Works as advertised. i really like it - Matador Hydrolite Filtration Backpack

I've had this bag for a couple of months and generally been very happy with it. I've primarily used it as a day bag when traveling.

Good:
* Super packable. Easy to throw into another pack an. Fit nicely under the seat in front of me on a plane
* Hydration pack works really well. I haven't tried removing the filter, but even with it inline water flow was good
* Holds a good amount - I found no problems using it as a day pack and throwing a book and a few day items. Even with the bladder full
* Back Panel Providers some airflow -The back panel definitely provides a noticeable amount airflow on my back. Not as much a pack with a rigid frame, but I wouldn't expect that
* Hose pocket on the shoulder strap works great
* comfortable enough for a full day of use.

Room for improvement
* Back mesh isn't durable - I got a small tear in the back mesh while adjusting the hose to the hydration pack. I had a good amount of weight in the bag and was holding it awkardly, but I was a bit disappointed
* The chest strap is pretty short - I'm not large person, but I found the chest strap to be too short and ultimately unusable.
* The hydration hose is a little bit too long - This is pretty minor and I' sure I could fix it, but the hose is just awkwardly long
* The valve on the back panel was somewhat uncomfortable
* I wish there were another mechanism for closing the top of the bag to allow for some quicker access that rolling/unrolling and double clipping each side
