I've got three of these, and honestly I can't imagine why they are so inexpensive. They are HUGE, have a great amount of space and utility. I have one that I used to carry all of my things for work and school when I would have to work from campus, and now I use it just for night school. I have another I use as a gig bag of sorts for my musical peripherals and anything else I can think of. The third is our travel/amusement park/fun activity bag. They've held up great over the years and we've put them through their paces!
Good value. I purchase them in multiples several times a year for our students who are in need. Both the recipients and school administrators indicate these packs meet their needs.
This was my 3rd Fatboy. I still have my 1st Fatboy, it has Heavier straps with elastic shock protection - on shoulder straps, same basic design pockets and heavy duty zipper pullers. Now you know the difference a decade makes. I like Fatboy to carry groceries on my bike and an all-round roomy and tough backpack. Handy on hospital visits - better than light luggage. The large spring-hook is great for my red-blinking bicycle light mount.The black color stays clean/new looking longer. A great price, functional and long-lasting.
