Coming this September is Fidlock’s very first attempt at a hydration bladder. Of course, it wouldn’t be a Fidlock product without the use of magnets somewhere; here, three magnetic bars that run along the full width of the Hermetic Hydration Bladder’s wide opening snap shut, sealing the watery contents inside very rapidly for leak-free riding and spill-free refills.

Fidlock’s magnetic closure systems are successfully employed on everything from cageless water bottles, to convertible full face helmets, to tool boxes; now, they’re sealing the deal on an all-new hydration bladder.

The Fidlock Hermetic Hydration Bladder will be available in 1.5 L and 2.5 L capacity options, both with tall, narrow dimensions suited to riding packs, as opposed to hip-packs. While Fidlock’s line of Hermetic dry bags are designed to keep water out, the Hermetic Hydration Bladder is designed to keep water in, relying on the same magnetic seal technology.

Nothing can go wrong, they say.

All three magnetic bars close automatically and seal the contents, so even if you drop the hydration bladder mid-refill, it wont spill a drop as the magnets will spontaneously snap back together to seal the contents. Fidlock tell us the high-quality materials are perfectly coordinated and reliably welded to ensure that not a single drop of water drop can get outside the bladder. An extra snap buckle sits external to the main closure to ensure the whole package is entirely leak-proof.

The bladder itself is made of a BPA-free TPU for neutral-tasting water, and comes with the drinking tube. The opening runs almost the full width of the hydration bladder to help make both refill and cleaning easier.

Pricing & Availability

The Fidlock Hermetic Hydration Bladder will be available this September in two sizes; 1.5 L and 2.5 L, both retailing at 59,99 €.

Has anyone explained to Fidlock what a hermetic seal actually does?
