Review Summary
Customer Images
Here's what customers have to say
The ice pack is effective at keeping food and drinks cold for hours, even in hot weather. Customers find the compact, slim design to be a good fit for lunch boxes and small coolers. However, some users report the ice pack melts faster than expected, especially during extended use or in more demanding situations. A few customers also felt the ice pack was too thick and bulky. Overall, the ice pack appears to be a reliable cooling solution for everyday use, but may not be the best choice for extended outdoor activities.

Ice pack
[This review was collected as part of a promotion.] I bought the ice pack to be used with the cooler. It works well & I like the fact that it has a handle. It keeps my drinks cold all day!

Fits perfect but a little thick
[This review was collected as part of a promotion.] It could be at least a quarter of an inch thinner and still provide the same cooling. But I like how it fits perfectly inside the 8L lunch bag i bought with it.

Blue
[This review was collected as part of a promotion.] The stainless steel container keeps everything much colder and the lid is secure and tight, as I would expect from all the great products HydroFlask sells. . .
