The cap seals so tight I can turn it upside down without a single drop, and the wide mouth makes pouring way easier than my old flask. It's heavier than I expected but that solid feel is exactly why I trust it in a bag.

Tossed this in my hiking pack for a weekend trip and it didn't leak a drop, even bouncing around in the side pocket. The cap twists off smoothly and the whole thing feels solid without being too heavy to carry.

The cap seals tight enough that I can toss this in a backpack and not worry about leaks. It's heavier than a cheap flask, but that's exactly why it feels secure in hand.
