Cotton vs French Terry vs Fleece: Which Hoodie Fabric Is Most Breathable?
Why Breathability Matters
When you put on a hoodie, what do you want to feel? If it is summer or you are indoors, you want to stay cool and dry. If it is winter, you want to stay warm. Breathability is what makes this possible.
What Breathability Actually Means
Breathability is how easily air passes through the fabric. High breathability means air flows freely. Low breathability means air is trapped.
Why does this matter? Because picking the wrong fabric can ruin your comfort. Wear a low-breathability fleece in a heated office, and your back will be wet with sweat in an hour. Wear a highly breathable cotton hoodie outside in freezing weather, and you will shiver.
This guide compares three popular hoodie fabrics—cotton, French terry, and fleece—to help you pick the right one for your needs.
The Breathability Ranking: Which Fabric Wins?
1st Place: Cotton – Most Breathable
Cotton is a natural fiber. It comes from plants. The fibers have tiny gaps that let air pass through easily. This is why cotton feels cool and comfortable in warm weather.
According to a 2026 fabric report from Alibaba Product Insights, cotton’s breathability is rated as “Excellent”. The Touches Dark fabric guide also notes that cotton has “excellent breathability”.
Cotton has other good qualities too. It is soft, gentle on sensitive skin, and comfortable all day.
But cotton has downsides. It shrinks in hot water. It wrinkles easily. When you sweat, cotton absorbs the moisture but dries slowly.
Best for: Everyday wear, warm climates, people with sensitive skin.
2nd Place: French Terry – Very Breathable
French terry is a medium-weight knit fabric. The outside is smooth. The inside has soft loops.
Those loops create tiny air pockets. Air can still move through, but the fabric is slightly thicker than cotton. This gives it a balance of breathability and light warmth.
The Alibaba report rates French terry’s breathability as “Very Good”. The Athleisurebasics fabric guide also emphasizes that French terry has “high breathability”.
Users who bought French terry hoodies from GU have shared their experiences. EZzzz from New York wrote: “This French terry hoodie is very comfortable and breathable, making it perfect for everyday wear.” Another user, Chase from New York, noted: “The hoodie fabric is on the thin side which makes it so comfortable as an inner layer.”
French terry also handles moisture better than cotton. The loops help pull sweat away from your skin.
Best for: Spring and fall, working out, layering under jackets.
3rd Place: Fleece – Least Breathable
Fleece is made from polyester, a synthetic material. The fabric goes through a process called “brushing”. Wire brushes comb through the fibers, creating a soft, fuzzy surface.
This fuzzy surface traps air. That is great for warmth. But it is bad for breathability. Air cannot move through easily.
The Alibaba report rates fleece’s breathability as “Fair”. The Touches Dark guide explicitly notes that fleece has “poor breathability”.
Fleece keeps you very warm. It is lightweight and dries fast. But it can make you feel stuffy indoors or during activity.
Best for: Winter, outdoor activities, cold climates.
