A mesh long sleeve top for the gym or running gives you sun protection and ventilation without the weight of a traditional athletic top. The long sleeves cover your arms while the mesh construction keeps you from overheating. These work for outdoor workouts where you want coverage from the sun but not coverage that makes you sweat more. The fitted construction means the mesh stays close to your body so it does not bunch or shift during movement. Pair it over a sports bra or a fitted tank for the layering you need. The long sleeves actually work year-round depending on the fabric weight and the season you are training in. These mesh long sleeve tops are for people who want functional coverage without sacrificing breathability or comfort during activity.
