The difference between knitted and woven tracksuit jackets and pants.

The Track Suit That Ripped at the Seam

A few months ago, a friend of mine bought a tracksuit online. It looked sharp in the photos. When it arrived, he tried on the jacket and raised his arms to stretch. The fabric felt stiff. Then he heard a pop. The seam under the arm had torn. He was frustrated. He returned it and asked me why that happened. I looked at the tag. It said “woven polyester.” I explained that woven fabric has no stretch. For a tracksuit jacket that needs to move with your body, a knitted fabric would have been much better. That conversation started a deep dive into the difference between knitted and woven tracksuits. Let me share what I have learned from working with garment manufacturers.

Stretch, Softness, and Breathability From Interlocking Loops

Knitted fabric is made by continuously looping yarn together, similar to how you knit a scarf by hand. This construction creates a fabric that naturally stretches in all directions. Because the loops can open and close, knitted fabric feels soft against the skin and allows air to pass through easily. This makes it breathable. Common knitted fabrics include jersey, fleece, and rib knit. For tracksuits, a knitted jacket or pants will move with you when you run, bend, or reach. You will not feel restricted. The fabric also drapes nicely, meaning it hangs smoothly without looking boxy. However, knitted fabric can be less durable against heavy abrasion and may pill over time. But for comfort and flexibility, knitted wins every time.

Stability, Structure, and Durability From Crossed Threads

Woven fabric is made by interlacing two sets of threads at right angles. The warp threads run lengthwise, and the weft threads run crosswise. This tight, grid like structure produces a fabric that has very little to no stretch. Woven fabrics hold their shape well, resist wrinkling, and are highly durable. Common woven fabrics include cotton twill, nylon taslan, and polyester Oxford. For a tracksuit, a woven jacket will have a crisp, structured look. It blocks wind better because the threads are packed tightly. It also resists snagging and tearing. The downside is that woven fabric does not give. If you need to lift your arms above your head or do a deep squat, a woven tracksuit may bind or even rip, as my friend learned. Woven is better for outer shells or casual wear where movement is limited.

Knitted Jackets for Warm Up, Woven Jackets for Wind Protection

Let me break down how each fabric performs specifically in a tracksuit jacket. A knitted jacket is ideal for warm ups, gym training, or indoor activities. You can layer it over a t shirt and still have full shoulder and arm mobility. The fabric is quiet, too. It does not make that swishing sound that some windbreakers produce. Many athletes prefer knitted jackets because they feel like a second skin. On the other hand, a woven tracksuit jacket shines when you need protection from wind or light rain. The dense weave blocks drafts. It also looks more formal. Some woven jackets have a water repellent coating. If you are riding a bike or walking on a windy day, a woven jacket will keep you warmer. But do not expect to do jumping jacks in it. For a team tracksuit that players wear on the sidelines, a woven jacket looks sharp and professional. For actual training, knitted is the way to go.

Knitted Pants for Yoga, Woven Pants for Travel

For tracksuit pants, the choice depends on the activity. Knitted pants, often called sweatpants or joggers, are the most popular choice for lounging, yoga, or running errands. The elastic waistband and stretchy legs let you move freely. They are also warmer because the looped construction traps body heat. However, knitted pants can bag out at the knees after long wear. They may also attract lint and pet hair. Woven tracksuit pants have a smoother, cleaner look. They resist wrinkles and hold a crease. Some woven pants are made with a little bit of spandex blended in to add stretch, but they still feel more structured than knitted. Woven pants are great for travel because they look neat after being stuffed in a suitcase. They also work well for casual office days or dinner outings. But for intense leg movement like squats or lunges, woven pants may feel restrictive. A good compromise is a woven pant with a gusseted crotch or a small percentage of elastane.

After reading this, you might still wonder which fabric is right for your tracksuit. The answer depends on your use case. For a team training uniform, go with knitted for comfort and mobility.
