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.

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.

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.

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.

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.

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.

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.

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).

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

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.
