Q: What fabric are these compression shorts made from, and why does it matter for performance?
A: These shorts are made from 85% polyester and 15% spandex — and that combination is doing a lot of work. The polyester pulls sweat away from your skin and helps it evaporate fast, so you stay dry and cool even during intense sessions. The spandex gives you that snug, second-skin fit that moves with you, reduces muscle vibration, and helps fight off fatigue. Whether you're lifting, running, or just grinding through a long day, the fabric is built to keep up.

Q: Will these shorts cause chafing during long runs or high-rep workouts?
A: That's exactly what they're designed to prevent. The tight, form-fitting cut sits flush against your skin, eliminating the friction that causes chafing and irritation. If you've dealt with inner-thigh rubbing during runs or leg day, these are worth trying — the smooth, stretchy material creates a barrier that moves with you rather than against you.

Q: How do I know which size to order?
A: MRX keeps it straightforward — all sizes are based on waist measurements in inches. Small fits 30"–32", Medium fits 32"–34", Large fits 34"–36", X-Large fits 36"–38", and XX-Large fits 38"–40". If you're between sizes, sizing up will give you a more comfortable fit while still maintaining compression.

Q: Are these shorts only for the gym, or can I wear them for other activities?
A: These work well beyond the gym. The 4-way stretch and ergonomic design make them a solid choice for running, cycling, sports, or even wearing under work clothes if you're on your feet all day. The compression supports blood circulation and reduces muscle fatigue, which is just as useful during a long shift or a travel day as it is during a workout.

Q: How should I wash these to keep them in good shape?
A: Good news — they're machine washable, so no special treatment needed. To extend the life of the fabric and keep the compression intact, washing on a gentle cycle with cold water and skipping the dryer when possible is the way to go. High heat can break down spandex over time, so air drying is your best bet for keeping that snug fit long-term.
