Our One Life…One Bottle^™ mantra caused us to search for a bottle and cap material that did not require funky unknown composition enamel coatings, did not leach any chemicals or toxins, and is typically comprised of recycled material. With several aerospace engineers on our staff, it is not surprising that we were quickly drawn to stainless steel, but with over 150 varieties available, we needed to find a composition that not only met the requirements above but was cost effective and manufacturable. We settled on #304 stainless (also known as 18/8) for our bottles and caps; a composition that has long been used in the food service and medical industries and is rated as a sanitary, non-leaching material. In addition, our stainless steel is not only 100% recyclable, but stainless steel in general is typically comprised of approximately 60% recycled material…a stark contrast to petroleum based plastic water bottles which are clogging our landfills.

#304 or 18/8 refers to the composition of the metal - 18% chromium and 8% nickel. Lesser grades of stainless such as #201 or #301 substitute a lower cost metal, manganese, and we did not feel that composition was as well suited to the needs of our customers.

As a result of using this high grade stainless steel our bottles do not require the coatings so often seen in competing aluminum bottles, a fact that has been very important to our customers. In fact many have found it a bit disturbing that the leading aluminum bottle manufacturer will not even disclose the chemical make-up of their so called "oven enamel"…it kind of makes one wonder what they are trying to hide and if there are long term health ramifications to exposure to this material.

We are also happy to report that our bottles are much more durable than aluminum or plastic bottles…and we are willing to put our money where our mouths are with a limited life time warranty. No other bottle manufacturer is willing to offer a warranty like this because their bottles do not stand the test of time despite the grandiose claims on their web sites.

In the end, we believe that we have created the ultimate water bottle…one that will last for years and one that we hope people will use and reuse instead of drinking bottled water made from disposable plastic water bottles that are a critical threat to our environment.

We strongly believe in the One Life…One Bottle^™ mantra and we hope you will too!
