Arne, our warm flannel merino shirt.

400g of superfine merino wool that's meant to keep you warm. Its flannel fabric is luxuriously soft on the outside and pleasantly smooth on the inside.

And just like all our shirts, wrinkles and odours are a thing of the past. That's the natural work of merino wool.


what our customers say
Keeps me warm but never gets too hot. Top notch material, never smells although I rarely wash it.
— Ivan
It's pricy but really worth the money. Bought a second one.
— Jerome
I have worn this shirt for most of the time this winter. It fits perfectly and it's warm enough to wear without a sweater. I just wear one of my merino tees underneath.

Standard detergents contain harsh enzymes that can break down natural wool fibers.

This specialized care preserves the wool's softness, shape, and natural moisture.
Using the right detergent extends the life and performance of your garments.
