ドロメダリー ハイドレーションバッグ

Rolled this thing down to almost nothing in my pack and barely noticed the weight. Held enough water for a full day of scrambling without sloshing around.

Filled this up for a long day hike and barely noticed the weight. The way it collapses down flat after emptying is honestly the best part, since it takes up almost nothing in my pack.

Took this on a two-week road trip and it packed down to almost nothing in my duffel once empty — that collapsibility alone sold me. Medium-large capacity held enough water for a full day of hiking without weighing me down.
