Why you'll love it
RUGGED BUILD
The shatter-resistant body and silicone bumper are built to handle travel and outdoor use. It’s made to take falls better than a standard flask.
HINGED CAP
The silicone cap stays attached on its hinge, so it’s hard to lose when you're filling or pouring. It’s a simple detail that matters in the field.
MEASURING MARKS
Built-in graduations make it easy to measure what you’re pouring. Useful when you want more control than a standard plain flask gives you.
