1. **Comfort:** Look for soft, stretchy fabrics like spandex or polyester blends that move with you and don’t restrict your range of motion. A good pair of shorts should also have a wide, elastic waistband that stays in place without digging into your skin. 2. **Breathability:** Breathable materials are essential to keep you cool and dry during intense workouts. Moisture-wicking fabrics help manage sweat, preventing discomfort and chafing. 3. **Fit:** A snug fit is ideal for most activities as it prevents the shorts from riding up or bunching. However, if you prefer a looser fit, look for shorts with side slits or a relaxed cut that still allows for full mobility. 4. **Length:** The length of gym shorts can vary from short (2-3 inches inseam) to longer options (6-8 inches). Shorter lengths are great for maximum movement, while longer shorts offer more coverage and are ideal for activities like cycling or running. 5. **Pockets:** Functional pockets, especially zippered ones, are a big plus for storing small items like keys or a phone during your workout.
