Salomon's ADVANCED SKIN 12 GRADIENT is a hydration waistcoat that fits the body perfectly. This ever-popular and ever-efficient model comes in a range of sizes, including this 12-litre version.

Quickly forgotten during the race, this waistcoat is a highly functional piece of equipment that runners love. Breathable and stretchy, it has a streamlined design that keeps the essentials close to hand. As well as a host of cleverly designed pockets, it comes with everything you need to keep from getting dehydrated, including a water bag suspension system, 2-litre water bag compatibility and two 500 ml softflasks.

It has a high-quality back-carrying system and is ultra-lightweight. In this way, the athlete concentrates solely on running.
