Performance shirts for maximum performance

Our performance shirts are made for movement.
They are made from lightweight, breathable fabrics that wick moisture away and dry quickly.

No matter if it’s for running training, a fitness event, or team building – your shirt stays comfortably dry.
Ergonomic cuts ensure optimal freedom of movement, and flat seams prevent chafing.

Sportshirts mit nachhaltiger Verantwortung

At 9-Seconds, sustainability starts with the choice of materials: We use recycled performance fabrics (rPET & bio-polyester) that offer the same performance as conventional fabrics – but with a significantly lower ecological footprint.

All our shirts are produced exclusively in Europe, under fair conditions and with short transport routes.

This makes every shirt a visible symbol of sustainable action.

Design that moves

A good design evokes emotions.
With the 3D configurator, you can design your shirt according to your ideas – from sporty-modern to elegant and minimalist.

Whether for companies, clubs, or running groups:
You combine colors, graphics, and logos so that your shirt is not just worn,
but proudly displayed.

Your design. Your team. Your statement.

Sublimation printing – quality that lasts

For brilliant colors and precise logos, we use modern sublimation printing. The color is steamed directly into the fiber – no chemicals, no print layer.

Recycled performance fabrics (rPET & bio-polyester) are used, providing performance and comfort while conserving resources.

Even after many washes, the shirt stays like new – ideal for regular use in training and competition.

Team shirts that unite

Uniform sports shirts promote cohesion and motivation.
When everyone wears the same colors, a visible sense of unity is created.


This applies to sports teams as well as companies or running groups. An individual shirt turns individuals into a team – both visually and emotionally.

It is a symbol of performance, goal orientation, and unity.
