Review Summary
Customer Images
Here's what customers have to say
The ice pack is generally well-received, with many praising its perfect size, ability to keep food cold for hours, and convenient fit in lunch boxes and coolers. Several customers noted it is great for 12L coolers and keeps food cold all day, even in hot weather. Many also appreciated how slim and sturdy the ice pack is, making it easy to pack. However, some found it melts relatively quickly, and a few were disappointed it didn't keep their food as cold as expected. Overall, the majority of reviewers were satisfied and found it to be a reliable and effective way to keep food and drinks cold.

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.

Medium Ice Pack
[This review was collected as part of a promotion.] Works well with the soft coolers. Keeps food cold all day. Don’t have to use the refrigerators at work.

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. . .

I absolutely love my slingback!
[This review was collected as part of a promotion.] I absolutely love my slingback! It holds my water bottle and all of my essentials-with room to spare! I not only use this when hiking or spectating at sporting events, but also while doing errands-so I can stay hydrated all day long!
