Overview
Description
Boon’s FROSH Milk Chiller gives parents on the go an easy way to store milk and keep it chilled on the go. The compact size slips easily inside a diaper bag or purse, and the double wall vacuum seal keeps milk cold for up to 17 hours.
Simply fill FROSH with ice water and pour your milk into the double wall vacuum sealed stainless steel. It’s adaptable and can hold 10, 14 or 24 ounces of breastmilk.
FROSH keeps milk warm, too: can be used to maintain the temperature of fresh breast milk for up to six hours.

Q&A
Have a question? Ask an expert.
Start typing and see existing answers.
Can it keep pumped milk from the day prior still fresh for 17 hours if then transferred from fridge to this bottle?
Best Answer: Yes. If the milk has been stored safely in the refrigerator first, you can transfer it to the Boon FROSH for travel. The FROSH is specifically designed to hold up to 24 oz of pre-chilled breast milk and keep it cold for up to 17 hours when used with ice as directed.
Just keep in mind that the 17-hour claim assumes proper use (adding ice and following the instructions) and starts with already chilled milk. The FROSH doesn't extend the overall safe storage life of breast milk—it simply helps maintain a safe chilled temperature during transport.

Doesn't stay cold
Was so excited to get this and I froze the outside canister with water in it and the inside canister became deformed.. it doesn't stay cold very long even in the fridge.

Perfect travel companion
Traveling in the car for almost 5 hrs one way is already a hard feat, but with a breastfed 2 month old it’s much more difficult. I am so glad I got this item for Christmas as it kept our liquid gold cold for the entire trip. Especially with the cold winter weather. I will never travel without this bad boy again.

The best alternative to nighttime refrigeration
I love the portability of my frosh as well as the three different options for breast milk ounces and the 2 different storage options. Best investment and saves me a zombie like walk to the fridge with late night pumping.

So happy I purchased this storage bottle. This helped me out tremendously with traveling (flying). TSA had no issue with passing it through the airport.
