The removable harness on our Hydraulic™ Dry Pack makes portaging a whole lot easier – whether on the river, in the airport or out in the field. The Hydraulic™ Dry Pack is a great option for carrying large volumes of gear when a traditional backpack just isn’t suitable.

The Hydraulic™ harness is an open construction of EVA foam and air mesh, allowing plenty of air flow and rapid drying without sacrificing any comfort. The Harness attaches to compatible Hydraulic™ Dry Bags with a series of aluminium buckles as tough as the bags themselves.


  • Quick drying EVA foam straps and air mesh construction
  • Aluminium buckles are robust and fail safe
  • Fully adjustable back length and height adjustable sternum straps
  • Low-profile attachment points to reduce snagging when harness is not attached
  • Easy to put on and take off
  • 600D TPU laminated heavy duty waterproof fabric
  • Non-wicking TPU roll top closure with innovative interlocking profile that is secure and waterproof
  • Welded construction for permanently sealed seams
  • Durable UV resistant PVC-free fabric withstands cold temperatures
  • High performance abrasion resistant fabric
  • Oval base to resist rolling
  • Features a replaceable buckle with stainless steel pins
  • Lash loops for secure attachment
