I try to keep business travel as light, and fast as I can. The Henty Wingman is a bag that matches my style perfectly.
The Henty Wingman fits two or three sport coats, or two suits, in its garment pocket. There are also pockets for shoes, clothes and a waterproof section for your toiletries. I have no trouble packing for 3-4 days in this bag, and using it as my sole carry on. Once the bag is fully packed, it rolls up to something not much larger than a yoga mat.
Jackets, if carefully packed, come out pretty much as nice and crease free as they did from the dry cleaner. I suggest folding your shirts into a compressing packing envelope, and not hanging them with the jackets. Packing shirts in the garment bag does leave them with some light creases. Nothing hanging out in the bathroom while you shower won't fix, however.
The outside storage pocket fits my Kindle, iPad or even Macbook Air. I keep my chargers in there too, and I do not need to carry any other bags with me on short trips!
I've managed as much as a two week trip, living out of this bag, but it involved a lot of laundry at hotels. It is certainly light, easy to pack and the first bag I look for when I've got to run out of town. Like right now!
