The Hydraulic™ Dry Pack is a super heavy duty dry pack ideal for portaging and canyon runs. Whether in the airport, running a river or out in the field, the EVA foam and air mesh harness will deliver comfort and airflow for small or large loads. The removable harness attaches to compatible Hydraulic™ Dry Bags with lightweight but very robust aluminum buckles.


  • High tensile strength and abrasion resistance make Hydraulics perfect for whitewater and overland adventures


  • The fabric is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure

Best Use

  • Canyoneering, Base Camp, Paddle Sports, Overland


  • 600D TPU laminated heavy duty waterproof fabric
  • UV resistant PVC free fabric withstands cold temperatures
  • Waist strap (35L) or hip belt (65-120L) help support the load when the pack is filled.
  • Non-wicking TPU roll-top closure with an innovative interlocking profile that is secure and waterproof
  • Welded construction for permanently sealed seams
  • Welded durable TPU lash patches for carrying gear or securing the pack.
  • 7075-T6 anodized aluminum buckles (Field Repair Buckles on shoulder straps and hipbelt) are robust and fail safe
  • Fully adjustable back length and height adjustable sternum straps
  • Low-profile attachment points to reduce snagging when the harness is not attached
  • The harness system is easy to put on and take off. Screen-printed diagrams on the welded patch show the herringbone pin/harness removal steps
  • 35L size has a 25mm webbing waist belt
  • Features the patent-pending 1in | 25mm Field Repair Buckle with stainless steel pins



  • Waterproof? The fabric is more than adequately waterproof (10,000 mm hydrostatic head) – just avoid submersion, as water can seep through the roll-top closure of any dry bag.

  • Be used for canyoneering? It can – if you have realistic expectations. Canyoneering packs are often used as friction devices when sliding down rock faces: in this kind of environment any pack will wear through after a couple of seasons.

  • 35L waist strap be replaced with the 65-130L hipbelt? Unfortunately not. The 35L waist strap has vertical attachment points, the 65-130L hipbelt has horizontal attachment points.

  • Be used as a portage pack when carrying a canoe? Possibly. If you carry your canoe over your shoulders using the yoke, a Hydraulic Drypack may be a little too tall.
