Athleisure--athletic clothing reenvisioned as everyday wear--is not merely an apparel category. Activewear represents a lifestyle shift. It's wellness for Boomers, self-care for Millennials, and a smidgen of ease we reclaim for ourselves in an uneasy world. Just under 100 percent of activewear users report donning workout clothes when they aren't exercising. Companies like Under Armour, Sweaty Betty, and Outdoor Voices are driving athleisure's ascent; the industry is expected to generate $232 billion in global sales by 2024. Even now, activewear claims 24 percent of all global apparel purchases. But the togs we wear while enjoying today's active lifestyles--or while eating takeout in front of the TV--have been finding their footing for decades.
