This bag is an exact replica of the Maxpedition Colossus Versipack only without the Maxpedition label. Look up the price and specifications of the "real deal" on the web and you'll realize what a great deal this bag is. The original is priced at well over $100...
It serves well as go anywhere "bugout bag" or just for hauling your gear around. My wife refers to it as my "man-purse". I couldn't do without it!
If you want to expand its hauling capacity as I did, then you can get some side pouches for it. They are also exact replicas of the Maxpedition originals:
Molle Water Bottle Medic Pouch
Molle Medic First Aid Pouch Bag
The water bottle pouch is a perfect fit for a 1 litre Nalgene bottle.
Everything about this gear is top quality - it's built to take lots of use and abuse. I liked them so much, I bought a complete three part set in Coyote Brown, Digital ACU and Black. Enjoy!
