FIDLOCK

HERMETIC Hydration Reservoir

What Our Gearhead® Experts Are Saying:

"I swapped my old reservoir for this Fidlock version, and I’ll never go back. It seals itself instantly—no clamps, no leaks—and the magnetic closure is unbelievably reliable. It’s easy to clean, easy to fill, and fits perfectly in both hip packs and hydration packs. Just a smarter system all around."

Fidlock’s HERMETIC Hydration Reservoir redefines hydration design with a patented magnetic self-sealing system that eliminates traditional closures. Three integrated magnetic rows automatically align to form a 100% watertight seal, keeping your pack—and gear—bone dry even on punishing rides. The additional SNAP closure ensures the reservoir remains securely closed, preventing accidental openings during high-output efforts or bumpy terrain.

Available in 1.5L and 2.5L capacities, the bladder’s wide mouth simplifies filling and cleaning, while its BPA-free, taste-neutral TPU construction ensures clean, pure water with every sip. The included hydration tube connects easily, integrating seamlessly into both hip and backpack systems.

Engineered for riders and athletes who demand simplicity and performance, the HERMETIC Hydration Reservoir embodies Fidlock’s signature magnetic-mechanical innovation. It’s hydration made intuitive—lightweight, secure, and built for the flow of the ride.
