Coolflask Lifetime Warranty Guarantee

Coolflask believes a good bottle should last a lifetime, and we want to make sure yours does too! That’s why we offer Coolflask Lifetime Warranty and 100% customer satisfaction guarantee.

Our warranty covers all Coolflask products to protect against manufacturing defects. Why? Because our priority is to ensure customer satisfaction and confidence in the durability of our products. The Coolflask guarantee of high quality sustainability products means you can expect a replacement or refund if your purchase has any manufacturing defects.

What Does Our Lifetime Warranty Cover?

When you purchase a lifetime warranty water bottle (including tumblers and accessories), you can rest assured that it covers manufacturing defects such as leakage, insulation flaws, or rattling noise. Please note that any damage caused by misuse, wear and tear, and any modifications does not fall under manufacturing defects as per Coolflask warranty. Also, warranty claims are only approved if the product is purchased from an authorized seller.

With a lifetime warranty from Coolflask, your purchase is protected even before it gets to you — we’ll cover any damage during shipping. We understand that it's not ideal after some anxious waiting only to find your new bottle damaged upon arrival. If your Coolflask was purchased through our website and then damaged during transit, please send us an email at marketing@thecoolflask.com. If you purchased your bottle through another seller such as Amazon, please request a refund from Amazon and state the reason as "damaged during transit."

One Important Note: What Our Warranty Does Not Cover

Please remember that our lifetime warranty only covers manufacturing defects. Our warranty does not cover damages caused by improper use, cleaning, modifications, or wear and tear. We will provide an exact replacement for your bottle or accessory when a warranty claim is approved.

What Is Our Warranty On Accessories?

We are glad you asked! ALL of our products come with lifetime warranties.

Lid Sets: Our spout and straw lid sets come with a lifetime warranty against leakage or other malfunctions including "bad water flow" which is when straws let out air or bubbles.

Paracord Handle: Our handles come with a lifetime warranty against manufacturing defects and malfunctions.

Love Your Coolflask Through and Through

The majority of questions we receive are related to the care of our bottles. Remember that the beautiful powder coat on your Coolflask does not do well in the dishwasher. Here are a couple of tips on how to properly care for your favorite bottle:

  • Use warm soapy water to wash your bottle sinside and out.
  • Never put the bottles in the dishwasher, the wash process might affect the powder coat on your bottle.
  • For a little extra cleaning power, put ¼ to ½ cup of distilled vinegar inside the bottle and gently swirl it around. Let it sit for 5 to 10 minutes. This quick tip helps remove spots inside the bottle. For hard to remove spots,mix 3 teaspoons of baking soda with a little bit of water and use a gentle brush.
  • What about the lids? Lids are dishwasher safe. We also recommend cleaning your lids and straws with a gentle, size appropriate brush.
