Good top

Can’t go wrong with merino. Good top, not too hot.

My Wife loves this shirt!

Very well made and designed t-shirt. The merino wool wicks moisture well in the humid Malaysia. My wife loves it and I am happy it’s a nice and well built item. Wish they had this for men!

Partnerce přijde pohodlné v létě i v chladnějším počasí. Ideální je také na vícedenní výlety.


Geruchs- und Schweissaufnahme hat sich bewährt, Qualität nach dem Waschen muss sich noch zeigen.

Tolles Material

Mich stören lediglich die nach der Wäsche „wandernden Nähte“. Das ist bei meinen ersten Shirts dieser Art nicht gewesen. Da sind sie seitlich links und rechts geblieben .

Nicht wie abgebildet

Leider ist das Shirt nicht in solch einem sonnigen Gelb wie auf den Fotos, sondern eher senffarben. Die Farbe ist Geschmacksache, ich hatte hier allerdings etwas anderes erwartet. Zudem ist das Shirt extrem durchsichtig, daher der Punktabzug.

Sehr gut alleine oder als Middlelayer...

... Farbe ist nicht wie Abbildung - mehr dunkles bordeaux rot. Farblich trotzdem gut mit dem Wanderoutfit von 2020 harmonierend.

Additional Product Information


Main fabric

  • 89% Wool
  • 11% Polyamide


  • 66% Wool
  • 24% Polyamide
  • 10% Spandex

What are our commitments in favor of animal welfare?

We only use wool from Merino sheep bred on farms in South Africa that do not practice mulesing. We decided to build a partnership with a group of breeders (Konsortium Merino) to guarantee respect for animal welfare and the environment. We have full traceability, which allows us to guarantee the origin of the wool. More information: Visit our website

How did we improve the durability of our t-shirt?

Use of a BETA-SPUN thread structure in which the polyamide threads coat the Merino wool fibers and protect them from rubbing and cuts without affecting their technical properties.

How does wool reduce the proliferation of bad odors?

Wool from Merino sheep naturally controls the spread of bacteria that cause bad smells. It can therefore be worn several days in a row and means you can take less clothes when backpacking!

Reducing the "freezing effect"

After any physical effort that involves a lot of perspiration, wool helps to preserve the body temperature while synthetic fabrics cause the temperature to drop faster. The unpleasant cooling or "freezing effect" is therefore reduced by the merino wool.

How do you wash your merino wool t-shirt?

We recommend that you machine wash your Merino wool T-shirt at 86°F on a normal cycle, preferably with liquid detergent. Dry flat. NEVER tumble dry unless you want to end up with a Merino T-shirt fit only for a doll! For more information:

Do you have a final word of advice before using it?

For a softer feel, wash your T-shirt before 1st use.



Product testing

The Trek 500 merino T-shirt was tested in summer 2020 in the Northern Alps, both for mountain backpacking and other outdoor sports. These tests enabled us to validate the product in use.
