Why a stainless insulated bottle

Metal, vacuum, a closed lid. We quote owners. We do not invent a lab hour.

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 We do not publish a drop clock on this page.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.

No. We make 15oz, 24oz, 36oz and 46oz Limitless, plus the 20oz Tumbler, the 30oz Drive Thru, the 32oz GO and the 128oz Gallon. For a 40oz-class drink, pick 36oz or 46oz.
