Conquer the elements. Take the throne. Rule. Merino Extreme thermal wear is a true conqueror of previously unconquered areas of the sport. High-weight 100% New Zealand wool will take you to the edge of the world. It's not for nothing that the holder of the Himalayan Crown, Radek Jaroš, wears this functional underwear.

Sewn at the foot of the Hostýn Mountains and bearing the Extreme label, this merino shirt will support you even in the harshest conditions. Where others freeze, you stay warm. The perfect thermoregulating properties of merino clothing are brought to an absolute peak here. Don't worry about uncomfortable moisture. Thanks to the merino wool used, this functional underwear will keep you warm even when it's wet.

Finally, there's a material that does its job to the maximum. Go beyond the edge and don't worry about failure. Our Merino Extreme thermal underwear will serve you for many years. Despite its softness, it maintains its durability, and thanks to its lasting antibacterial protection, you don't have to worry about putting it on even after a few extra tough missions. Arm yourself with the comfort of natural material of the highest quality and go boldly into the wilderness.

It's worth going to the extreme. Take the crown that's rightfully yours in the Merino Extreme thermal underwear. Just like Radek Jaros did with the Himalayan. Stay warm even when you're walking through a merciless ice inferno. Remember your limits. And overcome them!

A very warm novelty in the knitwear collection is Merino Extreme suitable for (not only) extreme conditions! This high weight rib knit is made of 100% Merino wool with Lycra.

How to care for Merino Extreme products

Clothes made of sheep's wool only wash in hand in the moonlight. No, we're kidding. Those days are long gone. Sheep's wool is naturally antibacterial, so it can withstand repeated wear. And even sheep's wool socks! That's why merino clothing is a great partner for long hikes.

But nothing should be overdone and you should care for the wool like you would your own coat, so follow our guidelines:

Avoid changing temperatures! Washing and soaking must be done in water at the same temperature to avoid shrinking the clothes. A smart washing machine will maintain the temperature for you when you select the wool programme. Don't exceed 30 °C (don't worry about lower temperatures), spin the drum at 800 rpm max to avoid breaking the fibres.

Fill the washing machine only ⅔ full and use a powder designed for wool, preferably Lanolin. Do not use fabric softener.

NEVER dry on the heater. Don't hang your clothes but spread them out on the drying rack. Dry the clothes lightly with a towel beforehand so they are not too heavy.
