The Arkel Commuter bag is great for commuting. Imagine that! The commuter has a large main compartment, with a well padded laptop "nest" suspended from the top, and lots of other easy access pockets inside and out to store smaller items. The bag is well styled with a nice urban look so that if you are carrying it into your office or a class you will look good. When off the bike there is an integrated flap to cover Arkel's great cam lock attachment system and a padded shoulder strap. Other features include an integrated rain cover and reflective piping.
