excelente calidad, sin embargo tengo 2 meses con ella la uso normal nada rudo y ya se comenzó a romper parece como si en la costura de esa parte no agarro el material. Desafortunadamente ya paso el tiempo de devolución ☹️ Pensé que me duraría más tiempoIt’s pretty nice and I like the inside cause whenever you spill water you can clean it and you don’t have to wait for it to dry and it’s Really good my daughter really likes it!
