This T-shirt redefines our brand's iconic, muscle-accentuating cut with premium interlock fabric . Its thick weight offers a much more substantial look than typical white T-shirts. With its ribbed collar and sheer fabric, it's designed specifically for anyone looking to create a simple yet powerful style. It stands out as a powerful piece for both everyday wear and more stylish outfits.

This long-sleeved t-shirt is designed for men who want to combine a toned, muscular look with a premium fabric experience.
The Oslo takes the beloved interlock structure of the Copenhagen model and gives it a long-sleeved form, offering a strong silhouette that can be worn in every season.
The thick, weighted interlock fabric hugs the body while creating a firm and balanced look; its non-see-through structure provides confidence whether worn alone or layered.

The Qsimple Muscle Up Fit design creates a wider silhouette, accentuates the bust, and subtly balances the abdominal area.
Available in black, dark navy, and white, it offers a minimalist, modern, and timeless aesthetic.

Why Oslo Long-Sleeve T-Shirt?

It provides extra warmth on cold days, while its structure allows for comfortable use in warm weather.
Worn under a jacket, over denim, or on its own — the Oslo is a long-sleeved interpretation of understated luxury in the modern man's wardrobe.

The collar part is thicker and ribbed; it does not deform over time, preserves its form and provides a strong stance.
