“the large size lets me stay hydrated at work all day”
Debbie, verified buyer Overnight
Cold up to 36+ hours*
Triple-wall vacuum insulation keeps the ice in your water with the Chug or Sports lid closed.
“I forgot it on my desk when I left work and when I came in the next morning there was still ice in my water!”
Emeline, verified buyer In the car
Fits 99% of cupholders
The base fits 99% of car cupholders. It's tall and heavy when full, so a shallow holder can let it lean on sharp turns.
“Also I really like that it can fit into my car's cup holder, a quality of life feature I didn't know I needed.”
Arnold, verified buyer On the move
A handle built for a full bottle
A built-in handle sized for your hand, so even 46oz of water is easy to carry.

| COLDEST 46oz | Others | |
|---|---|---|
| Cold 36+ hours
Rated 36+ hours ice-cold with the Chug or Sports lid closed (24+ with the open straw lid), 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 and Sports lids are 100% leakproof when closed, so it can ride in a bag. The open straw (Sip) lid is for sipping upright and can leak if the bottle tips. | ||
| 3 lids in the box
A Sports lid (flip-up straw), a Sip (straw) lid and a Chug lid with a built-in fruit infuser: one bottle for sipping, chugging and infused water. | ||
| 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 99% of cupholders
The non-slip base fits 99% of car cupholders. At 46oz it's tall and heavy when full, so a shallow holder can let it lean on sharp turns. | ||
| 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. |
