The fuel belt Helium Ergo hydration belt is ideal for endurance runners who want 16 ounces of hands-free hydration and storage in a lightweight belt. The breathable Helium hex foam material has air channels that allow Airflow, wicking away sweat for comfort during long runs or in warm weather. The belt comes with two 8-ounce bottles mounted in angled quick-access holsters, allowing runners to remove and replace them with one hand without breaking stride. Bottles are designed in a body-contouring, ergonomic shape and are BPA-free and dishwasher-safe. The belt is ideal for both training runs and races, with detachable Micro race locks to securely hold a race bib without the need for safety pins. Reflective accents provide extra visibility when running on cloudy days or for those early morning or late evening runs. The Removable, water-resistant storage pouch keeps cell phones and other small valuables protected from sweat or rain. The pouch is sized to fit standard smart phones. The belt is easily adjustable during a run, with a custom closure and different versions for men and women to ensure the best fit for every athlete. The fuel belt Helium Ergo hydration belt weighs only 350 grams, including the unfilled bottles and storage pouch.
