Borderline Magic
"I bought a sale shirt (not this one, but the same material) to use for sports. I sweat. A lot. Easily soak through the shirt in an hour. It wicks amazingly well and doesn't cling. No, it doesn't defy the laws of physics and dissipate moisture into the atmosphere as if it didn't exist. My shirt gets heavy and sopping wet. But the magic happens afterwards at home. I hang the shirt, it dries fairly quickly, and smells like it was just washed. I have no idea how. I've even tried wearing it multiple times in a row and the thing just won't stink. I have lots of IB tees and this one's performance really is borderline magic to me."

Great shirt
"I bough 3 of these on the end of season sales and they are grrrreat! I do with the fiber blend percentages were reversed though more wool for better order resistance."

I do believe I’ve found my shirt…
"The silky smooth feel of the fabric is fantastic and the lightweight is perfect for hot n humid summer days outdoors, it’s quickly become my go-to. The odor resistance on long day hikes has been excellent, it dries quickly and it’s altogether been an outstanding alternative to the poly blends that I’ve ditched from my wardrobe. Bought this hoping it’d check all boxes for my thru hike of the Adirondack NPT in September and I do believe I’ve found my shirt. 👍👍"

works but runs smaller
"I like the color and fabric the medium fitting is smaller than the normal mediums I get in the other icebreaker shirts"

Poor quality
"Front of the t-shirt worn off very quickly . It looks like wool is dissipated only synthetics left. No idea how, it is not close to scratchy areas like belt, most likely poor quality."

Versatile Backcountry Staple
"I received this product for free in exchange for my honest review, and I made sure to put it through the ringer. This became my go-to shirt for all outdoor activities: 3 camping trips, 3 mountain peaks, and the gym, ranging 30-75 degrees. The fabric is thin, light, and breathable but robust enough to scrape against trees without issue. On warmer days, the 125 weight material is perfect. In high humidity, exposed fabric wicks and dries quickly and holds warmth when a cold breeze comes. It layers very effectively in colder temps. Being breathable, it pairs well with active insulation to deliver dry warmth. The softness makes it great for outdoor activity and casual wear. I slept in it while camping and wore it to a brewery after finishing one of my hikes- and being wool, it didn’t stink. It washes well without any pilling and maintains its size. As a larger guy (6’2” ~240lb) I sized up to XXL knowing that I wanted a baggier fit; Icebreaker XLs fit me snug- perfect for baselayers."

Less sweat and less stink
"I received this product for free in exchange for my honest review. I've really enjoyed wearing this ice breaker shirt for my runs. It's very breathable and helps keep the moisture away from my body. After wearing it on a couple runs, I wore this shirt for a 14 mile trail race to really put it to the test. It was a hot and humid day and the shirt helped keep me cool mile after mile. I experienced no chafing and it felt so soft on my body. I think because of the antimicrobial nature of the merino wool, I didn't smell nearly as bad as I feared I would and was able to enjoy the post race festivities without fear of grossing people out."

Great fit and performance
"Used this first on many hikes and runs. The wool did its job with keeping me cool amd dry. The fit is the highlight of this shirt. Fits directly against your skin and slim. Only con is the wool is rough on the skin compared to other brands I have tried. Definitely try this shirt on to make sure you like the fit. If you do, this is a great option. Seems very durable."

Merino That Actually Breathes: A Trail-Tested Revi
"I tested this shirt across many outings including trail runs (6–9 miles) and hikes (8–12 miles), in temps ranging from 58°F at dawn to 82°F by midday, including wind and light drizzle at elevation. Performance in motion was the standout. Breathability was excellent even at high effort, sweat moved away from skin quickly without any cling, and arm mobility was completely unrestricted. Temperature regulation impressed me too, it offered just enough warmth on cold morning starts and transitioned smoothly as effort ramped up, without trapping heat. Fit was true to size with a slightly athletic cut that layers cleanly under a softshell without bunching. Next-to-skin comfort is exceptional, with no itch at all, which is worth emphasizing for anyone skeptical of merino. I received this product for free in exchange for my honest review."

Cool with room for improvement
"★★★★☆ I tested the Icebreaker 125 Sphere Cool-Lite Short Sleeve Tee on trail runs ranging from the mid 60s up into the low 80s. Overall, it’s a really comfortable shirt that does a lot well, but I think there’s still room for improvement when it comes to hot-weather performance. The standout feature for me was how soft the fabric feels. This is one of the softer running tees I’ve worn and it’s comfortable both dry and soaked with sweat. Once I got sweating, the shirt actually felt noticeably cooler as the fabric wetted out, which helped during warmer climbs and exposed sections of trail. Odor resistance was also excellent. After multiple runs it stayed far fresher than a typical synthetic tee, which is one of the big advantages of merino blends like this. That said, for a shirt marketed toward keeping you cool, I honestly think it could be lighter. In temps pushing into the 80s, I found myself wishing for either a thinner fabric, mesh panels, or some sort of added ventilation. It performs well enough, but it doesn’t disappear on your body the way the best hot-weather running shirts do. One other thing: if I were buying it myself, I wouldn’t choose black. A dark color kind of defeats the purpose of a shirt designed for hotter conditions since it absorbs more heat in direct sun. Overall, this is a super comfortable and versatile tee with great softness and odor resistance, but I think Icebreaker could improve the warm-weather temperature regulation a bit more. Disclaimer: I received this product for free in exchange for my honest review."
