For intense exercise, functional fabric is the better choice. It actively wicks away sweat, dries quickly, and helps maintain body temperature. Cotton, on the other hand, absorbs moisture, stays wet for a long time, and can lead to chilling during breaks. For everyday wear, streetwear, and light activity, cotton scores points with its natural, soft feel.
Quick overview:
- Functional fabric (usually polyester or polyamide): active moisture wicking, quick drying, high elasticity, ideal for the gym, running, and outdoor activities
- Cotton (natural fiber): comfortable on the skin, breathable, but slow to dry and lacks active moisture transport
- Organic cotton (e.g., GOTS-certified): a more sustainable alternative to conventional cotton, using less water and fewer chemicals
- Recycled polyester: resource-efficient and high-performing, but with microplastic issues during washing
- Recommendation for sports: functional fabric for all types of exercise that cause sweating
- Recommendation for everyday wear: cotton or organic cotton for comfort and sustainable consumption

What properties distinguish functional fabric and cotton in sportswear?
Cotton is a natural fiber made of cellulose. It is skin-friendly and breathable, absorbs moisture well, and feels soft. This very absorbency becomes a problem during sports: The fabric retains sweat instead of wicking it away.
Functional fabrics such as polyester and polyamide are made synthetically. Their yarn structure is designed to transport sweat away from the skin through capillary action. The fabric stays dry, as does the skin.
Comparison of properties:
- Moisture management: Cotton absorbs, functional fabric wicks away
- Drying time: Cotton dries slowly, polyester significantly faster
- Elasticity: Functional fabrics are generally more elastic and shape-retaining
- Durability: Polyester is more tear-resistant and does not shrink; cotton can shrink with frequent washing
- Temperature effect: Cotton cools through evaporation, functional fabric regulates actively
Modern polyester fibers are similarly breathable to natural fibers and are characterized by high durability.
What are the pros and cons of cotton for sports?
Cotton has clear strengths and equally clear limitations in sports.
Advantages:
- Soft, natural feel directly on the skin
- Good breathability during light exercise
- Hypoallergenic and well tolerated by sensitive skin
- Affordable and widely available
Disadvantages:
- Absorbs sweat and dries slowly, leading to chilling in cold conditions
- No active moisture transport: The fabric becomes heavy and sticky
- Less shape retention with frequent washing and movement stress
- Unsuitable for intense training, as performance decreases when clothes are wet
Silke Off from the Hohenstein Institutes puts it directly: In sports, cotton has the major disadvantage that it stays wet for a long time once it gets wet. If you then take a break and get a draft, you will quickly get goosebumps.
Why is functional fabric superior for intense training?
Functional fabrics are designed for exercise. Their structure promotes the rapid evaporation of sweat and keeps the skin dry, even during long workouts.
Strengths during training:
- Active moisture wicking through capillary action
- Quick drying, even after heavy sweating
- High elasticity for full freedom of movement
- Shape-retaining: maintains its fit even after many washes
- Temperature regulation through a breathable fabric structure
In addition, at low temperatures and during long workouts, cotton poses a risk of chilling because the fabric retains sweat. Functional fabrics avoid this through dynamic moisture management. For running, cycling, climbing, or strength training, this is not a minor detail, but a real performance factor.
Sweat management, odor, and temperature: A direct comparison
| Criterion | Cotton | Functional fabric |
|---|---|---|
| Moisture management | Absorbs sweat, stays wet | Actively wicks away sweat |
| Drying time | Slow | Fast |
| Odor formation | Lower, as there is less bacterial growth | Higher: Bacteria such as Micrococcus thrive on polyester |
| Breathability | Good for light exercise | Good to very good, depending on the fabric structure |
| Temperature regulation | Cools through evaporation, poses a risk of chilling | Regulates actively, keeps body temperature more stable |
| Application | Everyday wear, light activity | Intense sports, outdoor activities |
One point deserves special attention: Functional fabrics can be more prone to odor formation despite good moisture wicking, as bacteria thrive better on polyester. Regular washing at the appropriate temperature is therefore important.
Care instructions:
- Cotton: wash cold, dry gently, prone to shrinking
- Functional fabric: delicate cycle, no high drying temperatures, monitor odor formation with regular washing
How does the comfort differ between the two materials?
Comfort is subjective. For many people, cotton feels warmer, softer, and more natural. This feeling is real and has its place, especially in everyday wear.
During sports, perception quickly shifts. Wet cotton sticks to the skin, feels heavy, and creates friction. Functional fabric stays lighter and drier, even if it feels smoother or more synthetic at first.
Objective factors:
- Freedom of movement: Functional fabrics with an elastane content offer more stretch
- Temperature comfort during breaks: Cotton cools down significantly, functional fabric less so
- Odor perception: Cotton smells neutral longer, polyester can start to smell musty more quickly
- Skin compatibility: Cotton is hypoallergenic, polyester can irritate sensitive skin
For everyday wear and streetwear, cotton is often the more comfortable choice. For high-performance sports, the functional advantages of synthetic fabrics clearly outweigh the disadvantages.
When are cotton and functional fabric best suited?
Functional fabric:
- Gym and strength training: high sweat production, freedom of movement required
- Running and cycling: moisture management and temperature regulation are crucial
- Outdoor activities and hiking: protection against chilling in changing conditions
- Travel: quick-drying, space-saving, easy to care for
Cotton:
- Everyday and leisure wear: comfort and a natural feel
- Light activities such as yoga or walking
- Streetwear and oversized styles: look and feel are paramount
Blended fabrics made of cotton and synthetics sound like the best of both worlds. In practice, however, they often hinder moisture management and should be avoided for clear usage profiles. If you are buying for sports, it is better to choose pure functional fabric. If you are looking for sustainable everyday clothing, opt for high-quality organic cotton.
What should you look for when buying sportswear?
Check the material composition:
- For sports: preferably 100% functional fabric (polyester, polyamide) or with a small elastane content for stretch
- For everyday wear: 100% cotton or organic cotton, preferably without blended fibers for better recyclability
Pay attention to certifications:
- Organic cotton is more sustainable than conventional cotton: less water consumption, no use of chemicals
- For recycled polyester, pay attention to origin information (e.g., from PET bottles)
Functional requirements:
- Moisture management: capillary action present?
- Elasticity: stretch for full freedom of movement?
- Fit: oversized for everyday wear, close-fitting for sports
Sustainability aspects:
- Recycling polyester from PET bottles reduces the need for new raw materials
- GOTS organic cotton has a better environmental balance than conventional cotton
- Microplastics when washing synthetic fibers: special laundry bags can help capture fibers
Value for money:
- High-quality functional clothing costs more but lasts longer and retains its shape
- Cheap cotton can quickly shrink or fade
Pro tip: If you want to buy sustainably, look for the GOTS seal on cotton and recycling information on polyester. Timeless cuts and good workmanship significantly extend the lifespan of every garment.
