For a messenger bag there is quite a lot of space inside the CorePack Fly. I think the main reason for this is because the laptop compartment is actually separated from the rest of the bag. This way you don’t have to worry about anything damaging your laptop, it’s simply out of the way. I decided to load this bag up, as far as gear goes we have the Lenovo ThinkPad Edge 13-inch laptop, Cooler Master NotePal ErgoStand, a book I’m currently reading, Seagate FreeAgent Go 320GB hard drive, card reader, Corsair Flash Padlock 8GB drive, iPhone, iPod, Kodak EasyShare M420 digital camera, power strip, headphones, iPhone cable, USB cable and a few pens. Everything fit easily inside of the CorePack Fly.
The front 3 pockets on the CorePack Fly are perfect for small devices like phones and digital camera. The far left pocket actually has an opening in it for headphone to stick out. This way if you are in bad weather you can still listen to music or be on the phone without possibly damaging your device. As we said the laptop compartment is all by itself so our laptop went in there last.
With the laptop fully loaded you have 2 options when it comes to carrying it. If you want to attach the shoulder strap you can by lifting a metal clip on each side of the bag and attaching it. I like that the clips are hidden in case you want to use the handle, which is concealed in a pocket on top of the bag. Using either the shoulder strap or the handle is very comfortable, it all depends on your preference.
This is an airport checkpoint friendly bag which means you will not have to remove your laptop from the bag when going through security. All you will have to do is un Velcro the laptop compartment from the back and unfold it as shown in the photo below. It is really easy to do and takes about 5 seconds. Sure beats having to take your laptop out every time you go through security!
