The secret to the ultimate fabric for your shorts, leggings and sports bras

El secreto detrás del tejido de shorts, leggings y sujetadores deportivos

When it comes to shorts, sports bras or leggings, elasticity makes all the difference and the ability to move with every rep. That’s why cotton, although perfect for T-shirts, is not suitable for this type of clothing.

The true star is nylon, a fabric that plays in a completely different league than polyester.

The composition of nylon makes it more elastic, more durable and better at managing moisture. That’s why, when we talk about fitted training wear, nylon represents a higher level of comfort and performance.

Six advantages of nylon you may not know

1. Strength and elasticity

Nylon has a stretch capacity far superior to polyester. It can extend several times its original length and return to shape without deforming. This results in garments that move with every rep, every squat and every explosive motion without losing fit or comfort.

This elasticity is perfect for pieces that need to move with you, not against you.

2. Softness on the skin

Nylon feels smoother and silkier than polyester. In tight-fitting garments, that detail makes all the difference. After a workout, you want softness – not friction or discomfort.

3. Sweat management

Cotton absorbs a lot, polyester almost nothing. Nylon sits in the middle. It can absorb part of the sweat and help it evaporate, preventing the “dripping” feeling polyester often creates. In indoor training, that means more comfort and fewer distractions.

4. Odor control

Train, sweat, wash… and your clothes still smell? Polyester tends to retain more odor, while nylon does so to a much lesser degree. The result: garments that stay fresher for longer, even after intense sessions.

5. Light and quick-drying

Nylon is lightweight and dries fast. This prevents the garment from feeling heavy or showing visible sweat marks, keeping freshness and style even after a tough WOD.

6. The Spandex bonus

Nylon is already a quality fabric, but when combined with Spandex it becomes a true premium fabric. Spandex provides extraordinary elasticity and allows the garment to adapt like a second skin without losing shape.

Nylon and Spandex together create a premium fabric that is unbeatable for training wear. It costs more to produce, but it won’t give in a single millimeter during your workout.
But beware: Nylon+Spandex is not the same as Polyester+Spandex. Always check the label before you buy!

In short, nylon combines the best of both worlds: it doesn’t absorb as much as cotton, but more than polyester; it retains less odor and also offers lightness, durability and softness.

So if you’re looking for shorts, sports bras or leggings that last, feel comfortable and manage sweat effectively, nylon is the choice that puts you one step ahead.

And where to buy pieces made of nylon+spandex? Right here – because at Cocowod all our lower-body crosstraining clothing is made of nylon. See for yourself!
