The BOULDER vacuum insulated water bottle is our flagship bottle that will keep your drinks hot or cold all day long. Made from premium 18/8 stainless steel, it features our signature TriMax® triple insulation and keeps drinks cold up to 90 hours and hot up to 18 hours.

The Reflecta lid is insulated and lined with stainless steel, enhancing temperature retention and preventing drinks from ever touching plastic. The dual-opening lid is easy to grip, has a wide mouth for easy filling, and a soft silicone spout for a comfortable drinking experience. The lid is securely attached to a sturdy carrying strap, so you always know where it is, and the leakproof seal keeps your drinks in the bottle - where they belong.

The BOULDER stainless steel water bottle also includes a removable strainer for tea, fruit, and ice cubes. The fitted silicone bumper adds protection against everyday drops. Plus, choosing a reusable water bottle cuts down on single-use plastic consumption. There’s nothing the BOULDER doesn’t offer!

Keep the BOULDER in your car cup holder or toss it into a tote and bring it to the gym, on the trails, or to work to stay healthily hydrated through the day.

Awesome Bottle!

This is the best bottle I have ever had the opportunity to use. Bought fie my husband as a gift. Very well made. Keeps liquids cold as advertised. I love the silicone attachment for the lid that also serves as a carrying handle! It even has silicone foe the mouth piece so you're not cracking teeth on metal on scraping your lips. Works so well I just ordered the blue one for me and can't wait to receive it! I only wish they had PURPLE! Great product!

Great quality bottle

Excellent water bottle. I have purchased multiple bottles from this company and I have been pleased every time. I love the lid design, never any metallic taste in your beverage, and it does not transfer flavor.

I Own Six of These

These are simply the best I’ve found. Did an un-scientific test with a similar bottle from another well known brand, by putting same sized large ice cube in them (and using a Boulder lid on both). The ice lasted much longer in the Boulder than the other one (wasn’t even close). Just wish they came in more colors!

Ice doesn't last long

I live in Arizona, it's hot right now. I bought this one because I wanted my ice to last at least half the day. Sadly I'm lucky if it has ice by noon and my day starts at 6am . The lid is where the heat gets in. It isn't insulated well.

Better Than YETI

5th ECO purchase. Couldn't be happier. Cold beverage in hot weather and hotter car. No BPA'S. Easily cleaned wide mouth, silicone covered drinking spout. They thought of everything. I've purchased hydroflask, before they were cool, and YETI'S. These rival hydros with more and much better options and prices. Blow YETI out the water.
