How much does the GPR50 hydration pack weigh?

The GPR50 weighs approximately 2.5 pounds (1.13 kg) when empty. When the 50oz reservoir is full, the total weight is about 5.75 pounds (2.6 kg).

How do I know that it will integrate into my particular helmet?

The GPR50 is designed to work with most full-face and open-face helmets. The magnetic helmet connection and flexible boom straw require no permanent modification. Installation is fast and reversible, and the on-helmet mount fits the vast majority of popular helmet brands and models.

How long does it take to charge and how long does a full battery last?

A full charge takes about 2 hours using the included USB-C cable. Once fully charged, the battery powers approximately 10 complete dispense-and-refill cycles, which equals around 500oz of water delivered.

Can I use electrolytes or other sports drinks in it?

Using anything other than clean water can void the warranty, as sports drinks and additives may cause buildup or damage to the internal pump and tubing. For optimal performance and long-term reliability, we highly recommend sticking to water only.

What is the warranty? What’s protected? For how long?

The GPR50 comes with a 1-year limited warranty covering manufacturer defects in materials and workmanship. It does not cover misuse, modifications, or damage caused by using non-water fluids in the system.

How do I know the current battery level?

There are two ways to check battery level: Press the button near the LED indicator at the top of the pack, or view it in the FluidLogic mobile app.

How do I clean and store it?

We recommend occasionally flushing the system with clean water. For deeper cleaning, run a water-vinegar solution through the line and rinse thoroughly. Before storing, be sure to dry the reservoir completely, and store the pack in a cool, dry place with the bladder open to air out.

Does it keep my water cool or cold?

The GPR50 is not an insulated system, but the low-profile design and location against your back help keep water relatively cool during rides. For best results, fill with chilled water or add ice cubes.

Does it have any additional storage for other items?

Yes—the GPR50 includes a small external zip pocket for essentials like keys, snacks, or a phone. It also features external bungee straps that provide flexible storage for a light jacket or extra layers, making it easy to carry what you need without adding bulk.
