Original Hydration Tank Bag
Patented hydration gear with a ballistic-grade nylon shell, dual thermal insulation, and a custom 3.2-liter reservoir. Designed to keep water ice-cold for over 8 hours in extreme temperatures, supporting responsible hydration for riders and other users spending long days in the elements.
OffRoad Hydration Tank Bag (Black)
This is the ThirstyRock Hydration Tank Bag OffRoad. With two rows of anchor points, loop velcro and tie-down cord, this allows the rider to add their own gear accessories to the top of the hydration tank bag while riding. Get all the same high performance and versatility as our Original hydration tank bag.
TRH 3.2 Pack
The TRH 3.2 Pack takes the proven, game-changing features of the ThirstyRock Hydration Tank Bag and engineers them into a trimmed-down 9x9x5-inch hydration pack. Designed for hikers and motorcycle riders who already have a favorite backpack, tank bag, saddlebag, or tail bag, it provides personal ice-water hydration without replacing existing gear. Slide it inside or mount it on compatible luggage, extend the 3-foot insulated hose, and connect the retractable reel and connector grip to the exterior to turn regular gear into a hydration system.
A rider’s problem. A rider-built answer.
Coast Guard veteran and retired peace officer Dan Dougherty conceived the system after riding through the punishing heat around Moab. Dan and Irene turned the idea into working prototypes, tested what failed, and built the hydration gear they could not find anywhere else.

“First ride with their tank bag today, Salt Lake City to Phoenix, with much of the ride being 80+, and the last 1.5 hours above 100. The bag worked flawlessly, and having nice cold water readily available was a life saver. I’ll be ordering a second one to strap on my tourpak when we’re traveling 2-up! (FB Review)”
“Just finished 3 day ride around eastern Nevada. Most of the ride was in +100 degree days. Your bag worked flawlessly and prevented me from getting overheated. Excellent! Thank you very much.”
“I do long distance rallies and Iron butt rides through all kinds of weather including extreme heat. I love my thirsty rock. I mount it to the top of my left pannier and it's easy to fill and keeps water cold. I also especially like the on/off valve. I remove the bite valve and just use the on/off valve so much easier than any other hydration pack I've used (and I've used a few).”
