Not as good anymore
neckline is way too tight.. ordered the same size as my previous Icebreaker t-shirts (which I love), but had to return it b/c the neckline was uncomfortably snug.

Great shirt for multi-day use while backpacking. I used it for 3 days and some of my other layers smelled worse than this one at the end of the trip. If it’s really hot, I’d opt for something lighter but this is a great go to for most adventures in Colorado.

Smaller than before
I love this brand and their apparel. Unfortunately these shirts are significantly smaller than the same style ordered a year ago.

Awesome fit
[This review was collected as part of a promotion.] Perfect t shirt for any summer activity and still a great fit to take it from the mountains to the town for some food and drinks. Super breathable and great fit that is not too snug.

Light, quick dry, great odor resistance. Worked well for backpacking in Thailand heat. A bulky tag on the side was a little irritating and not tear away. It’s too early to judge durability yet.

I love Icebreaker products and I love the lightweight, quick-drying properties of this shirt, but the torso is just a little short for an XL. I think this should be at least an inch longer. However, if your torso is short or you're under 6' tall, this might work perfectly for you. One other nitpick is the wad of tags on Icebreaker products I always have to hack off. Do there really need to be that many tags??

Very comfortable for workouts and running. Runs on the smaller side and remember to hang dry only.

Great t-shirt
i used it on a climb to Camp Muir (Mt. Rainier) on a sunny day and it was great, although it got wet I didn't get cold and it dried pretty quickI used it during a climb to Camp Muir (Mt. Rainier) on a sunny day, and it performed well. Although it got wet, I didn't feel cold, and it dried quickly.

Bad sizing
[This review was collected as part of a promotion.] Strangely small for a medium. Maybe it was a misnamed small? I returned it.
