Effect You trace a finger along the wave patterns on the barding, granting your companion a swim Speed of 30 feet for 10 minutes.

Even if the companion doesn't have the mount special ability, it can still Swim while being ridden.
Traits
An item with this trait can be worn by an animal companion or similar creature. A companion can have up to two items invested.
A character can invest only 10 magical items that have the invested trait. None of the magical effects of the item apply if the character hasn't invested it, nor can it be activated, though the character still gains any normal benefits from wearing the physical item (like a hat keeping rain off their head).
This magic comes from the primal tradition, connecting to the natural world and instinct. Anything with this trait is magical. A creature with this trait is primarily constituted of or has a strong connection to primal magic.
