High quaility hydration pack. 12 litre capacity hydration bladder. This is perfect as either a running rucksack or cycling rucksack as well as hiking and walking
Internally it has two full-length compartments, one for the water hydration bladder and one for you to securely store items such as a wallet, tools, puncture repair kit, energy bars, gloves, etc. An additional small, interior zippered compartment lets you securely store small items, such as keys, while an exterior mesh pocket allows you to stow items for easy access, such as maps or your phone. Chest and waist straps enable you to fit the backpack securely, keeping it in place
Specially designed to fit together, the backpack has hooks that allow the included water bladder to clip into place so that the bladder stays upright and secure. This allows all of the water to be used as well as reduces potential damage to the bladder. A built-in hole for the hydration bladder's hose near the shoulder area of the backpack allows you to easily access the water and stay hydrated on the road.
Included with the water hydration bladder is a 1 metre long hose with an easy-to-use on/off tap at the mouth end. The hose can quickly be attached or removed by screwing it into the water bladder, and is designed to work perfectly with the BTR water hydration bladder cleaning kit.
