Product Testing

Where performance is tested, not promised.

At Next Extreme, performance isn’t a marketing claim — it’s a standard.
Before a product launches, it goes through an intensive testing process that goes beyond an average workout.

We don’t test our performance wear in theory.
We test where it counts: under load, in motion, and over time.

Why product testing is essential

Performance wear should never distract.
It must support, move with you, and stay reliable — especially when intensity rises.

That’s why we test every product with one goal:
consistent performance, training after training.

From fabric selection to the smallest detail, nothing is approved unless it meets our performance standard.

Squatproof testing

One of the most important tests for our leggings is the squatproof test.

Every fabric is tested during:

• deep squats

• lunges

• hip thrusts

• movements under maximum stretch

We test under different lighting conditions and on multiple body types to prevent transparency.

The result:
Our leggings remain fully opaque, no matter the movement or intensity.

No uncertainty.
Full focus.

Stretch & recovery test

Stretch alone doesn’t make performance wear.
True performance means the fabric returns to its original shape.

That’s why we test for:

• 4-way stretch

• shape retention after intensive use

• waistband stability

• support without pinching

The fabric moves with the body and then recovers without sagging or losing structure.
This prevents slipping, rolling waistbands, and loss of compression.

Wash & durability test

Performance wear must not only perform during training but also over the long term.

We test for:

• color retention

• fabric quality

• elasticity after repeated washing

• seam durability

• logo lifespan

Our signature 3D silicone logo is applied a few millimeters thick and tested for flexibility and adhesion.
It doesn’t fade, tear, or come loose — even with intense use and frequent washing.

Durability is not an extra.
It’s a requirement.

Tested in motion by athletes

Our products are tested not only under controlled conditions but also in real training situations.

Athletes wear our performance wear during:

• strength training

• conditioning

• high-intensity workouts

• long training sessions

Their feedback determines the final fit, support, and comfort.
Only after multiple test rounds is a product finally approved.

Tested to perform. Made to last.

Product testing is not just a marketing story for us.
It’s the foundation of everything we do.

Every detail is critically evaluated because there’s no room for compromise when performance matters.

Does a product not meet our testing standard?
Then it doesn’t make the collection.

That is our promise.
