Icebreaker  Merino 260 Tech Long-Sleeve Half-Zip Base Layer Top - Men's

Crisp details with a nice fit and finish. It’s a very attractive base layer that’s at home in the woods or downtown. The fit is between a regular cut and a slim. The garment fits close to my skin without hugging me or interfering with movement. I’m 6’ tall, 175 pounds with a 44” chest and the large fit me perfectly with a little extra room to spare for first wash shrinkage. This is a very stretchy weave and it feels a little less substantial and a little more delicate than the Smartwool 250 gsm. I would have preferred if they had blended in some nylon or polypropylene to toughen it up. I have never liked the feeling of wool against my skin but this is really comfortable to wear. In fact it is the most comfortable top or base layer that I have ever owned. My only real issue is the cheap zipper they chose to use this year. Putting a dollar store zipper on a $120.00 garment is offensive. If this is the beginning of a permanent trend with Icebreakers then this will be the last thing I ever purchase from them.

I bought three of this fine half-zip a year ago. They’re soft and warm, easy to wash and make a good base layer. Most of the time, they’re my outer shirt over a tee from October through April in NW PA. I’m about to order one more.

The fabric is very comfortable to wear without undershirt. You can wear it everyday. Slim fit for athletic men. But the zipper stuck from time to time, they need to upgrade this, i see other pointing out the same flaw.

Love these tops and wish they came in more colors. Can use as a base layer or the only layer in warmer weather. Just as good or better than smart wool.

Gave this as a Christmas gift to my 27 year-old nephew and he was crazy about it. He’s very fit and it looked great on his 6 foot four frame.
