CERES CHILL OG+ Breastmilk Chiller & Warmer — 12–38oz Portable Pump-Compatible Bottle, Two Chilling Options

The CERES CHILL OG+ is a pump-compatible, all-in-one breastmilk chiller, warmer, and feeding bottle that stores 12–38 oz and keeps up to 28 oz cold for 24 hours without bulky coolers or cords.

Designed by a mom-founded brand, the OG+ updates the original Ceres Chiller with greater capacity, fully dishwasher-safe parts, and two chilling options—use ice or a freezable inner chamber—so you can adapt to workdays, travel, and overnight shifts. It combines an insulated outer chamber and a removable inner bottle that connects to most narrow-neck pumps for single or double pumping, and converts to a feeding bottle with a standard nipple.

How does the OG+ keep milk cold on long outings?

The OG+ uses two chilling methods to fit different routines: pack ice in the outer chamber for TSA-friendly travel or pre-freeze the inner chamber for extended shifts. Either option slows temperature rise so milk stays chilled up to 24 hours when using the freezable inner chamber and up to 12 hours for maximum combined capacity.

• Use ice in the outer chamber for airport security and refills on-the-go.
• Pre-freeze the inner chamber for long shifts without access to refrigeration.
• Holds up to 28 oz chilled for 24 hours or 38 oz already chilled for shorter periods.

Can I pump directly into the OG+ and feed from it?

Yes—the OG+ is designed to accept most major narrow-neck pumps directly, letting you pump into the inner bottle to reduce transfers and spills. After pumping, detach the connector, add a standard nipple, and feed straight from the same container for fewer parts and quicker feeding.

• Includes inner bottle, cup, and connector for pump compatibility and double pumping.
• Attaches to standard nipples for direct feeding—no extra bottles required.
• Wide-neck pumps may need a universal converter (not included).

How does the OG+ work as a warmer and multi-use bottle?

Beyond chilling, the OG+ can warm milk by adding hot water to the outer chamber; heat transfers to the inner bottle until feeding temperature is reached. Its durable, BPA/BPS/DEHP/PFAS-free construction also makes it suitable for everyday hot or cold drinks once the pumping phase is over.

• Add hot water in the outer chamber to gently warm milk in the inner bottle.
• Suitable for reheating and for later use as a travel beverage container.
• No cords or electric warmers needed—portable and simple to use anywhere.

What makes cleaning and travel easier with the OG+?

The OG+ breaks down into five parts that are fully dishwasher-safe, making cleanup fast between uses. Its compact, cordless design is TSA-friendly and slips into diaper bags without the bulk of a separate cooler or multiple freeze packs.

• Five dishwasher-safe parts for quick sanitizing and routine cleaning.
• TSA-approved dimensions and ice-compatible outer chamber for air travel.
• No extra cooler bag, freeze packs, or cords required—designed for daily life.

Who is this for: The CERES CHILL OG+ is ideal for pumping parents who need a single, portable system that handles pumping, cold storage, warming, and feeding—whether commuting to the office, traveling by air, or working long shifts. It’s best for users of narrow-neck pumps who want to reduce bottle transfers and streamline their routine, and for anyone who values dishwasher-safe parts and TSA-friendly travel features.
