Used only once on a trail. I cleaned it and stored it, as I had no further opportunities to use it. I'm selling it because it doesn't look like I'll be using it. From the official website: For trail running and challenging hikes, you need to replenish water and food, and sometimes you need gear. With the Norvan 7, you can comfortably carry what you need. Multiple adjusters provide the best fit, and you can store a lightweight shell, food, water, as well as a helmet and high-performance tools needed in the mountains. The lightweight and sturdy stretch mesh pack material securely wraps the contents and minimizes movement inside. Multiple front pockets allow easy access while moving, and also include holders for two flasks. The top and back dump pockets are sized to accommodate larger gear.
