Great bag. Really like the way it carries - both the handle and strap are on the bag at the same time. The handle is in the middle, so it's comfortable for regular handling. The strap is towards the side, so it rides comfortably flat against your side. Because it rides so easily, it easy to use both your hands to open the cargo hatch or door to the plane. No need to set it down in a puddle. I like all the compartments, but don't yet remember where everything is kept. But still easier to zip and look, than dig through the bottom of my old flight bag. A normal iPad fits easily into the end compartment, and a mini iPad fits easily in sideways. A navigation plotter (yes I still carry one just in case) is almost to big for the end flap, but goes right in between the bag sections. I divided the middle section in half with the velcroed shelf. In the top half, accessible by the top opening flap, I keep the POH. In the bottom half, accessible by zipping the case open like a clam-shell, I carry all those other flight manuals that come with our new avionics. I leave my headsets in the airplane. When I bought this bag, I thought I might later purchase an additional section for carrying overnight supplies. But no longer. The bag is a great size as it is, and a small duffle would suffice for the rest. Maybe my old flight bag. Zippers seem good quality; not worried about them failing.

Great bag. Love it and carry it every day. Used many and this is the best design. Costly but worth it.

Solid flight bag
The bag is well made and durable. Flight bags take a beating and this one is well designed. I like the many pockets which hold all I need for my daily flights.

best traveling under the seat bag ever!!
UPDATE: I have traveled a few times with this and love everything about it except the one side pocket, the velcro doesn't really keep it closed that well. Other than that it is rock solid and vastly superior to anything like it. ORIGINAL REVIEW: I'm a traveling AV Tech not a pilot and I love this bag!!!!!! No more lumpy backpacks there must be 16-18 compartments in there. And you can adjust them. My dog can fit in there, she is 3 lb chihuahua. 13 in MacBook Pro fits perfectly, any larger than that is not going to work. i use the middle section for my jacket, rear compartment for the computer, front in between space for paper files. many compartments for gizmos, pens, stuff. Glasses fit in center front section perfectly without the case. everything I had in my lumpy backpack fit and this is lighter and not lumpy at all.

Great quality bag
Very well built. Heavier than most other bags of this type. Limited space for larger items but plenty of room for small stuff.

The last flight bag you'll buy.
It costs a little more, but it's worth it. By far the best flight bag I've owned.

Nice quality - not lightweight.
The bad is actually heavier than I thought, which becomes a pain to carry with your computer, etc. Top zipper is awkward because of the way it curves to the side pockets. It IS compact, so easy to store. Love the pockets. VERY sturdy, so it will probably last a lifetime.

A bag that lasts.
I've been running this bag for a few years, about half the that time being at the airlines and the other half back to corporate. It's a really awesome durable modular bag, I've beat the heck out of the thing the last few years and it's held up great. It's seen thousands of miles and plenty of adverse weather. Everything has it's own space with this bag which is nice as well. My only recommendation is to buy the B4 swift ECHO instead. Mainly because it has the J hook handle (for any of you purdy neat or luggage works guys out there), and it also has an adjustable pocket for the water bottle. You don't think it's that big of a deal but when you need to unzip the side of the bottle holder just to barely squeeze in a regular size water/ drink, it's kind of a pain. Even fully extended it's not big enough to really hold a regular sized coffee cup. For these 2 reasons and the fact that there's almost no difference ($7 total) in price between this B4 and the B4 ECHO, it's worth getting the echo version. That being said this is still hands down one of the best bags to have as a professional pilot.
