| COLDEST Gallon | Others | |
|---|---|---|
| Cold 36+ hours
Rated 36+ hours ice-cold with the lid closed, and a gallon packed with ice holds it far longer, thanks to triple-wall vacuum insulation. A plastic bottle has no insulation, so ice is gone in hours. | ||
| Hot 13+ hours
Coffee, tea and cocoa stay hot 13+ hours. Hot liquids build pressure: open the lid slowly, pointed away from you. | ||
| A full gallon, insulated
128oz: a full day of water in one fill, with triple-wall vacuum insulation. A plastic gallon jug isn't insulated. | ||
| Leakproof lids
A lab-tested, 100% leakproof seal with the lid screwed on tight. | ||
| Built-in carry handle
A padded carry handle built for a full gallon (water alone weighs about 8.3 lb). | ||
| No sweat, no metal taste
Pro-grade 18/8 stainless steel with BPA-free lids: the outside stays dry and drinks taste like drinks. Plastic sweats with ice and can hold on to flavors. | ||
| A surprise design
Each order is one randomly selected Gallon colorway from 100+ possible, and it can be a v7 or a v8 Limitless. You can't pick or exchange the design. |
Product FAQ: Answers from COLDEST
How does the mystery Gallon work?
You get one genuine COLDEST Gallon in a randomly selected colorway, from 100+ possible designs, with the same insulation and lids as every Gallon. Mystery bottles can be a v7 or a v8 Limitless.
Can I choose or exchange the design?
No. The design is random, so it can't be picked or exchanged, and you might get one you already own. Each design has under a 1% chance per order.
How long does the COLDEST Gallon keep drinks cold?
Up to 36+ hours ice-cold with the lid closed, and a gallon packed with ice lasts far longer: reviewers report ice still in it after two days in a hot car. For the longest cold, fill it with ice first and top it up with cold water.
Can I use it for hot coffee or tea?
Yes. It keeps drinks hot for 13+ hours. Use care with hot liquids: pressure can build inside, so open the lid slowly and pointed away from you.
Why is my ice melting faster than I expected?
Hold times assume a bottle packed with ice and a closed lid. An open straw lid, a bottle that's mostly water, or a refill of room-temperature water all shorten them. Fill it with ice first, top it up with cold water and keep it closed. If your bottle still doesn't hold cold like it should, contact our team.
See all 18 FAQs
Is it leakproof?
Yes. The lid has a lab-tested, 100% leakproof seal when it's screwed on tight. If you ever see drips at the threads, unscrew it, check that the gasket sits flat, and screw it back on until it stops.
Does the Gallon fit a cupholder?
No. A full gallon is built to carry, not for cupholders: use the padded handle. For a cupholder bottle, choose the 36oz or 46oz Limitless.
How heavy is it when full?
A gallon of water alone weighs about 8.3 lb, so a full Gallon is a real carry. The padded handle makes it easy on your hand.
Which size should I get?
15oz: your coffee and tea cup. 24oz: the lighter everyday bottle. 36oz: the original all-day size. 46oz: the most water per fill that still fits a cupholder. 1 Gallon: a full day of water in one fill (too big for cupholders). Every size has a carry handle.
Is it dishwasher safe?
We recommend hand washing to protect the finish and the insulation: printed, glitter, glow and glossy designs are not dishwasher safe. Wash the bottle and lids with warm soapy water. To deep-clean a lid, soak it for 30 minutes in warm water with a little dish soap or vinegar, rinse, and air-dry it open. Never freeze or microwave the bottle.
How do the Glowie designs glow?
Glowie finishes charge in daylight or under a lamp and glow softly once the lights go out. The glow fades through the night and recharges the next day.
What is it made of?
Pro-grade 18/8 stainless steel with triple-wall vacuum insulation and BPA-free lids. No metallic taste, and no sweating on the outside.
Can I return it?
This is a final-sale item, so it can't be returned or exchanged. If it arrives damaged or defective, contact our team. Details: Warranty & Returns.
Do you make a bottle without a handle?
Is the Mystery Gallon covered by the Coldest warranty?
No. Mystery items are excluded from all warranty coverage, so the Limited Lifetime Warranty on Coldest drinkware does not apply to them. For any question about your order, contact support@coldest.com.
Can young children use it?
Kids under 8 should use it only with adult supervision. It has small parts that are a choking hazard, as listed under Care & Warnings on this page.
When do new Coldest designs drop?
New limited-edition drops release every Thursday at 9:45am Eastern, and most drops are gone once they sell out. A mystery bottle is for a surprise colorway; the drops are where you pick a design.
How will I know when my order ships?
You will get an email with a tracking number when your order ships. For any question about your order, contact support@coldest.com.
