I just got my Think Tank Airport Helipack and the quality of the materials are bar none. I am a Professional Photographer along with Videographer so I needed something that I can carry both my drone and camera with lenses. I was looking for a backpack light enough that I can travel with by plane and also hiking for destination shoots. So far I am able to fit 1 P3, 3 Batteries, battery charger, 1 iPad Air, 1 15" MacBook Pro, 12 props, Sony A7s, 2 canon lenses, 1 Sony lens and various accessories and it isn't bad on the shoulders. Now I know the price tag isn't for everyone it's the perfect bag for any professional not doing this as a profession. I built my own hard case seahorse that worked well for just my drone but I'd rather consolidate all of the bags I travel with.
