Product Description
Big Hydration. Premium Insulation. Fewer Refills.
When you want more water on hand without constantly refilling, the Oasis 1.5L Insulated Drink Bottle delivers.
Its generous 1.5L capacity is combined with triple-wall vacuum insulation to keep drinks cold for up to 18 hours or hot for up to 10 hours. Inside, a ceramic-coated lining creates a barrier between your drink and the stainless steel, helping avoid the metallic taste some people experience with standard stainless steel bottles.
Add a one-touch sipper straw and built-in carry handle and you've got a large-capacity bottle designed for easy everyday hydration.
Why We Chose Oasis
There are plenty of premium insulated bottles on the market, but a bigger brand name doesn't necessarily mean you're getting more of the features that matter to you.
The Oasis 1.5L combines triple-wall vacuum insulation, a ceramic-coated interior and a full 1.5L capacity.
That's where it stands apart from comparable large Stanley and YETI bottles, which use double-wall vacuum insulation with stainless steel interiors.
And at $49, Oasis gives you these premium construction features at a significantly lower price than comparable large-capacity bottles from the big-name brands.
Ceramic-Lined for a Cleaner Drinking Experience
Ever noticed a metallic taste when drinking water from a stainless steel bottle?
The Oasis 1.5L features a ceramic-coated interior, creating a barrier between your drink and the stainless steel beneath.
You still get the durability and insulating benefits of stainless steel, but with a ceramic drinking surface designed to help your water taste like water.
Triple-Wall Vacuum Insulation
Oasis uses triple-wall vacuum insulation, compared with the double-wall vacuum construction used in the comparable Stanley and YETI bottles.
The Oasis 1.5L is designed to keep drinks cold for up to 18 hours or hot for up to 10 hours, helping maintain the temperature of your drink throughout the day.
1.5 Litres = Fewer Refills
A bigger bottle means more water within reach.
With a full 1.5L capacity, Oasis gives you more capacity than the comparable Stanley 1.5 QT and YETI 1.4L bottles.
It's ideal for long workdays, training, road trips, outdoor adventures or simply keeping more cold water beside you throughout the day.
Easy to Drink. Easy to Carry.
A large bottle shouldn't be awkward to use.
The one-touch sipper straw lets you drink directly from the Oasis without unscrewing a cap or pouring into a separate cup, while the built-in handle makes its larger capacity easier to carry.
