Merino wool neutralizes unpleasant odors by absorbing odour molecules into its fibers, making them less detectable by the human nose.
Merino fibers efficiently manage moisture, absorbing it from your skin and releasing it into the atmosphere. It can absorb up to 35% of its weight in water without feeling wet.
icebreaker merino wool garments undergo special anti-shrinkage treatment, helping to resist deformation and pilling.
The thermo-regulation properties of merino wool adapt to your body and external conditions, so you can stay warm in the cold and cool in the heat.

"This is a high quality 200 weight form fitting t-shirt with no logos. It would be perfect with a suit, sport coat, or by itself in casual settings."
— Paul (5/5)
"The Merino 200 weight has held up great. I’ve been wearing it multiple days every week for months at work and no runs or holes like the Merino 150 weight Tech lite gets. It’s not to heavy to wear in the summer even when you are working hard. . I will certainly order more and highly recommend it"
— Michael G. (5/5)
"Excellent. I bought it for our trip to Portugal to do the Camino De Santiago. Wore it every day for 15 days as we walked across Portugal and Spain. Washed it a few times. Wicked away moisture, no smell. Could not have asked for more."
— Ralph R. (5/5)
"Love these shirts, I own short and long sleeve ones. Very soft and warm, can wear for days without washing. Only thing is they run small so I had to go up a size"
— Tim S. (5/5)
