The Y 07 Hydration Pac is a compact backpack for bikers and other outdoor enthusiasts as well. However, considering the utility, this Carbonado offering can hold more than just a bladder of water. It has an overall storage capacity of 7-litres with provisional storage of 2-litres for the water bladder (to be bought separately).
The Exterior
As seen in the above image, the Y 07 has a hard shell at the front with a leather-like material. The backpack can be detached from the straps as the four-way adjustable harness comes with quick-release clips. Speaking of the straps, Carbonado has equipped the pack with a wavy structured foam for both the straps and the back. The brand claims that it provides comfort and allows airflow. Then, the Y 07 also gets reflective strips on the shoulders and the bottom. Not to mention, the two reflective strips also hold the bladder tube in place.
The Interior
As mentioned earlier, the Carbonado Y 07 Hydration Pac comes with three major compartments. The first is the hard-shell unit with five smaller pockets, followed by a larger space for the Quench pack, and a third located at the back. The latter is fairly large and can be used for storing slightly slimmer items. Carbonado has also provided an opening for earphone wires but you’ll need to cut that piece on your own.

Speaking of the bladder, dubbed Quench, it’s made of EVA. Carbonado claims it to be safe for drinking water and pressure resistant. It’s a 2.5-litre pack and can be attached to the bag using the internal Velcro straps of the Y 07. The Quench pack gets a large mouth/opening to fill/refill it as well as add ice cubes if needed. And at the bottom, the bladder gets a small tubular inlet to attach the water pipe in the threading. The latter comes with a small washer which should secure the pipe properly in the opening. The other end of this pipe (opening to sip water) is wrapped in a rubber mouthpiece which too gets a plastic cover for added protection from dirt. The rubber unit gets a small cut in between for the water to be sucked in. All you have to do is pull the hose up, bite the rubber and sip water, and push it back to lock. It’s covered by a camo-coloured cloth all around.
