Leak-proof water bottles

With the Chug or Sports lid closed, a COLDEST bottle is 100% leakproof, so it can ride in a bag, a backpack or on the car seat. All three lids of the 32oz GO are leakproof when closed, the 6.7oz Bottle is leakproof with its straw pushed all the way down, and the Limitless Gallon seals when its lid is screwed on tight. The Sip (straw) and Coffee lids are made for sipping upright and can leak if the bottle tips, so switch to the Chug or Sports lid before it goes in your bag.

Seal it right

Leakproof in your bag, every time

Four habits that keep your bag dry.

  1. A white and grey hex-print 46oz COLDEST Limitless with its white Chug lid closed, on a counter1Doug

    Close the Chug or Sports lid

    These are the lids made for a bag: the COLDEST Chug and Sports lids are 100% leakproof when closed.

  2. Screw it on until it stops

    Turn the lid until it stops, without forcing it. Check that the silicone seal sits flat inside the lid and the threads are clean.

  3. Click the spout shut

    On the Sports lid, make sure the flip spout clicks shut before the bottle goes in a bag.

  4. Keep straw and coffee lids upright

    The Sip (straw) and Coffee lids are made for sipping upright and can leak if the bottle tips. On the 6.7oz, push the straw all the way down.

Questions

Leak-proof bottle questions, answered

Leakproof lids

Is the COLDEST water bottle leakproof?
Yes, with the right lid closed. The COLDEST Chug and Sports lids are 100% leakproof when closed, so the bottle can ride in a bag or backpack. Screw the lid on until it stops and make sure the flip spout clicks shut.
Which COLDEST lids are leakproof?
The Chug lid on every Limitless from 15oz to 46oz, the Sports lid on the 36oz and 46oz, all three 2.0 lids on the 32oz GO, the 6.7oz straw lid with the straw pushed all the way down, and the Gallon lid screwed on tight. The Sip (straw) and Coffee lids are made for sipping upright.
Is there a leak proof water bottle with a straw?
Yes. The COLDEST Sports lid on the 36oz and 46oz Limitless has a flip-up straw and is 100% leakproof when closed, and the Sports Lid 2.0 on the 32oz GO is leakproof when closed too. The Sip (straw) lid is for sipping upright and can leak if the bottle tips.
Does the straw lid leak?
The Sip (straw) lid is made for sipping upright, so it can leak if the bottle tips over. Before the bottle goes in a bag, switch to the Chug or Sports lid. On the 6.7oz, push the straw all the way down.
Is the coffee lid leakproof?
The Coffee lid on the 15oz and 24oz is made for sipping upright. For a bag, switch to the COLDEST Chug lid, which is 100% leakproof when closed.
Is the 20oz Tumbler leakproof?
No: its clear sliding lid is splash-resistant, made for sipping upright at your desk or in a cupholder, not for tossing in a bag. For coffee that goes in your bag, the 15oz Limitless has a COLDEST Chug lid that is 100% leakproof when closed.

Cold, hot and care

Does a leak-proof bottle keep drinks cold?
These do. Every bottle on this page keeps drinks ice-cold for up to 36+ hours* with the lid closed, thanks to triple-wall vacuum insulation: see bottles that keep ice cold.
Can I carry hot drinks in it?
Yes: they keep drinks hot for up to 13+ hours*. Hot liquids build pressure, so open the lid slowly, pointed away from you.
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. 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.

Bags, kids and cars

Can I put it in my purse or backpack?
Yes, with the COLDEST Chug or Sports lid closed: both are made to ride in a bag. Screw the lid on until it stops, click the spout shut, and keep straw and coffee lids for sipping upright.
Is there a leak proof water bottle for kids?
The 6.7oz Bottle is leakproof with its straw pushed all the way down, so show little ones how to push it back down before it goes in a bag. For a full school day, the 15oz Limitless has a leakproof Chug lid. The 6.7oz lid has small parts, so children under 8 should use it with adult supervision.
What is the best leak proof water bottle that fits in a cup holder?
The 36oz and 46oz Limitless and the 32oz GO fit 99% of car cupholders. On the Limitless, close the COLDEST Chug or Sports lid, which are 100% leakproof when closed; on the GO, all three 2.0 lids are leakproof when closed.
Does the Gallon leak?
No, when the lid is screwed on tight: the COLDEST Gallon lid has a lab-tested, 100% leakproof seal. If you ever see drips at the threads, unscrew it, check that the gasket sits flat and screw it back on until it stops.

If it leaks

Why is my COLDEST bottle leaking?
Check that the silicone seal sits flat inside the lid and the threads are clean, then screw the lid on until it stops, without forcing it, and make sure the spout clicks shut. A Sip (straw) or Coffee lid can leak if the bottle tips: they're made for sipping upright.
My leakproof lid still leaks. What should I do?
If a closed Chug or Sports lid still leaks, or a lid won't latch, start a claim through our return portal with a photo or a short video. The limited lifetime warranty on drinkware bought at coldest.com covers manufacturer defects, including the leakproof guarantee; lost lids and damage from drops aren't covered.
