[This review was collected as part of a promotion.] The slim blue ice packs are very easy to slip in a lunch bag or cooler. They last all day so if you are trying to keep beverages cold they will do the trick. They are very compact so if you are trying to pack light they work well for that too. Just slip 1 slim blue ice into a bag & go. At lunch your food will still be cold.

My husband, our two sons, and I all use these ice packs regularly, I think we have about 12 total. We love that they are thin and fit so easily in any lunch box. We typically put one on the top and one on the bottom. These will definitely keep your meal cold until lunch time, but are not all-day ice packs, so I wouldn't recommend them if you are trying to go more than 4-5 hours. They are also great for sports, we always throw a couple in a cooler in case of injuries at any practice or game and they have come in handy more than once!

[This review was collected as part of a promotion.] We love these little ice packs. Very thin but they stay cold for a long time. We used them all the time. They freeze pretty quickly because they’re small! We used them in a cooler bag and they keep our food and drinks cold all day.

[This review was collected as part of a promotion.] These slim ice packs are new to me. I have years of experience with larger and/or thicker packs and, in general, they worked well in large coolers but not so much in smaller lunch totes. This slim ice pack seems to have solved the problem The pack lays flat in the bottom of my tote, and though the thin size doesn't stay cold for as long as the thicker packs, it's plenty for lunch. Nice idea.

[This review was collected as part of a promotion.] It fits perfectly in my son's lunch box for school. We still have room for all of his lunch without having to decide what can't fit because of the bulky ice packs. It also stays cold longer than I thought it would with the small design.

[This review was collected as part of a promotion.] I am loving these ice packs. They don't take up too much space inside the kids' lunch boxes but still keep their food cold until lunchtime. Yes they fit just right in the mesh zip up pocket inside the Pottery Barn lunch boxes! Just one inside a small lunch box won't last all day, but definitely the 4 hours until lunch.

[This review was collected as part of a promotion.] Love these slim ice packs. They are the perfect size for my soft insulated lunch bag and keep everything nice and cold. The size and shape is what's particularly awesome about them. Very convenient on the go!

[This review was collected as part of a promotion.] The Bentgo - Set of 4 Slim Ice Packs - Blue goes great with the Deluxe Bentgo Lunch Bag . They stay frozen in my lunchbox at room temperature for about 6 to 8 hours.I like the thin design that is not bulky and does not take a lot of space in the lunch bag. It is easily cleaned and refreeze fast for next day. I would diffidently recommend.
