Input:
This hydration pack works very well. Plenty of pockets for storing ALOT of things, and some well though out pouches and Velcro to hold things. It can also carry a rolled up jacket which is nice, and has both a stomach and chest strap to secure the bag to your body well. I am only giving this 4 stars because the color I received is not a darker navy blue as the picture indicated, but rather a light blue that I am not a big fan of. But the bag works great and exactly as I wanted it to.
