The Aero has a light, soft and springy feel when you put it on. The 120 featherweight material is made with 90% merino wool and 10% nylon. Icebreaker tags each garment with a unique “baacode,” which allows customers to learn more about the New Zealand merino wool farms that produced the wool for their garments. I typed my shirt’s “baacode” into the Icebreaker website and traced the wool in my shirt to 5 of their 120 merino farms.
I’ve been wearing this shirt around town, while hiking and even as a sleep shirt while camping. The 120 featherweight material is thin, but feels relatively durable. The 10% nylon likely adds a bit of strength to the material.
Seams and Side Panels
Icebreaker uses flatlock seams along the shoulders and around the side panels of the shirt. Flatlock seams are, as you might suspect, flat, and they feel more comfortable underneath backpack straps. The side panels, which eliminate seams under the arms, prevent chafing and make the shirt feel more comfortable when moving around.
Performance
As I mentioned before, I slept in this shirt, wore it casually around town and hiked in it. It’s soft and comfortable enough to sleep in and more stylish than your average T-shirt. As a hiking shirt, I thought it was fairly breathable and quick drying. For me, it was perfect for 60 and 70 degree weather. It proved to be a tad warm for me when temperatures rose into the 80s and 90s. I also wore this shirt for multiple days between washing and found it to be very odor resistant. Whether or not the people around me felt the same way, I’m not sure.
