Built for those who like their carry-on with a little extra character, the Frequent Flyer is ready for takeoff. Sized at exactly 3.4 ounces, it meets TSA liquid limits, making it easy to slip into your bag without a second thought. Each piece is crafted from 22-gauge solid copper and finished with a high-shine polish, while the interior is lined with molten, lead-free tin using a closely guarded process that speaks to the brand’s old-world approach. The result is a flask that feels substantial in hand and purpose-built for travel, with just enough capacity to take the edge off mid-flight or wherever you land next.
