Description
The Naked Running Flask 500ml is an ultralight soft flask manufactured by Hydrapak, engineered to deliver world-class hydration performance for runners. Weighing just 30g, this collapsible flask features a low-profile design with a 28mm cap and high-flow bite valve, optimized for use with running vests and belts. The flask includes printed volume markings in both milliliters and ounces for easy tracking of fluid consumption.
Made from durable yet flexible thermoplastic polyurethane (TPU), the flask is 100% free from BPA, PVC, and phthalates, ensuring safe hydration from recyclable materials. The innovative collapsible design allows the flask to shrink as you consume liquids, progressively reducing its mass and volume to minimize bounce and improve comfort during your run. The high-flow bite valve provides quick, easy access to hydration without breaking stride.
This flask is ideal for trail runners, ultramarathon athletes, and endurance enthusiasts who demand reliable, lightweight hydration solutions. Designed to fit seamlessly into Naked running vests and compatible with standard vest pockets, it's perfect for long training runs, races, and outdoor adventures where every gram matters. The flask comes backed by Hydrapak's Beyond Lifetime Guarantee, and care is simple with dishwasher-safe construction (top rack) or hand washing with warm water and mild detergent.
