Nantucket Vaqueta Leather Laptop Sling Bag / Backpackstar rating 5Rebecca SwannDecember 13, 20095 stars only because there aren't 10 . I LOVE this bag. Asa musician, I am often running from job to job with different music for each. AHH, the file compartments. It says 5 " deep but I got SO MUCH MORE in it yesterday. Thick music books, water bottle, spare picclo, stand light, etc., etc. and even put the handle of my flute case around one of the steel rings. My MP3 player fit in a small pouch on the side. LOVE the beige lining since I have a lousy dome light in my car. You can SEE to the bottom of everything. Hands free using the backpack formation and probably loded with thirty lbs but it did not feel heavy. Very well balanced. Zippers everywhere so nothing falls out. That has always been the bane of my existance: something falling out or dropping something that did not fit in a bag. Another plus: My 15.4 laptop has an oversized battery, bringing the width to about 12 and one half inches, but leather is forgiving. I did have to put the cooler plate in one of the music slots, but I would not be carrying that much music and a laptop at the same time anyway. I am guessing that with all the compartments stuffed, this bag stretches to about six inches in depth, yet the 12 inch width keeps it looking slim and professional. I may buy another at some point just for my computer. In the meantime, I couldn't be happier. This brand is such great quality and particularly this bag with the metal rings rather thatn flaps which can tear. Service time was unbelievable. Doing business is such a pleasure with LeatherPaks. Thanks and Merry Christmas. I WILL be back!
