The Active Root 150ml Gel Flask is a simple, mess free way to carry your fuel exactly how you like it. Designed to work perfectly with Active Root Gel Mix or Energy Gels mixed with water, it gives you full control over texture, flow, and intake during training or racing.
About 150ml Active Root Gel Flask
Lightweight and durable, this soft flask slots neatly into belts, vests, and packs without bouncing around. It holds up to 4 servings of Gel Mix or 3 Energy Gels, allowing you to tailor your carb intake to suit your session. By adding more or less water, you can adjust the viscosity to match your preference, whether you like it thicker and concentrated or smoother and easier to sip.
The flip up cap and wide opening make filling and cleaning quick and hassle free. When empty, the flask collapses down to save space, making it ideal for long runs, rides, or races where every gram counts. Made from recycled materials and free from PVC, BPA, and phthalates, it is built with performance and sustainability in mind.
At just 18g and measuring 70 x 148mm, this 150ml flask is compact, practical, and ready for race day.
How does it work
The 150ml capacity allows you to pre mix multiple servings of fuel into one reusable flask. By combining Gel Mix powder or Energy Gels with water, you create a smooth, adjustable consistency that can be sipped gradually. This supports little and often fuelling, which is easier on the stomach and more effective for maintaining energy levels over time.
The soft TPU body compresses as you drink, reducing bulk and movement. The 26mm opening makes filling straightforward, while the secure flip cap helps prevent leaks during high intensity efforts. It is a simple system that gives you complete control over how and when you fuel.
