I had a Fatboy Versapack, but my wife thought it looked too much like a purse. I needed something bigger anyway and was looking at the larger Versapacks. I decided to go with this instead and I'm glad I did. More room, more comfortable for long carries and it doesn't look anything like a purse. Very convenient for discreet concealed carry, firearm can be easily accessed while pack is on your back (right hand, only). The Versapacks have a ton of little pockets, sleeves and such all over the place, the Monsoon has some, but not nearly as many. I ended up buying a few Maxpedition accessories to add some external pockets for little things.
Pros: Comfortable, roomy, great looks.
Cons: Just be aware, not as many pockets a Versapacks
