Claire ★★★★★

Filled the inner chamber with ice cubes this morning for a road trip, and my 28oz of milk stayed cold for the full 24 hours. The capacity is seriously impressive—enough for my toddler’s bottles and my coffee creamer. Honestly, it’s a game-changer for long days out.

Emma X. ★★★★★

I've been using the inner chamber freeze method and it kept my milk cold for over 20 hours on a hot day trip. The 28-ounce capacity is a game changer for me since I don't have to refill constantly.

Carter W. ★★★★★

Finally got 28 ounces to stay cold for a full day without any ice melt mess—the frozen inner chamber is a game changer. I’ve been using it for overnight shifts and my milk is still properly chilled 12 hours later.
