After trying a couple different brands, including Platypus, this is the reservoir I'm gonna drink from.
The valve shut-off is much more secure than my Platypus, which dumped 2 liters all over the back of my Jeep because it came unlocked. The cap is easier to work than the zip on the Platypus, and the piece below the cap provides an excellent filling handle. Detachable hose is easy to get on and off, and the bite valve works flawlessly. The drying arms are a nice feature, as is the center baffle, which really does keep the water from sloshing around, even on dynamic, rocky trail runs.
Nice to see innovation that works.
