Best water bottles

We do not publish a ranked best water bottle. Owners keep writing that a COLDEST Limitless is the one they keep: Laura still had ice-cold water from yesterday; Joanne said none of her old bottles compare; Melisa called the 46oz the best tumbler. Rated up to 36+ hours* cold with the lid closed. This collection's live set is the 36oz and 46oz Limitless plus the 36oz and 46oz Universal. The 36oz Universal and the 46oz Universal are final sale: no Personalize, no limited lifetime warranty.

  • Ice still there the next day

    Laura still had ice-cold water from yesterday on her nightstand. Lori (on a 24oz, not in this set) still had ice on Wednesday.

    ★★★★★

    I had no idea how spectacular Coldest water bottles were until I got one. … Right now I have ice cold water from yesterday on my nightstand.

Stock and the rest

Do sold-out designs come back?
Most COLDEST designs are a single limited run. A few have come back in a new size. We never promise a restock. Sign up for restock alerts on the product page if you want an email when that size returns.
How do I hear if a sold-out size returns?
Open the product page for that size and sign up for restock alerts there. That is an alert, not a promise.
Can I still get a retired design?
Some retired designs appear in the Mystery bottle pool. The published odds are on the Mystery product page. No specific design is guaranteed.
When do new limited designs come out?
New limited designs show up on Latest Drops when they launch. We do not publish a drop clock on this page.
How long does it keep a drink cold or hot?
Up to 36+ hours* cold on a Limitless, the 32oz GO or the Limitless Gallon with the lid closed; the 20oz Tumbler is up to 20+ hours* cold and up to 13+ hours* hot.
