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.
Overall rating: 5.0 / 5 from 10 reviews.

"Got it for my husband who didn't believe in it. I insisted him to try them out on his 10mile run. He was super happy after the run. He mentioned it didn't make his feet itchy or hot towards the end of the run which is an issue he faces on long runs"
