Tried and true backpacking reservoir - Platypus Hoser Reservoir

Tried the Osprey designed Hydraform Reservoir in 2012 (see my review) but nothing beats the basic function, easy of use and durability of the Hoser reservoirs I have used over 5 years. Note: adaptable to the new Sawyer Squeeze Filter with a "tornado adapter".
