Compact hydration, full capability

The Source M.C. 3L Ultimate Low Profile Hydration System is designed to ride close to your body, reducing bounce during movement while keeping hydration within easy reach. The included XL filling handle makes refills straightforward, and the UTA Rapid Refill Adapter speeds top-ups in the field. This setup is FILBE compatible and works with common hydration systems, making it a versatile choice for demanding missions or day-to-day training.

Designed for real-world use

Engineered to fit US Marine Corps FILBE gear, the bladder remains comfortable under load while offering reliable access to water. The system embraces two valve designs with performance oriented design: the Helix Valve and the Hi-Flow Storm-Valve for smooth operation and reduced spills.

• Helix Valve with a rounded mouth design that requires no fixed orientation and a built-in bio-net style shut-off to prevent spills during transport.
• Hi-Flow Storm-Valve is a no-bite push-pull valve with an integrated shut-off, and it disassembles easily for cleaning.
• Angled Valve rotates 360 degrees for perfect valve/mouth orientation, with a shorter tube to minimize excess tubing and bouncing on the chest.
• Dirt shield valve cover protects the mouthpiece from dirt and debris, while the Cool Weave Cover Tube insulates and blocks UV light.

Practical benefits at a glance

• Low-profile design that stays out of the way under packs and outer gear, suitable for active wear and tactical kits.
• Versatile compatibility with Helix and Storm Valve ecosystems, enabling flexible configurations.
• Integrated temperature protection and UV shielding help keep fluids cooler and clearer on sunny days.
• Secure fastening and easy maintenance with disassembly-friendly components for quick cleaning between sessions.
