Thick Coat is a Boom Boom Amigo ability: his heavier coat lets him take more damage before he goes down. It keeps your scout alive when a fight goes loud.
Boom Boom can soak up more hits before you need to revive him. That matters when he is running between bodies with Fetch, Boy during a firefight.
A quiet but useful upgrade. Fewer revives means less time exposed yourself.
