How it Stacks Up
Your coffee and tea cup: hot all morning, cold all day, three lids and a handle.Tap any feature for the details.Hover any feature for the details.
| COLDEST 15oz | Others | |
|---|---|---|
| Cold 36+ hours
Rated 36+ hours ice-cold with the Chug lid closed, 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. | ||
| Leakproof lids
The Chug lid is 100% leakproof when closed, so it can ride in a bag. The Coffee and straw lids are made for sipping upright. | ||
| 3 lids in the box
A Coffee lid for hot drinks, a Sip (straw) lid with the Bunker, and a Chug lid with the Blendinator, which twists on to turn it into a shaker. | ||
| Built-in carry handle
An ergonomic handle sized to fit your hand, so even a full bottle is easy to carry. If it ever loosens, snug the two small screws under it. | ||
| Fits standard cupholders
The base drops into standard car, stroller and desk cupholders. In a tight console the handle can bump the trim: turn it toward the open side. | ||
| 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. | ||
| New designs every Thursday
New colors and art drop every Thursday at 9:45am ET, in limited runs. Glow designs charge in daylight or under a lamp and glow after dark. | ||
| Laser engraving available
Add a name or short phrase (up to 25 letters and numbers) with Personalize, above the add to cart button. Allow 3 to 5 extra business days. | ||
| Limited lifetime warranty
Covers manufacturer defects, temperature retention and the leakproof guarantee on drinkware bought at coldest.com. Wear and tear, drop dents and misuse are not covered. |
