Have you ever finished a workout feeling uncomfortable, sweaty, and with your clothes sticking to your body? The culprit, almost always, is the fabric. Choosing the best materials for activewear is not a whim: it's the difference between performing at your best or having your clothes hold you back before you reach your goal.
At Etereo House, we design each garment with the woman who truly trains in mind. That's why this guide exists: so you know exactly what you're wearing, why we chose it, and how it benefits every move you make.
What you wear matters
The best materials for training
There isn't one best material. There is a most suitable material for each purpose.
1
Polyamide
Etereo House's star fabric. Soft, second-skin feel, high elasticity, and quick-drying. We work with two sources that share the same high performance.
Second skin
High elasticity
Quick-drying
Very durable
Recycled ♻
From ocean fishing nets and industrial waste. Same performance, lower environmental footprint.
KM0 · Spain
Locally manufactured. Full traceability and support for the national textile industry.
2
Polyester
The only material compatible with sublimation: the technique that fuses ink with the fiber to create prints that won't peel, crack, or fade with washing.
Exclusive sublimation
Permanent colors
Light and resistant
Quick-drying
3
Lycra · Spandex
Stretches up to six times its size and returns to its original shape. Always combined with polyamide or polyester to add elasticity without losing durability or breathability.
Stretches 6× its size
Soft compression
No restrictions
4
Bamboo
Naturally antibacterial fiber with unparalleled softness. Ideal for lower intensity workouts or daily wear when skin needs to breathe.
Antibacterial
Hypoallergenic
Breathable
Sustainable
5
Cotton
The classic. Soft, familiar, and comfortable for low-intensity activities. Retains more moisture than technical fabrics, which is why we prefer other materials for training.
Very soft to the touch
Hypoallergenic
Retains moisture during exercise

Frequently asked questions
What is the difference between polyamide and polyester in activewear?
Polyamide offers greater softness, elasticity, and body adaptation. Polyester is more rigid but irreplaceable for sublimation. Both are quality technical materials with complementary uses.
What is sublimation in activewear?
It is a printing technique that fuses ink with the fabric fiber using heat. It only works on polyester and produces designs that do not peel or lose color with washing.
What is recycled polyamide?
It is polyamide made from recovered materials such as ocean fishing nets or industrial waste. It offers the same performance as conventional polyamide with a much lower environmental impact.
Is Lycra good for sports leggings?
Yes, it is the key material for compression and high-stretch leggings. It is always combined with polyamide or polyester for greater durability and breathability.
What is KM0 activewear?
It is clothing made with locally produced materials. At Etereo House, we use KM0 polyamide manufactured in Spain, which reduces the carbon footprint and guarantees product traceability.
Why is cotton not ideal for sports?
Because it absorbs sweat but does not wick it away quickly, making the garment heavy and damp. For medium or high-intensity workouts, technical polyamide is far superior.
At Etereo House, material is everything.
We work with recycled polyamide, KM0 polyamide manufactured in Spain, and sublimated polyester because we believe that performance, design, and responsibility do not have to be at odds.
