This 2L hydration reservoir delivers reliable fluid intake for endurance athletes engaged in high-intensity pursuits like cycling and distance running. The TPU construction with PVC tubing and silicone nozzle provides durability across temperatures from -20°C to 50°C. A 100cm drinking tube enables convenient hydration access whether the bladder sits in your pack or on your back, allowing controlled sipping during sustained effort when large gulps aren't practical. Compact dimensions (36×17cm) and lightweight design (200g) minimise pack burden. The green bladder integrates seamlessly into training routines, supporting consistent hydration without interrupting your performance.
