Untethered Freedom. Uncompromised Luxury.
The Tumbler That Chills Your Drink.
Freeze the core. Fill your drink. Enjoy icy refreshment without dilution.
More Than a Tumbler
Most insulated tumblers only slow temperature change. CHILLCORE adds a reusable frozen cooling core, giving you a new way to actively chill drinks before carrying that cold with you.
Freeze. Fill. Shake. Chill.
Freeze the cooling core or lid assembly, fill CHILLCORE with your drink and give it a gentle shake to accelerate cooling. A simple routine turns everyday drinks into a more refreshing experience.
Fill
Add up to 20 oz of your favorite beverage when the cooling core is installed.
Shake
A gentle shake helps transfer the cold faster through the drink.
Chill&Enjoy

Room Temperature to Refreshing—Fast.
CHILLCORE is designed to rapidly cool room-temperature beverages. A gentle shake increases contact with the frozen core, helping deliver an icy drinking experience faster.
Cold Without Watering It Down.
Ice cubes cool by melting. CHILLCORE uses a sealed frozen core instead, helping preserve the drink you originally poured—from coffee and cola to beer and whiskey.
Cold Coffee. Full Flavor.
Enjoy chilled coffee without a glass slowly filling with melted ice water.
Keep It Crisp.
Cool cola without letting melting ice gradually weaken the taste.
Cold Where It Matters.

Ready for Another Refresh
A fully frozen core can continue delivering cooling performance beyond the first drink under suitable conditions.

Use CHILLCORE with the frozen core installed for active chilling, or remove the core and turn it into a full-capacity insulated tumbler for everyday hot or cold drinks.
