Full Description

Ultra runner Xavier Thévenard was wearing the Marathoner vest when he won the 2015 UTMB, the legendary trail race around Mont Blanc. This vest doesn't need much more of an introduction - it is quite simply the best hydration solution on the market. The design has been developed and optimised by Camelbak over the years, and integrates their patented Antidote® water reservoir. It can hold two litres of water, making it ideal for long runs of two hours or more. The mesh panels keep it light and breathable, and the snug, stable fit reduces movement and maximises comfort. It has enough capacity for an extra water bottle, a thin outer layer, gloves, hat, nutrition, phone, and keys. Camelbak undertake rigorous testing of their products, ensuring that the reservoir won't bust or leak. In fact you can even freeze it for those hot days when you want to sip on ice cool water. The reservoir's Quick Link™ System makes it easy to remove for cleaning, so you can use it with a hiking backpack too.
