All bottleworx products keep beverages (and food) either hot OR cold.

We use the best stainless steel available. It resists absorption, thereby eliminating the "metal" taste, and dramatically reducing flavor transfer.

All bottles come with the Travel/Carry Lid, plus ONE FREE Drinking Lid. Chose from Sport Cap, Hot Lid, or Straw Lid. Additional lids are available for purchase.

We specialize in Custom and Corporate Engraved Bottles. Great for Corporate Gift Giving, Tournaments and other Special Events, Conferences, Fundraisers, etc. See our Custom Section for more information.

We are so convinced that bottleworx is the best double wall vacuum insulated bottle available that we guarantee every bottleworx product against manufacturer defects for life!

If you have a warranty claim, please email or call bottleworx or visit the vendor that your bottleworx product was purchased from.

Although our lifetime warranty does not cover regular wear and tear, such as dents, scratches, powder coat chips from the bottle being dropped or damaged, it does cover manufacturing defects, such as:

Broken or leaking caps: If your cap breaks or you notice a leak, do not send your flask to us. Instead simply email us. Please note you may be required to send us a photo of your cap to validate the claim. You will be responsible for the shipping charge to have the flask returned.

Bottles that no longer insulate: You can test the insulation property of your flask at home by adding boiling hot water to the flask. After 5 minutes, feel the outside of the flask (below the neck). If you feel any hot spots, the vacuum has been compromised and you are eligible for a replacement.

Bottles that are damaged during the shipping process: Please contact us if you ordered your item from bottleworx.com and it arrived damaged. If you use your bottle, we cannot replace it due to shipping damage. We will email you a prepaid shipping label to return the damaged flask and will send out a replacement upon receipt.

Rattling bottles: The rattle you hear is a small metal disc that sits between the double wall of your bottle that aids in the vacuum insulation process. Sometimes the disc becomes dislodged and you can hear a noise.  This will not affect the insulation of your bottle. If you can live with it, so can we. However, if it is an annoyance, we will exchange it for a new bottle.

*NOTE: Any damage to the bottle, other than minor scratching, would void the lifetime warranty. While our bottles are made to be as strong as possible, denting them can compromise the insulation. So please try your best to take care of your bottle!
