Exohiker by Berkeley Bionics

The construction of ExoHiker™ was completed in February 2005. The ExoHiker™ was designed for carrying heavy loads during long missions. It weights 31 lbf including the power unit, batteries and on-board computer. The Payload is 150 lbf while the wearer feels no load. Noise is virtually imperceptible and can be compared to an office printer.

Mission Duration without small pack-mounted solar panel: 42 miles for a pound of battery (Lithium Polymer) at the average speed 2.5 mph. With a small solar panel, its mission time will be unlimited. Due to an unprecedented actuation and power delivery technology, an 80 W-hour battery which weighs 1.2 pounds is sufficient to power this exoskeleton to carry 150 pound of load for 21 hours while the wearer feels no load on her/his shoulder.

The interface is a small hand-held LCD display. The legs are retractable which they've called "easy-stow™". The whole unit can be quickly released in an emergency.
