The tank top built for your physique.
Core Activewear. Our story
The story
In February 2026, Luka decided to create a clothing brand. Always searching for the perfect pieces, whether for sport or everyday life, he faced a simple realization: no garment truly combines structure, comfort and premium quality. The cuts are approximate. The fabrics are ordinary. Nothing is designed to highlight the body while staying clean and refined. Kontrol was born from that gap.
CORE
The ambition is clear: to create structured, comfortable clothing, made with premium fabrics, built to last and to flatter without compromise. Pieces that adapt to every moment: at the gym as well as in everyday life. But CORE goes further. It's not just a brand. It's a code of conduct. A vision for those who want to take back control of their lives, to be disciplined, demanding, and committed to their progress.
The first piece
Luka started by developing a tank top. An essential piece. Timeless. Designed to be worn at the gym as well as in everyday life. Everything rests on the cut. A controlled opening under the armpits. Clean coverage of the back muscles. A fitted collar for a clean, structured look. Every detail is calculated to create a sharp, balanced, controlled silhouette. The fabric completes this standard. A premium, slightly stretchy fabric that hugs the body without restricting it, highlights the physique and follows every movement. This tank top was designed with one simple idea: to showcase the body you've built. No compromise between style, comfort and standards
Constant evolution
Core is a brand in motion. Every piece evolves. Every detail is optimized. We move forward with one single logic: listen, adjust, improve.
The global vision
Core's goal is to rethink every piece of the athletic wardrobe. To offer the right balance between comfort, practicality and aesthetics. To allow you to train with high standards, progress, and maintain that same level in everyday life. Because nothing should be left to chance

Perfect fit
Finally a tank top that fits the body perfectly. People even asked me where I bought it because the cut looks so good. I just reordered a black pack, white is next.
Exactly what I was looking for
Fitted and stretchy cut, exactly what I was looking for. I feel really good in it.
The best I've tried
Perfect fit, and it really highlights the shoulders and arms. Plus it covers the chest and sides well, it doesn't look like a 'cut-up t-shirt
Nothing to complain about
As described, nothing to complain about. I'll buy again.
Incredible look
Incredible cut, incredible look. Nothing else compares.
Ultra comfortable
Perfect size and feels amazing on the skin.
Superior quality
For reference: 5'9", 165 lbs, I took an L. Perfect fit and quality above any brand I've owned. I got 6 white and 6 black
