The HoodieCarrier is rather clean. It feels like a baby wrap and has a hood.
The PhysioCarrier is more massive, it has a ventilation pocket on the baby's back (which opens and closes) and a mirror to see baby carried on the back.
Both are physiological, 4 seasons and offer a front, side and back carrying from birth (with the booster pack and headrest) at 20kg.
Take the one you like the most;)
