"It's not an exaggeration to say I've been living in exclusively stretchy pants these last eight months: if I'm working out, working from home, going for a walk, or running errands, I'm most likely wearing a pair of stretchy leggings. That's why I was so excited when Lululemon sent me a pair of its Wunder Under High-Rise Tight Full-On Luxtreme ($98). I'm usually a black leggings gal, but the navy colour is a subtle way to mix it up. They are buttery softs and good for performance (I tried them on a stationary bike and doing some bodyweight moves), and comfortable to wear all day while WFH." — Christina Stiehl, senior editor, Fitness
