Salomon Sense Pro 10 Set Womens Hydration Backpack Salomon’s Sense Pro 10 Set Womens Hydration Backpack is an excellent way to transport everything needed for long trail runs, with the soft mesh and stretch panel construction ensuring a close, comfortable fit. It provides 10 litres of capacity spread across a multitude of pockets front and rear, making it simple to organise the day’s kit so it is all easily accessible. The front of the pack has two stretch pockets that hold the included 500ml soft flasks so that they can be drunk from without taking them out, and at the back there is a system for stowing walking poles away when they aren’t needed. As any weight is spread across both the front and back of the pack, it is better balanced than a normal rucksack or bumbag and Salomon’s Quick Link sternum strap adds further stability whilst still allowing easy breathing.
