It is plausible that this is geared more towards a weekend getaway rather than a long trip via airline. I like my original bag, what they now call the Snow Roller Pro 127L. Its construction is robust, it is spacious (two pairs of skis along with extras), and I love how it rolls up for storage. The only gripe I have is that the detachable handle will often come unhooked on one side (one side has quick-release clips and the other doesn't), but that is often mitigated by making sure the bag is rolled tightly. The light version also rolls up, but it doesn't have that some "bombproof" feeling as the original.
I carry one bag, the Kulkea Käydä Travel backpack. There is
another thread where it has been discussed at length, but suffice to say I think it is
nearly perfect. I can fit all of my ski clothes, my street clothes, my boots, my toiletries, my laptop, and then attach my helmet to the outside. Because it is a backpack-style, and not the traditional boot-bag, it fits easily in overheads on all but the smallest of planes. I will stipulate, however, that I am a longtime "one bag travel" advocate. I've learned to travel light and fast!
