Jacto XP-12 3 gallon Backpack Sprayer

The Jacto XP-12 is a manual, 3-gallon backpack sprayer designed for weed control and crop protection: 
The UV-resistant, blue tank has airflow grooves and is curved to fit the operator's back.
The pump is an internal piston pump mounted inside the tank, so any leaks go into the tank instead of down your pants.  
The straps are deluxe, quick-adjust, wide straps with thick shoulder pads.
Comes standard with an adjustable cone nozzle.
The wand is a durable, chemical, and corrosion-resistant stainless steel with a heavy-duty metal trigger.
Other features include hydraulic agitation, a molded-in carry handle, accurate volume markings in gallons and liters, and a wide opening with a strainer.
The XP-12 is designed to be easy to pump, with only 8 pumps required to reach 45 PSI. It also has a Santoprene piston seal and is designed for a minimum 1000-hour service life. 
Designed to be comfortable, robust, and efficient.
