What is the interior glass finish made of?
Purist technology transforms silicon dioxide, one of the most fundamental elements on earth, into a flawless interior glass finish.

How does Purist technology affect taste?
Purist emerged from our conviction that taste should never be compromised. Whether it’s a metallic tinge or a hint of last week’s coffee, your Purist bottle won’t retain any unwanted tastes.

How long will it last?

When cared for properly, the Purist technology will remain intact for the life of the bottle. Because the interior glass finish essentially becomes part of the bottle, it won’t delaminate, chip, or peel off.

How long will my Purist bottle retain temperatures?

Purist bottles keep drinks hot for 12 hours and cold for 24 hours.

What materials are the bottles made of?
The outer wall is made from durable 304 stainless steel, while the inner wall is made from surgical-grade, 316 stainless steel.

How do I care for my Purist bottle?

We recommend washing all Purist bottles and tops by hand. Do not scrub interior with abrasive brush or material. To clean, simply rinse with warm water and mild detergent or use a soft cloth as needed.




How long does processing and handling take?

Processing and handling takes 2-3 days. After that time, your order will ship and you will receive a shipping confirmation email with tracking details.

Where do Purist products ship from?

All purist products ship out of our facility in Morgan Hill, CA.
