Boon Frosh Breast Milk Chiller and Storage Bottle — Blue, 10 oz, Vacuum-Insulated & TSA-Friendly

The Boon Frosh Breast Milk Chiller is a compact, double-wall stainless steel bottle that keeps expressed milk cold for hours while serving as a dishwasher-safe storage container.

Busy caregivers need a reliable way to store and transport breast milk without hauling oversized coolers. The Frosh combines a slim, travel-friendly shape with a removable inner ice chamber and vacuum-insulated outer bottle so you can chill milk on the go, fit cup holders, and pass through airport security without hassle. It’s available in a 10 oz starting capacity and adapts to hold larger amounts when needed, making it a practical choice for outings, daycare drop-offs, or travel.

How does Frosh keep milk cold during a day out?

The Frosh uses a double-wall vacuum-sealed stainless steel shell with a separate inner chamber for ice or cold packs. This layered construction slows heat transfer so chilled milk stays cool for extended periods without adding bulky coolers to your bag.

• Double-wall vacuum insulation reduces temperature exchange.
• Inner ice chamber holds ice water to actively cool milk.
• Laboratory-tested scenario: keeps 10 oz cold up to 17 hours under typical conditions.

Can Frosh store different milk amounts and bottles?

Yes—its three-piece design adapts to multiple needs: use the smaller configuration for single feed portions or the expanded mode to hold pre-chilled larger volumes. That flexibility helps whether you’re pumping a quick 10 oz or transporting more milk for a longer outing.

• Compact setting holds about 10 ounces comfortably.
• Intermediate setting accepts 14 ounces for longer trips.
• Full-capacity mode stores up to 24 ounces of pre-chilled milk.

Is Frosh practical for travel and everyday cleaning?

Frosh was designed for mobility: its slim profile fits most car cup holders and it meets TSA rules for carry-on containers, so it’s convenient for flights. Cleanup is low-effort since the pieces are dishwasher-safe, letting you sanitize quickly between uses.

• Cup-holder-friendly shape and purse-friendly size.
• TSA-compliant for air travel when used properly.
• Dishwasher-safe components for easy sanitizing.

How long can Frosh maintain milk temperature for feeding?

While optimized for chilling, Frosh can also maintain warmer temperatures for short periods, helpful when transporting freshly expressed milk or prepared formula. For cold storage, expect extended cooling when the inner chamber contains ice; for warmth, it will slow cooling for a few hours depending on starting temperature and ambient conditions.

• Cold: up to 17 hours for a 10 oz load in tested conditions with ice.
• Warm: holds milk or formula at feeding temperature for several hours.
• Performance varies with ambient temperature and how the inner chamber is prepared.

Who is this for: The Boon Frosh is ideal for nursing parents and caregivers who need a low-profile, reusable milk chiller that fits everyday life—commuters, parents running errands, travelers, and anyone adding a practical piece to a baby registry. If you want an easy-to-clean, TSA-friendly solution for keeping breast milk chilled without a bulky cooler, Frosh offers a flexible, portable option.
