Overview
The Rockagator Hydric Series 40L Waterproof Backpack in red (RedRock), part number RKGHDC40RDRK, is a 40-liter waterproof pack for overlanding and camping. It carries a universal fit rating rather than a fit for one vehicle. It is the 2018 refresh of the original Hydric model.
The refresh keeps the strengths of the original and adds changes that make the pack stronger and easier to use. Its 40 liters offer ample room for bulky loads. It is 100% quick-submersion waterproof, so gear inside stays dry during a quick dunking. Straps and welded seams carry a warranty against defects.
Hikers and overlanders who strap bulky gear to the outside can use the top cinch strap with its UTX clip to compress the upper pack and secure whatever sits on top. Two hypalon tether points sit on either side above the mesh pockets, and parallel daisy-chain straps on the back offer more anchor points for bungees and carabiners. Those daisy-chain straps were carried over from the original design.

- 100% quick-submersion waterproof construction

Load and attachment checks
Before a trip, look at the load as a whole rather than one bag at a time. A pack that is packed evenly and held firm against the back rides more comfortably, and it puts less strain on the anchor points. Compress soft items first, then add firmer gear, and tighten the cinch strap only after the load is settled.
Welded seams hold up well when they are kept clean, but grit and sharp contact can wear the surface over time. Rinse the pack after exposure to mud or salt, and store it loosely rather than squeezed under heavy items. Periodic checks of the seams and the strap hardware will catch small problems before they grow.

The warranty applies to the straps and welded seams, not the whole pack.
