Best Fabrics for Running Clothes for Comfort & Performance
Choosing the right running clothes starts with understanding fabric. The material your clothing is made from plays a key role in how comfortable you feel, how well you regulate temperature, and how effectively you manage sweat on the run. From hot summer miles to cold-weather training, the best fabrics for running help keep you dry, reduce irritation, and support consistent performance in any condition. Our Running Experts break down the best materials for running clothes, and what to avoid.
Why Running Clothing Fabric Matters
No matter the distance, pace, or weather conditions, you’ll sweat when running. The right fabric helps manage that moisture and temperature so you can stay focused on your run.
Running-specific clothing is designed with three performance needs in mind:
-
Stay Dry: Fabrics that wick sweat away from your skin and dry quickly help keep you comfortable and reduce the risk of chafing.
-
Regulate Temperature: Breathable materials help release heat in warm conditions and manage moisture in cold conditions to keep you comfortable.
-
Avoid Friction: Smooth, flexible fabrics reduce rubbing and irritation over longer runs.

What Fabrics to Look for in Running Clothing
Most running apparel uses performance blends, but these are the key fabrics you will see most often.
Polyester
Polyester is one of the most widely used fabrics in running apparel because it’s lightweight, durable, and designed to wick moisture away from the skin.
Why runners choose it:
-
Lightweight and breathable
-
Quick-drying and moisture-wicking
-
Works well across most weather conditions
-
Common in shirts, shorts, and base layers
Nylon
Nylon is known for its strength and smooth feel, making it a great option for running shorts, tights, and outer layers.
Why runners choose it:
Spandex / Elastane
Spandex, often blended with other materials, adds stretch and flexibility to running apparel. It’s rarely used on its own but is essential for fit and movement.
Why runners choose it:
-
Helps clothing maintain its shape
-
Adds stretch for natural movement
-
Improves comfort in fitted gear like tights and compression shorts
Merino Wool
Merino wool is a natural fiber that performs well for running, especially in cooler conditions. Unlike traditional wool, it’s soft, breathable, and temperature-regulating.
Why runners choose it:
-
Resists odor buildup over time
-
Naturally regulates temperature
-
Helps keep you warm without overheating
-
Ideal for cold-weather base layers

Best Fabrics by Running Conditions
Although many of the fabrics in running clothing are a blend of materials, you can consider your conditions and match your running outfit accordingly. Here’s a general breakdown of which fabrics shine depending on the conditions:
Running Condition | Best Fabrics | Why |
|---|---|---|
| Hot Weather (Summer) | Polyester | Lightweight and highly breathable |
| Cold Weather (Winter) | Merino wool or brushed polyester | Warm with moisture control |
| Rainy / Windy | Polyester or nylon | Wind protection and durability |
Expert Tip | Avoid cotton when running. It absorbs and holds moisture, which can leave you feeling wet, heavy, and uncomfortable—and may increase chafing during your run.
