      Worth the wait

      Samantha at Coldest turned a denied warranty claim into a goodwill Mystery Bottle, and it was worth the wait. 36 oz, straw lid, solid handle, and it fits my truck's cup holder nice and snug — doesn't rock around or fall over. Good customer service, and I'm happy with the replacement.

      The design is a mystery, but the quality is not.

      These bottles do not disappoint! I have tried so many different brands and these are top notch. They hold ice for ages! I can just keep refilling my tea and the ice is still in there. Im beyond impressed.

      Unexpected beauty

      I had already purchased a COLDEST tumbler and I loved it so much, I thought I would get another. I chose mystery tumbler because I figured I wouldn’t be disappointed and I wasn’t. It was in line with the Halloween season and perfect for my use.

    COLDEST 36oz vs. the rest

    COLDEST 36oz compared with others
    COLDEST 36ozOthers
    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
    Three interchangeable lids. Mystery bottles can be a v7 or a v8, and the lid set depends on which one you get.
    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. It's a tall bottle, 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.
    A surprise design
    Each order is one randomly selected 36oz colorway from 100+ possible, and it can be a v7 or a v8 Limitless. You can't pick or exchange the design.

    Product FAQ: Answers from COLDEST

    How does the mystery 36oz work?
    You get one genuine COLDEST 36oz in a randomly selected colorway, from 100+ possible designs, with the same insulation and lids as every 36oz. Mystery bottles can be a v7 or a v8 Limitless.
    Can I choose or exchange the design?
    No. The design is random, so it can't be picked or exchanged, and you might get one you already own. Each design has under a 1% chance per order.
    How long does the COLDEST 36oz keep drinks cold?
    Up to 36+ hours ice-cold with the Chug or Sports lid closed (24+ with the open straw lid), thanks to triple-wall vacuum insulation. For the longest cold, fill it with ice first, top it up with cold (not room-temperature) water and keep the lid closed between sips.
    Can I use it for hot coffee or tea?
    Yes. It keeps drinks hot for 13+ hours. Use care with hot liquids: pressure can build inside, so open the lid slowly and pointed away from you.
    Why is my ice melting faster than I expected?
    Hold times assume a bottle packed with ice and a closed lid. An open straw lid, a bottle that's mostly water, or a refill of room-temperature water all shorten them. Fill it with ice first, top it up with cold water and keep it closed. If your bottle still doesn't hold cold like it should, contact our team.
    See all 16 FAQs
    Is it leakproof?
    Yes, with the Chug or Sports lid closed: both are 100% leakproof, so it can ride in a bag or backpack. Screw the lid on until it stops and make sure the flip spout clicks shut. The Sip (straw) lid is made for sipping upright and can leak if the bottle tips over.
    What lids come with it?
    Three interchangeable lids. Mystery bottles can be a v7 or a v8 Limitless, and the lid set depends on which one you get.
    Will the 36oz fit my car's cupholder?
    Yes. The non-slip base fits 99% of car cupholders. It's a tall bottle, so in a shallow holder it can lean on sharp turns.
    Which size should I get?
    15oz: your coffee and tea cup. 24oz: the lighter everyday bottle. 36oz: the original all-day size. 46oz: the most water per fill that still fits a cupholder. 1 Gallon: a full day of water in one fill (too big for cupholders). Every size has a carry handle.
    What if the handle feels loose?
    There are two small screws under the handle. Tighten them clockwise with any small screwdriver until snug; don't overtighten. If it still won't hold, contact our team.
    Is it dishwasher safe?
    We recommend hand washing to protect the finish and the insulation: printed, glitter, glow and glossy designs are not dishwasher safe. Wash the bottle and lids with warm soapy water. To deep-clean a lid, soak it for 30 minutes in warm water with a little dish soap or vinegar, rinse, and air-dry it open. Never freeze or microwave the bottle.
    Does it work with CIRKUL flavor cartridges?
    Yes. The Limitless handle bottle fits CIRKUL lids, as well as COLDEST wide-mouth lids.
    How do the Glowie designs glow?
    Glowie finishes charge in daylight or under a lamp and glow softly once the lights go out. The glow fades through the night and recharges the next day.
    What is it made of?
    Pro-grade 18/8 stainless steel with triple-wall vacuum insulation and BPA-free lids. No metallic taste, and no sweating on the outside.
    Can I return it?
    This is a final-sale item, so it can't be returned or exchanged. If it arrives damaged or defective, contact our team. Details: Warranty & Returns.
    Do you make a bottle without a handle?
    Yes. The 32oz GO is our slim, handle-free bottle made for cupholders, and the Universal is our handle-free, shaker-shape bottle. Both use the same triple-wall insulation.
