A flask... But a flask made to last.
No leaks. Less replacing. Happier planet.

A flask is a flask, some people think. But we try to think about things differently. And to leave less trace, wherever possible. That’s why our clear flask is tougher, and longer-lasting, than most. With no-leak tech: a soft, high-flow bite valve that auto-seals after each sip, eliminating drips.

TECHNOLOGIES:

Safer. Smarter.
Made from 100% TPU, the flask is also BPA- and PFC-free, which is (much) better for the planet. It’s also safe for the top rack of your dishwasher (up to 60°C) after a particular muddy scramble.
