This calculator rates a fabric's ability to pull moisture (like sweat) away from your skin and move it to the outer surface to evaporate. You'll select a fabric type and your activity level, and the calculator will provide a 'Moisture-Wicking Efficiency' score. A higher score means the fabric is more effective at keeping you dry.

Effective moisture-wicking is crucial for comfort during exercise or in hot, humid weather. When sweat sits on your skin, it can cause chafing, irritation, and a 'clammy' feeling. In the cold, a wet base layer can be dangerous as it can lead to a rapid loss of body heat. A good moisture-wicking fabric keeps you dry, comfortable, and safe.

The 'Moisture-Wicking Efficiency' score helps you choose the best fabric for your activity. For high-intensity workouts, you'll want a very high score, which you'll find in performance synthetics like polyester or polypropylene. For low-impact activities or everyday wear, a fabric with a moderate score, like merino wool, might be perfect. This helps you match the fabric's performance to your needs.

• For the best performance, your moisture-wicking layer should fit snugly against your skin.
• Look for garments with flatlock seams to prevent chafing during intense activity.
• A moisture-wicking sports bra is one of the most important pieces of gear for any active woman.
• Even your socks should be moisture-wicking to prevent blisters and keep your feet comfortable.
• To restore the wicking properties of your athletic wear, you can occasionally wash it with a specialized technical fabric wash.
