My favorite shirt
I love these shirts. I wear them all the time and they are dressy enough that I can wear them to work (casual dress office). They work as a standalone shirt in mild weather and are perfect as under layers when it gets colder outside. I have several and they don't pill or look raggedy even after several washings. I'm 5'2", athletic build and the small is a perfect fit. Not too tight and not baggy.

Very itchy and stiff
I've been wearing Icebreaker since they first came to the US in the early 2000's, and the sis the first time I've had an issue. I've literally worn out the majority of my pieces but this was different. Within a month it became stiff, itchy, and extremely uncomfortable. Absolutely not what I would expect from Icebreaker. Perhaps there was a fiber treatment that went wrong? Or the quality has just declined that much?

Perfect for Fall and Spring, Winter as base layer
[This review was collected as part of a promotion.] It's beautiful, warm and functional! Had to return a Large, which I usually wear, for a Med to get a nice base layer fit.

This is my sixth Merino 260 tech long sleeve half zip therma
[This review was collected as part of a promotion.] I love this Icebreaker top ... I buy a new one every year, they stay in excellent condition year after year I wear them every single day in the fall & winter hiking in New Mexico or traveling too far off lands like New Zealand, Iceland, Norway There's nothing better for comfort and warmth whether you're wearing it during the day out having fun in the winter Wonderland or at night sleeping in your camper van

I have several of these shirts
[This review was collected as part of a promotion.] I wear this shirt or the ones I have like it in other colors almost every day except in the summer. They layer when it's cold, and are comfortable on their own in spring and fall. Because they're 100% merino they don't smell even after a week of wear. They do have to be cold water washed and hung to dry. My others are black, gray and navy, so I like having one that's more colorful, but not at all garish.
