Is the bladder leakproof?

The bladder is constructed from heavy-gauge PEVA with reinforced seams designed to resist punctures and prevent leaks. An internal auto-shutoff valve also prevents leaking when the hose is disconnected from the bladder.

How does the hose connect and disconnect?

The hose uses a fast-disconnect system ? simply insert and lock it into place. To remove, press the push-button quick release for a clean, drip-free detachment. The auto-shutoff valve prevents any leaking when the hose is detached.

Can I fill the bladder with ice?

Yes. The oversized wide-mouth screw cap with integrated handle is large enough to accommodate ice cubes, making it easy to keep your water cold on warm-weather outings. The wide opening also makes filling from any water source quick and convenient.

How do I clean the 4L hydration bladder?

The extra-large screw cap provides full access to the interior, making cleaning straightforward. Rinse with warm water after each use. For a deeper clean, use a long brush to scrub the interior and run a brush through the hose and bite valve.
