FIDLOCK

HERMETIC Hydration Reservoir

What Our Gearhead® Experts Are Saying:

"I’ve used this reservoir on long rides and hikes, and it’s seriously one of the easiest to live with. No awkward folding or clamping—just fill it, let the magnets snap shut, and go. It seals tight every time, and cleaning it after a dusty trail run or hot ride is super quick. Totally leakproof and taste-free—exactly what I want from a hydration system."

Hydration shouldn’t be complicated, and the Fidlock HERMETIC Hydration Reservoir makes sure it isn’t. Built with Fidlock’s patented magnetic self-sealing technology, this innovative bladder closes automatically—no folding, zipping, or fiddling required. Just fill it, snap it shut, and get moving.

Three rows of integrated magnets seal hermetically for total leakproof protection, while the large opening makes refilling and cleaning fast and simple. The BPA-free TPU construction ensures your water stays fresh and taste-free, even in warm conditions. Available in both a 1.5L version for hip packs and a 2.5L version for backpacks, it’s perfectly tailored to your setup. With the included drinking tube and Fidlock’s SNAP closure preventing accidental openings, this reservoir is as smart and reliable as it gets—hydration done right, the Fidlock way.
