Here, we cover the Top 5 Questions we get asked about the Greens Steel Water Bottle, so you can start your hydrated life with confidence:

5. How Long DO Greens Steel'S Bottles Keep Water Cold FOR?

Q:  I spend a lot of time driving, and I want to make sure my drink won’t get hot if I leave the bottle in my car’s cup holder. How long will it keep my water chilled?

A:  All day... and then some!  Every Greens Steel bottle is created to keep drinks cold for over 12 hours.

This incredible temperature retention is possible thanks to the double-wall vacuum insulation.

(Which is the most advanced form of thermal insulation in the entire water bottle industry!)

In a nutshell, Greens Steel’s double-wall vacuum insulated water bottles are constructed with two distinct stainless steel walls with a small amount of air sandwiched between them.

This air pocket does a great job of insulating your bottle from outside temperatures. How? In short, it forces heat on the outside to be transferred through it before reaching your beverage.

In physics, thermal conductivity occurs when heat moves from a hot area to a cold area. This eventually results in equilibrium.

But with double-wall vacuum insulation, heat has to travel first through one layer of stainless steel, then through a layer of air, then through another layer of stainless steel before it actually penetrates. This takes an extremely long time!

With this construction method, Greens Steel’s water bottles keep your beverage cold all day long.

4. Do TheSE BOTTLES Ever Leak?

Q:  I go to school and I love hiking on the weekends, which means my water bottle always gets tossed in my backpack. But I need to have a completely leak-proof bottle that won’t spill anything on my textbooks! Does this bottle ever leak, even if I forget to put it in upright?

A:  Nope!  Our water bottles are designed to be 100% leak proof, thanks to a special construction design in the top cap. Nothing is worse than a leaky bottle ruining the contents of your bag, so we made sure this design feature was absolutely perfect for your peace of mind.

Simply twist the cap into place until it grabs down on the special sealing thread.

Then rest assured, knowing your water bottle will be securely sealed for your entire adventure, trek around campus, or workday!

No more worrying about your water or drink spilling in your backpack! Each water bottle’s body is also guaranteed leak-proof for years to come, due to its durable exterior and rust-resistant steel that won’t chip, dent or crack.

3. WHAT’S THIS 18/8 STAINLESS STEEL all about?

Q:  I see you mentioned 18/8 Stainless Steel in the water bottle’s description… Why is this so special?

A:  It’s the absolute best material in the world for portable drinkware!  We use this hard-working metal in all our Greens Steel drinkware, as its quality and functionality refuses to compromise.

Also called 304-grade stainless steel, 18/8 stainless steel is comprised of 18% chromium and 8% nickel (which is where its name comes from).

This resulting alloy is supremely resistant to corrosion and oxidation. That means your stainless steel bottle will last for years to come without the risk of rust or degradation, even if it’s exposed to water or air. That means you can leave water sitting in your bottle all the time without worrying about the inside wearing out!

As an added bonus, 18/8 stainless steel is very easy to clean. So, maintaining your Greens Steel Water Bottle for longevity and hygiene is simple.


Q:  I’m super careful to make sure my family isn’t exposed to toxic BPA, but I know it’s still included in lots of kitchenware containers these days. Does Greens Steel use any BPA in the production of your products?  

A:  Absolutely Not!  We’ve got young families too, so we understand how critical it is to look out for the health of our littlest loved ones. BPA has never, and will never, see the inside of our Greens Steel factory.

In case you haven’t heard of this nasty substance yet, here’s an important heads-up about this dangerous stuff... Unfortunately, some competitor’s food service containers are still made with BPA, despite the health risks.

BPA stands for bisphenol-A.

It’s a synthetic chemical that has been used in the construction of plastics and other food service items for years.

Alarmingly, the FDA recently found that even low levels of BPA have been linked to certain types of breast cancers and other negative health effects. Because of this, BPA is now considered toxic and should be avoided at all costs.

Fortunately, Greens Steel products don’t contain any BPA whatsoever, even in the few plastic pieces or painted coatings we use. Your family (and ours!) will always be sipping safely.

1. Do These Bottles Really Come With a Lifetime Guarantee?

I’m pretty tough on my gear, and I’ve come to expect my daily water bottles to only last about a year before I need to get a new one! Do you really offer a lifetime guarantee, even if my bottle has some battlescars from my adventures?

A:  Yes! We stand behind the quality, toughness and longevity of our bottles with such confidence that every single one comes with our no-questions-asked Lifetime Guarantee.
