In the main chamber of the backpack there is a separate place for liquids containers. There is also a tube hole to lead out the drink tube for beverages ( the liquids container does not come complete with backpack). Additionally in the main chamber there is a small zipper pocket. There are two pockets in front. The top closed pocket is used for accessories. The bottom pocket is flexible and allows you to put in a waterproof jacket. The sides flex pockets are used for bottles and rod keeping, additionally there are adjustment straps for better attachment. The Active backpack is equipped with comfortable, adjustment suspenders, waist belt and chest strap. A great allrounder.
