If you're going to run in the sun you need the Direct-Vent cooling panels on this running short.

Not everyone can roust themselves from bed at 4:00 AM for a morning summer run. If you have to run in the heat opt for the ventilated comfort of these lightweight and highly breathable Aurora Shorts from Pearl Izumi. Pearl added Direct-Vent panels along the front and back to enhance the cooling throughout the fast-drying and lightweight polyester inner liner. The shell fabric is a blend of Spandex and polyester for enhanced stretch and there is a partial side split for improved range of motion. The Aurora is a great running short for hot days--and those times when a sadistic race director thinks it's a good idea to have a marathon race start at 9:30 AM in the middle of August.
