ZhiChu 2-Pack Cooling Gel Tube for Breast Milk — 24H Cold Retention & 360° Cooling

Reliable, ice-free cooling for breast milk on the move

The ZhiChu cooling gel tubes are built for busy parents who travel, work, or nurse away from home. With 360° surround cooling and gel-based technology, they help keep milk cold without ice, so you can focus on the moments that matter.

Each pair is designed for portability and ease, fitting into most portable breast milk coolers and storage bottles. The result is a simple, reliable way to maintain a cold environment while you’re on the go.

How it works

Freezing the tubes takes about 12 hours at around 0℉. Then place them in your cooler bottle or storage bottle. The gel-tube circulation surrounds contents from every angle, promoting steady cooling across the entire interior.
