We've all been there: you're running in shorts, but the minute you toss your phone in the pocket they're so heavy, you feel like they're going to fall off. Lululemon's Fast and Free Shorts ($68) are truly the exception. These legging-style biker shorts have fuller coverage and quick-dry fabric that prevents chafing. Thanks to their supportive body-hugging design, any accessory placed in the side or lower back pocket is sure to stay in place without disrupting your comfort.
