Frequently Asked Questions

What beverages can I craft with the Adventure Flask?
The Adventure Flask is your all-in-one beverage multi-tool. Craft fresh pour-over coffee, steep cold brew (12+ hours), brew loose-leaf tea, shake craft cocktails, decant wine, infuse fruit water, and of course — use it as your everyday hydration bottle. From the campground to the kitchen counter, one flask does it all.
What's included with my Adventure Flask?
Every Adventure Flask comes with: the 32oz Insulated Flask body, Pour-Over Lid, Steel Filter Basket (150-micron for cold brew & tea), Thermal Core, Craft Connector (for pour-over, cocktails & decanting), and a Pup Cup — everything you need to start crafting right out of the box.
How long does it keep drinks hot & cold?
Double-wall vacuum insulation keeps beverages cold for up to 18 hours and hot for up to 8 hours. Whether it's ice-cold water on a summer hike or piping hot coffee on a winter morning — the AF delivers all day long.
What materials is it made from?
Built to last. The flask body is crafted from 18/8 medical-grade stainless steel with an electropolished interior that resists stains and odors. Lids and caps are BPA-free polypropylene #5, and the Cocktail Strainer uses durable, BPA-free Tritan™. Zero bisphenols — just clean, safe sipping.
Can I use it for carbonated beverages?
Yes! The Adventure Flask handles carbonated beverages with no issues. Just be mindful when opening — pressure can build up, so open the lid slowly to avoid any fizzy surprises.
Do you offer free shipping?
Absolutely! All Adventure Flasks ship free within the US. Orders typically ship within 1–2 business days, so you'll be crafting beverages in no time.
What awards has the Adventure Flask won?
The Adventure Flask has been recognized with some of the world's most prestigious design honors: the 2020 Red Dot Design Award, the 2021 iF Design Award (beating nearly 10,000 entries from 52 countries), and was featured on Shark Tank. It's also been named "Best Tailgating Gear" by Outside Magazine. This isn't just a bottle — it's an award-winning innovation.
What's your warranty & return policy?
We stand behind the Adventure Flask with the Hibear Guarantee. Not satisfied? We offer hassle-free 60-day returns. We want you to love your AF as much as we do. View our full return & warranty policy →
Is it easy to clean?
Incredibly easy. Simply unscrew the Pour-Over Lid and you'll reveal the extra-wide mouth opening — wide enough to fit your hand right inside. A quick wipe with a sponge is all it takes. No bottle brush required. The electropolished stainless steel interior resists stains and odors, and the whole flask is dishwasher safe. For deeper cleaning, soak with a vinegar-water solution or use cleaning tablets like Bottle Bright.

Product Info, Use & Care

What beverages can I make with my All-Day Adventure Flask?

The system is designed for ultimate versatility. You can craft pour-over coffee, cold brew, and loose-leaf tea; shake or stir cocktails; decant and aerate wine; and create fruit or spirit infusions. Of course, it also excels as a premium insulated bottle for hot or cold water, beer, or any other beverage you can dream of.

Is my Hibear AF dishwasher safe?

For the best long-term care and to protect the flask's powder-coat finish, we recommend hand washing the main body. For convenience, the lid, cap, and Hibear® Craft Connector™ components are all durable and top-rack dishwasher safe. Just remember that subjecting your flask's body to the high heat of a dishwasher may lead to wear and tear on the finish over time.

How long do drinks stay cold or hot?

The double-wall vacuum insulation will keep beverages cold for up to 18 hours and hot for up to 8 hours. When using the Thermal Core accessory, it will keep a drink chilled for 8 hours without any ice dilution.

Can my Hibear go in the freezer?

No. Placing the vacuum-insulated flask in the freezer can damage the vacuum seal and compromise its insulation performance. For ice-cold drinks, we recommend adding ice directly to the flask or using the Thermal Core accessory.

Can my AF hold carbonated beverages or be used as a growler?

Yes, absolutely. The flask is designed to handle carbonated beverages like beer, seltzer, or soda without any issues, making it a great option for use as a growler.

How do I safely remove stubborn stains from the inside?

For tough stains, you have a few safe and effective options. First, try soaking the inside with a solution of 1 part white distilled vinegar to 5 parts warm water for about 10 minutes. Alternatively, a paste of baking soda and water can be used with a soft brush to gently scrub the stains. For a deep clean, specialty cleaning tablets like Bottle Bright also work very well.

My AF has white patches on the powder coat. Is this normal?

Yes, this can occasionally happen after washing with hard water. These spots are simply harmless mineral deposits. To remove them, carefully pour boiling water over the affected areas, and they should disappear.

What is my Hibear made of?

We use only premium, health-safe materials. The flask body is crafted from 18/8 medical-grade stainless steel. The lids and cap are made from BPA-free polypropylene #5, and the Cocktail Strainer uses durable, BPA-free Tritan™. No materials in the flask contain bisphenols (like BPA or BPS).

What is the airspeed velocity of an unladen swallow?

To answer that, one must first know if they are speaking of an African or a European swallow.

Ordering & Shipping

What is your shipping policy?

We ship orders Monday through Friday. A tracking link will be sent to your email as soon as your order ships. We offer flat-rate shipping in the US and also ship internationally to Canada, the UK, France, Germany, Australia, and Japan. Expedited shipping options are available at checkout.

How do I place a request for a custom project for my company?

We'd love to work with you. Please visit our B2B page and fill out the form. We can add a logo to an existing flask or work with you to create a fully custom bottle design.

Can I order additional or replacement silicone sleeves?

Yes! You can customize the look of your bottle with different colored sleeves. The current available colors are Its On-Range (orange), Night Hike (black), California Gold, and Pour Decision (mauve).

Returns & Warranty

What is your return and exchange policy?

We offer free returns or exchanges within 60 days of receiving your order for new, unused items. You can return your product for store credit, a different product, or a refund to the original payment method. Please note that discounted/final sale items cannot be returned. For more details or to start a return, please visit our Returns & Exchanges page.

What if I have a warranty issue with my bottle?

We stand behind our product. If you believe you have a warranty issue with the functionality of your bottle, we want to know about it and help you out as soon as possible. Please visit our Returns & Exchanges page and use the Warranty Claim form to submit your issue.

Who would you recommend this bottle for?

If you dislike travel, trees, tents, mountaintop vistas, surfing, skiing, running far, climbing high, sunsets, and puppies, then this probably isn't for you. But if you love to celebrate the summit, relax by the campfire, enjoy making a perfect pour-over, or just want a ridiculously solid everyday water bottle... 10/10 would recommend.
