Hydrapak ブラダー

The opening on the valve is wider than my old bladder, so filling it at a creek is way less of a hassle, and the cap seals tight enough that I don’t worry about leaks in my pack. It’s held up fine through two rocky scrambles so far, and I like that it doesn’t add much weight to my setup.

Took this on an overnight backpacking trip and even after tossing my pack around, not a single leak. The fact that it rolls up so small when empty is a game-changer for packing light.

Filled it up before a long day hike and the whole setup stayed leak-free the entire time. The bite valve delivers a steady flow without much effort, which is exactly what I want when I'm moving fast. Works perfectly with my existing pack, so no complaints here.
