Some products are good because they are well designed. That is, they are functional, good looking, and give no cause to question the taste or decision-making-ability of the user. Better products also come with a great warranty. The best products, have the aforementioned, but come with a lifetime warranty, or a continuing guarantee of performance, and excellent customer service. 

Bosca's "Partner's Brief" is among the best of products, and if you need a lawyer bag, it should more than do the job.
