An interesting solution to the posture problem. Intelliskin posture undershirts behave like Kinesio tape (and were actually born out of demand for a tape replacement that lasted for more than a couple days) by providing tactile feedback to postural muscles. That’s the theory, anyway, and it seems to work. While we can’t confirm or refute the tech behind Intelliskin, we can speak to its results. Bottom line: these shirts will haul you into shape, whether you like it or not.
