Source Hydration WXP Reservoir Upgrade Kit

The internal baffle keeps the reservoir flat even as you drink, preventing the 'sloshing' sensation and the sagging bulge common in traditional bladders. This helps the reservoir sit more comfortably against your back and keeps your pack's center of gravity stable.

Yes, the included refill adapter allows you to fill the reservoir directly through the drinking tube. This is a significant time-saver on long hikes or rides when you need to top off at a water station without unpacking your gear.

Yes, the Glass-Like PE liner creates a smooth, non-porous surface that prevents water from absorbing the taste of the plastic material. It is significantly more effective than standard polyethylene bladders at keeping your water tasting fresh.

Not at all. It is a non-bite valve, meaning you simply pull the cap to open it and push it back to close, providing a high flow of water without needing to bite down. It also includes a protective cover to keep the mouthpiece clean from trail debris.

The Grunge-Guard antimicrobial technology inhibits bacterial growth, meaning you don't need to clean it as frequently as standard bladders. When you do need to clean it, the wide opening allows for easy access, and the materials are designed to resist buildup over time.
