Oiselle is a Seattle-based by women, for women athletic apparel company. Their clothing merges all the best technical properties in athletic clothing (heat, sweat management, insulation, durability) with style that can be worn when you're not running too. Oiselle also sponsors professional women's track athletes, and has a running club for all women of all abilities with opportunities for meetups and training. Many of their styles give back to charitable programs too, like the Bras for Girls Program for middle school girls.
Some of my favorite items are the pocket jogger shorts, anything made out of the lux fabric, and the flyout tanks.
