I am preparing for a trip in February that necessitates very light packing. We have a strict weight limit for the flight from Chile to Antarctica (!) of 55 lbs. Now, 55 lbs might sound like a fair allowance, but this is a photography tour, so we will all be carrying camera equipment, laptops and the necessary peripherals, and cold weather gear. I got the lightest weight rolling camera bag I could find, loaded it with the necessities, and that weighs in at just shy of 25 lbs. So far, so good.

In my effort to pack light and smart, I am sticking with taking almost nothing clothing-wise that isn't gear. It won't be my most fashionable trip, but warm and dry is the name of the game. I'll have some time in Patagonia after the Antarctic portion of the trip, so hiking shoes and multiple light layers will be the strategy.

In my efforts to pack light, I'm considering a new bag. Most of our luggage is sturdy and a bit on the heavier side. I'm thinking specifically of a rolling duffel. The bag I already own that comes closest to working for this trip is a 30" rolling bag that weighs 9 lbs. I'd love to go a little smaller and as much lighter as possible, while still having wheels. Maybe 26" or so? And under 7 lbs would be great.

Anybody have any suggestions? I've been poking around a bit online and some things look good in theory but it's hard to truly assess size, usability and quality from an online picture.
