Great pack - Eberlestock Fac Track Backpack

Thus far, the pack has been used to transport gear and clothing for military trips, not for any real arduous work. For a three day pack, the size is perfect. I fit in clothes for three days (three shirts and pants, socks, Skivvies, etc.) PT gear to include shoes, combat boots, hygiene kit, and in the radio pouch I stashed my laptop computer. The outer pouches were large enough to fit all the extras I might need, with room to spare. I had to purchase the larger pack straps so the bag would fit my frame, but it is comfortable to wear for a 15Km walk, with the above load and a couple 100oz bladders. Only negatives I have regarding the pack are caused by me, not issues which one may incur if using the pack for it's intended use. The pack when stuffed as described above almost didn't fit inside the overhead bin of an airplane, but after some readjusting I crammed it in, but had I had any delicate gear in the outside pouches it may have gotten broken. Going through TSA, getting the top open to remove the laptop, wasn't a problem, putting it back was a difficult process because of the various splits inside the radio pouch area which caused it to snag. Again, I'm using it for more trivial uses than it's intent, but it works and works well.
