When it comes to workout outfits, most people want the leggings and sports bras they slip on bleary-eyed in the morning to be both stylish and functional. That’s why the active and loungewear spaces are booming with options for all shapes, price points and fitness levels. But it’s more than just a matter of style—the type of fabric your clothes are made from and their fit play a big role in the effectiveness of your workout.

High-impact exercise, like HIIT, requires clothing that offers compression and support; low-impact activity, like yoga, demands soft, stretchy fabrics that feel comfortable and don’t restrict movement. The right fabric will also help you manage your body temperature. For example, cotton can absorb moisture and feel heavy and wet when it becomes damp, but specialty fabrics that wick away sweat are much more effective for high-intensity workouts.

Other common traits of workout clothing are that they are quick-drying and provide breathability. That’s especially important in hot temperatures, but even when you’re exercising indoors in the winter, vented outer layers can help keep your body from overheating as it works up a sweat.

If you’re looking to invest in workout gear that supports your goals, try a pair of Nike running shoes with reinforced stitching and cushioning, or Alo’s long-sleeve bodysuits and pleated tennis skirts, both of which have been worn by celebs like Kendall Jenner. Both brands offer high-quality performance fabrics, like Airlift and Alosoft, as well as on-trend silhouettes for all the upcoming yoga classes and spin sessions you have planned.
