母乳クーラー用アイスパック

The 24-hour chill time is no joke—I pumped at 6 a.m., popped this pack in the cooler, and the milk was still ice-cold when I got home from work. It’s also skinny enough that it doesn’t hog space in the cup, which is exactly what I needed.

I’d forgotten how nice it is to have a backup cold source that doesn’t require constant ice refills—this one held milk safely chilled the whole day at work, and slipping it into the cooling cup was effortless. Even the smaller cooler fit it without any awkward bulging.

The fit was the big win for me—it slides into both my 16 oz. and 25 oz. bottles without any wrestling. I only wish the chill held a touch past the 24-hour mark on hotter days, but for a backup it’s done the job every time.
