20oz Tumbler

Tumblers

A COLDEST tumbler is the 20oz Tumbler: stainless steel, a clear sliding lid, rated up to 20+ hours* cold and up to 13+ hours* hot. Andrea: it keeps drinks cold, doesn't leak, and is very cute. Olivia uses it when she wants a small amount instead of a large water bottle. The 20oz Tumbler is final sale. We do not make a 40oz tumbler — pick a 36oz or 46oz Limitless for that class. A handle-and-lid coffee mug is insulated coffee mugs.

Why the 20oz Tumbler

A cup, not a bottle. We kept the live set.

  • Cold drinks, no leak on the slide

    Andrea: keeps drinks cold, doesn't leak, very cute. Glowie Meow is a confirmed glow design.

    ★★★★★

    I am so happy to find something that keeps my drinks cold, doesn't leak, and is very cute! … The Glowy Meow is the only insulated tumbler I've ever liked.

  • Smaller than a large water bottle

    Olivia uses it when she wants a small amount instead of her large water bottle.

    ★★★★★

    It is great for keeping my water cold when I just need a small amount instead of using my large water bottle.

  • Not a 40oz

    We do not make a 40oz tumbler. 36oz and 46oz Limitless sit either side. The 30oz Drive Thru is a separate product.

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 We do not publish a drop clock on this page.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.
Is it dishwasher safe?
We recommend hand washing. Printed, glitter, glow and glossy finishes are not dishwasher safe.
Is it leak-proof in a bag?
The Chug and Sports lids are 100% leakproof when closed. The Sip straw lid can leak if tipped. The 20oz Tumbler sliding lid is splash-resistant, not leakproof.
