May I suggest that you go to the source and visit the RedOxx Web site? www.redoxx.com

They are easy to work with via e-mail or telephone. There is also much information of the site posted by both customers and professional viewers including the One Bag guy.

All RedOxx bags are tough, but no one can promise they will work in all situations without being checked. I decided not to go with the Air Boss because it is just too big for me.

I e-mailed with the RedOxx folks and also talked to them via telephone and came up with a different one of their bags (Sun Chaser) that works for me, meets my needs and if the envy of my travel companions.
