Wondering if the OG+ silicone boot fits other Ceres Chill bottles? Here's the truth about compatibility and what to expect.
Quick Answer
The OG+ silicone boot is designed specifically for the OG+ Chiller/Warmer, so it won't fit other Ceres Chill bottles like the Legacy OG or Demigoddess. If you're looking for protection for a different model, your best bet is to check the accessories designed for that specific bottle.

If you've invested in a Ceres Chill bottle, you know how important it is to protect it from drops and dings. The silicone boot is a popular accessory, but there's a common question: can you use the OG+ silicone boot with other Ceres Chill bottles?
The short answer is no, but let's dig into why that is and what your options are.
Why the OG+ Silicone Boot Isn't Universal
The OG+ Chiller/Warmer has a specific shape and size that the silicone boot is molded to fit. Other Ceres Chill bottles, like the Legacy OG or the Demigoddess, have different dimensions and designs. Even if a boot seems like it could stretch over another bottle, it won't provide a secure fit, which defeats the purpose of protection.
Ceres Chill designs accessories to match each bottle's unique form. The boot is no exception. Trying to force it onto a different model could leave gaps, cause the boot to slip, or even damage the bottle's finish. It's always best to use accessories made for your specific model.
- Check your bottle model before buying a boot: OG+ boots are only for OG+ bottles.
- If you have a Legacy OG or Demigoddess, look for accessories designed for those models.
What About the Demigoddess and Legacy OG?
The Demigoddess Mini Chiller/Warmer is a smaller, more compact bottle, so it has its own set of accessories. The Legacy OG, while similar to the OG+, has subtle differences in shape and size that mean the OG+ boot won't fit securely.
Ceres Chill offers a range of accessories for each bottle, including extra inner chambers and bundles. For example, the 6oz Inner Chamber is designed for the Demigoddess and can be used as a spare or a bottle. The Clean Feeding Bundle includes a chiller and other essentials, but it's not a substitute for a boot.
- Always match accessories to your specific bottle model.
- If you need protection for a Legacy OG or Demigoddess, check the product pages for compatible accessories.
What to Do If You Want Extra Protection
Even though the OG+ boot won't fit other bottles, there are still ways to keep your Ceres Chill safe. Consider a washbasin bag for travel, which protects your bottle and keeps it clean on the go. The All-You-Need Washbasin Bag is a lightweight, reusable option that works with any bottle.

You can also invest in extra inner chambers so you always have a clean, ready-to-use bottle. The 6oz Inner Chamber is great for daycare or fridge storage, and it works with the Demigoddess. For the OG+, extra chambers are available separately.
- Use a washbasin bag for travel protection.
- Extra inner chambers reduce the need for frequent washing and protect your bottle from wear and tear.
The Verdicts
- OG+ boot on Legacy OG: The Legacy OG has a different shape and size, so the boot won't fit securely. Don't force it; find a Legacy OG-specific accessory.
- OG+ boot on Demigoddess: The Demigoddess is smaller and more compact, making the boot incompatible. Check Demigoddess accessories for a proper fit.
- OG+ boot on CeresBFF editions: The CeresBFF OG+ is the same as the OG+, so the boot fits. The CeresBFF Demigoddess is not compatible. Know your model: OG+ or Demigoddess.
