By women, for women. The Oiselle brand's mantra is literally "By and for women athletes," and it lives by a sisterhood — an empowering, inclusive female community. Founder and CEO Sally Bergesen created the Seattle-based brand in 2007 and started with running shorts. Since then, the company has exploded in the women's fitness scene and delivers incredibly high-quality technical apparel that helps you look as good as you feel — whether you're fine-tuning your splits or taking your first steps toward a 5K.
