The North Face Velocitee Crew - Short-Sleeve - Women's - $19.95

Cotton isn't exactly Killer Cotton in the summer, but it still isn't so great to do your thing on the trail in a soggy tee. The North Face Women's Velocitee Crew is just as soft as cotton threads, but it will help you wick away the sweat as you put in your daily five miles. If the sun is out and blazing, the Velocitee fabric will help protect you from sunburn during your workout. - $19.95
