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.

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.

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).

What is your return and exchange policy?

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.
