The Poseidon Messenger Bag will easily fit under most airplane seats; it's 11.5" high, 14.5" long and 2.75" thick. Empty, the bag weighs in at a featherweight 1 lb., 11 oz.
On the inside, the Poseidon is all business. The front flap of the bag is held in place by two monstrous strips of Velcro and a pair of side-release buckles so it doesn't fly open when you're whizzing through the streets on your bike or skateboard.
Under that flap are three layers of pockets of various sizes for holding papers and pens. There's a strap with a link on the end of it for holding onto keys. As you move back closer to the computer compartment, there's another zippered pocket that's perfect for holding cables and chargers.
Now we get to the meat of the Poseidon -- the computer compartment. It's big enough to hold up to a 13" MacBook Pro, and well-padded on both sides. The bottom of the compartment holds an inch-thick modular padded insert that's removable if you're using a 13" MacBook Pro and stays there if the bag is holding an 11" MacBook Air. That's not all you can put in the computer compartment, though. It has enough room to hold an iPad or two, and there are more pockets.
Finally, there's the long strap for carrying the messenger bag like ... well, a bicycle messenger. That means you can sling it around to your back or side while the strap goes over the opposite side shoulder. The pad on the strap is one of the thickest I've encountered on a computer bag. To adjust the strap, there's a big cam buckle that loosens to give you more or less strap, then clamps down to hold the strap in place.
Did I mention that the Poseidon has pockets? I'm almost wondering if the designers at ECBC were going for a record or something, 'cause this bag is crazy with pockets. Those big Velcro pads and the buckles that hold the case flap down are excellent for keeping the bag securely closed, and the water repellent coating on the Kodra exterior will make sure that your electronics remain dry even in pouring rain.
The construction of the Poseidon is excellent. The sewing, use of heavy duty zippers, and the hardware are all top-notch, and Velcro patches are scattered throughout to keep some of the smaller pockets closed.
Seriously, I usually use a good sized SwissGear backpack to carry all of my stuff, and I found that I can put all of that gear and more into the Poseidon.
