Lululemon Athletica

This popular Canadian company—whose clothing is designed in part by working yoga and fitness instructors—may be a bit upscale, but innovative ideas, such as reversible pants and zipper pulls that double as hair ties, justify the hefty price tags. The company employs extremely durable fabrics like Silverescent (which inhibits the growth of odor-causing bacteria and fungus) to create pieces that you’ll be inclined to wear outside of the yoga studio, too.
