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

Strangely small for a medium. Maybe it was a misnamed small? I returned it.
