Familiarity: I've put it through the wringer
This is my favorite hydration pack when I switch between packs that don't have their own system. Also, if I want to fill it up with ice for a hot day, this is the bag I reach for. The top opening is large and easy to open and close, making cleaning a breeze as well. The bit valve works well and I appreciate the screw lock and cover for when I need to toss it in the car or set it on the ground.
For backpacking, I have a DIY gravity filter built around a Sawyer, and this is my clean bag after the filter. The hose quick connect does not leak when the hose is removed, making filling easy through this connection.
