This bag is my daily companion in the office. It has a padded compartment for laptop / tablet, where more easily fit A4 documents. Another big compartment is for small items (or rain pants ....) available here however you can in large documents reach the limits. The assembly on the bicycle is simple. Deductions's for the lack of coverage of the fixing (had its predecessor, yet, you have to remove cumbersome now) and the lack of ability to stow the strap. Here the last ounce of application understanding lacking in product development.
