In the 2015 Tour de San Luis, four different jerseys were awarded. For the general classification, calculated by adding each cyclist's finishing times on each stage, the leader received an orange jersey. This classification was considered the most important of the 2015 Tour de San Luis, and the winner of the classification was considered the winner of the race. Additionally, there was a sprints classification, which awarded a green jersey. In the sprints classification, cyclists received points for finishing in the top 3 at intermediate sprint points during each stage, on a 3–2–1 scale.
There was also a mountains classification, the leadership of which was marked by a red jersey. In the mountains classification, points were won by reaching the top of a climb before other cyclists. Each climb was categorised as either first or third-category, with more points available for the higher-categorised climbs. For first-category climbs, points were awarded on a scale of 10 points for first across the climb, second place earned 8 points, third 6, fourth 4, fifth 2 and sixth 1. Third-category climbs awarded points to the top three riders only; 3 points for first across the climb, second place earned 2 points, third place earned 1 point.
The fourth jersey represented the young rider classification, marked by a white jersey. This was decided the same way as the general classification, but only riders born after 1 January 1993 were eligible to be ranked in the classification. Lastly, there was a classification for teams, in which the times of the best three cyclists per team on each stage were added together; the leading team at the end of the race was the team with the lowest total time.
