The Overwatch Portrait Border Season Rewards is based on a players competitive play ranking. Portrait Frame/Borders are visible to other players during lobby loading times and also when viewing your account profile.

Currently players can earn Overwatch Portrait Borders from simply leveling.
While the more exclusive and limited edition Portrait Border Season Rewards will be awarded to players at the end of the season. This is a purely cosmetic Overwatch Season Rewards meaning it will not create any unfair advantage. It will however make your profile look unique and respectable from others.
