The 14" Little Stick is travel sized. At 14'' (34cm), It is shorter, more rigid and, can be used one-handed for neck, arm, and calf muscles.

The 'Little Stick' is promoted for kids, but I find it perfect to stick in a suitcase - even a carry-on - for trips. It is an ideal size for sore calves after lots of walking.
