Unlike a flat pocket flask, the Wingback is cylindrical — narrow enough to slip into a jacket pocket or bag, and sized at 100ml to clear most international carry-on restrictions. The dual-seal cap prevents leaks, and the knurled lid gives a reliable grip when removing it one-handed.

316 stainless steel doesn't impart flavor, doesn't corrode, and is dishwasher safe. The base unscrews with any split ring — one is included — and doubles as a bottle opener.
