I like the removal of the 1" extender -- I've never used that feature on mine -- and a lighter weight cloth sounds nice. After all, I don't check the bag, only carry it on, so it doesn't need to be bulletproof.
The travel kit, however, is awesome. With the kit I can I fit my boots, boot dryers, all my clothes, my laptop, a reader, all my toiletries, stick a helmet on the outside and the Käydä is the one and only bag I need. Then my ski bag only has skis and poles (+ avy gear when necessary) which is ideal. By now I'm kind of used to the airlines deciding that they don't want my skis to accompany me, but would rather have them catch up a day later!
I see on the Kartta there are two clips on the back. Can the travel kit be attached to it?
