An ultra-light carry-on friendly 100ml flask with a bottle opener on the base

Coming in at a carry-on friendly 100ml, our take on the classic hip flask is an ideal travel companion, yet generous enough for a few good measures. A machined cylindrical design allows for a wide mouth for zero waste filling and smoother drinking than the traditional flat flask. We've also designed in a knurled grip cap that doubles up as a handy half measure, a dual seal and a useful bottle opener on the base.

With the world’s highest strength-to-weight ratio of any metal, Titanium is typically used in aerospace and motorsport where strength and weight matter most. Our matte titanium is blasted with 80-micron fused alumina particles at 100 m/s to create a fine, uniform smooth finish. Soft to the touch and noticeably darker than our machined titanium, it feels unexpectedly substantial in the hand while bringing unmatched resilience to our everyday tools.
