Most polo shirts fail at the collar. The standard knitted version - soft, small, collapsing around the neck - works at the beach but falls apart the moment you reach for tailored trousers or a jacket. The Oslo takes a different approach. A substantial ribbed collar built on a proper collar stand, the same construction logic as a dress shirt.
Short sleeve or long sleeve. Under a jacket or on its own. The Oslo works across both. The long sleeve version extends the range into cooler evenings and shoulder seasons where a short sleeve would feel out of place.
