I've been using the eBags Professional Slim as my every day carry (EDC) backpack for about a year and a half. It is a well thought-out, high-quality and great value backpack that is great for techies and urban professionals. I've not had any problems with it the 1.5 years that I've been using it for work and I would recommend it to others. However, I am planning to change to another backpack soon for reasons not related to the backpack itself.
