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.

"I really liked this shirt for summer hiking. It's supper light. I only wore it a few times, several longer backcountry trips, and washed it only a couple of times. It developed a hole in the back on the bottom where my pack hits, hiking out of the Grand Canyon. I was expecting more from a $90 t-shirt."
— Flipper (1/5)
"Overall I like the icebreaker brand and clothing. However, the fabric used in a number of their lightweight shirts, especially this one is not very durable. It does not appear that icebreaker performs real world fabric abrasion testing. I only washed this shirt by hand. The material pulls easily and the pulls subsequently develop into holes."
— Ron (1/5)
"I have about 6 of this t-shirt. I wear it everyday( mostly on training sessions ). The main advantage is that it doesn't smell fast. The fibre is delicate and you don't feel too warm when you sweat."
— Yev (5/5)
"I was looking for something suitable for medium to high-intensity workouts. I really like this one, so I ordered two more. It’s not too warm, but it does resist odor. The fabric feels soft — I don’t like 100% merino base layers or shirts because they usually aren't this delicate. Size matches."
— Yev (5/5)
"love how cool it is when working out in the hot sun."
— Nik (5/5)
"I have been wearing this shirt all summer and it has performed very well in hot conditions. This shirt is perfect for running, hiking, pickleball or working out and is extremely breathable and odour resistant."
— Kevin (5/5)
"Perfect on the court indoors and out. Flat seems are super comfortable even when working up a sweat."
— Marty (5/5)
"The fit is great. Doesn't stink after a long run. 10/10 would buy again"

"Really nice , slightly open weave , very comfortable. Great for the gym and hot days."
— Fergus (4/5)
"Fits close to body but not tight. Fabric is light weight and breathes well. Looking to purchase another."
— Rick (5/5)
