It might seem like the soprano ukulele is already an exceptionally portable instrument, but Kala have taken that idea one step further. They have made it even more compact by shrinking the width of the body (to an inch and a half at the widest). It does seem to defeat the object making a travel tenor ukulele but I'm sure they're are people who want to reduce the width but don't mind the length (if you find a double-entendre on the site let me know and I'll whip it out immediately).
The uke has a solid spruce top making it very much a serious ukulele (not just a gimmick).
There's also the humorous (or tacky depending on your point of view) compass on the headstock.
