High5 Reusable Gel Flask

The HIGH5 Refillable Gel Flask is a reusable energy gel flask designed to make fuelling during running, cycling, triathlons, and endurance training more convenient and sustainable. Simply fill the flask with your favourite energy gel at home, customise your carbohydrate intake, and dilute with water to achieve your preferred consistency. Clear measurement markings show both gel volume and carbohydrate content, making it easy to monitor your nutrition throughout your workout. Holding the equivalent of just over 13 standard HIGH5 40g energy gels, this lightweight, recyclable* soft flask helps reduce single-use packaging while providing reliable, on-the-go fuelling. After use, simply wash with warm soapy water and reuse time and time again. Filled flasks can also be stored in the fridge for up to six weeks after opening, making preparation for your next training session or race quick and easy.
