The two sizes are perfect for my cooler bag—the smaller one tucks into the front pocket while the larger covers the bottom. I froze both overnight and my sandwiches were still cold at lunch, even after a few hours in the car.

The slim profile slides right into my lunchbox without squishing the sandwich, and after a full morning of errands the milk was still properly chilled. Honestly, the two size options made it easy to pick what fits.

Freeze it the night before and it’s still keeping my yogurt and turkey sandwich cold at noon, which is more than I can say for the flimsy gel packs I used to use. The slim design slides right into the side pocket of my cooler bag without taking up food space.
