I bought the Large Timbuk2 Command after finding that the&nbsp;<a data-hook="product-link-linked" class="a-link-normal" href="/Timbuk2-Commute-2012-Laptop-Messenger-Bag/dp/B0080B834Q/ref=cm_cr_arp_d_rvw_txt?ie=UTF8">Timbuk2 Commute 2012 Laptop Messenger Bag</a>&nbsp;was slightly too small for my laptop. The Command fits my 15" laptop and its oversized battery with room to spare. The protective foam around the laptop pouch feels thin but I haven't had any problems with it yet. The main compartment is large with just the right amount of organization; there's a sleeve for files, a couple of pouches, and then a large space to use however you want. The four pouches in the front are all useful, especially the side access pouch which you can access without opening the flap. There's velcro attachment for the flap if you want it but it also comes with covers which prevent the velcro from making any noise. The metallic hooks used to keep the flap closed may not be as secure as a traditional buckle but they've kept the flap closed for me so far and look better doing it. I haven't ascertained the purpose of the large plastic buckle on the shoulder strap, but that aside the shoulder strap feels sturdy even when the bag is fully loaded. Overall I'm very pleased with the Timbuk2 Command.
