Icebreaker Sport320 Rock Zip Shirt - Long Sleeve - Men's

This shirt is now a staple of my outdoors wardrobe. I've worn this in the mountains of Utah ski touring and hiking in the Adirondacks of NY. In both climates, this shirt kept me warm and dry. It's soft, highly breathable, odor-resistant and very very comfortable. Highly recommended.

Great shirt. Warm, wicks sweat, looks good, feels comfortable. Sometimes I find it too warm, and it's heavy. Otherwise, I really love it.

Perfect shirt for midlayer skiing in the winter or base/only layer while hiking in the high elevation in summer. Would get perfect 5 stars except it's so expensive. If you like this shirt try the Icebreaker base layers which are amazing.

And you know the best stuff is. Merino and Icebreaker in particular is unbeatable when it comes to regulating your body temp, being soft on your skin and not making you stinky. This shirt is a bit thick for ski touring unless it's really cold but when the temp drops it's the cats pjs.

These products work...a new standard in undergarments. Substantial fabric, less static (less pet hair sticks to it), less odor, less pilling, good zippers, thumb hole, great wicking, quick drying, comfortable against the skin.

This is one of the best mid layers I own, it's warm, stylish, and the collar doesn't pop too high to make your Adam's Apple uncomfortable. It's also very very warm and can also be warn along in warmer days. Thumbs up again Icebreaker.

Very warm and soft as mid-layer, feels slightly itchy as base layer.I will recommend it to my friends.

I've been really pleased with this sweater. Like others have noted, it really covers a wide range of temperatures and conditions. I wore it kayaking on a 70-degree day in March, and was perfectly comfortable. It's a ski staple, and is warm on the slopes (under a shell) and not too warm in the lodge. I've washed mine several times; lay it flat to dry. It shows a very minor amount of piling. It's enough that it's not quite as crisp as new, but not enough to stop me from wearing it to work in the winter.

fantastic, easy to maintain, held up against wind and cold, and yet not too hot when the spring days heated up at Tahoe, this is an easy way to layer and quality is excellent

great, great, great. Great shirt, great wool, great feeling.

This is an great midl ayer garment. What I like most about it is that the fit around the neck loose and not the least bit tight. I hate outdoor clothes that is constricting around the neck! The best part of the garment is the merino wool, which does not seem to become freezing when your activity level decreases. One not of caution: I have had a few other Icebreaker garment develop holes or rips along the seems. They were exchange without any problem. So keep your receipt

Just what you'd expect from a $100 wool top. Nice for layering, well made, looks good, heavier that synthetic but 100 times better smelling for actual backpacking. I wonder how well they wear with long term use as an outer layer- with backpack abrasion for instance?

I prefer natural fibers to synthetics every day of the week. This shirt is the best base layer I've ever found. Great to wear around town and in the mountains. This is a very very very soft shirt. I absolutely love it and own a lot more Icebreaker shirts. Check out Ibex Merino Wool as well. It's not as soft to the touch, but has a different more Earthy style. Both brands fill my winter closet.

After purchasing a couple of pieces of Icebreaker for my wife, I ended up buying one for myself...the Rock Zip. Needless to say, I now own about six Icebreaker pieces and my wife owns about eight. I can't say enough about the product, it's warm when it needs to be, cool when it requires it, doesn't stink (and let me tell you how great that is!), I haven't had an issue with any shrinkage, but then I wash cold and hang dry just to avoid the possibility. Buy Icebreaker, your wallet will thank you in the long-run!

This is one amazing mid-layer. Extremely comfortable, warm, stylish...it is my new favorite piece of gear. Most other brands don't fit me well, as I am fairly tall and have a long torso. This fits perfectly. No belly-button showing here. Just don't tumble dry it.

Icebreaker is the perfect clothing for anyone who moves in the outdoors. I wore a single lightweight long sleeve shirt for a week long mountain biking trip from Telluride to Moab, and it kept me comfortable in temperatures from 50-90F, blocked the sun, and didn't hold any odor for the entire week! The Rock Zip does the exact same thing in a slightly different temperature range. 30-65F, depending on how you layer. I carry less clothing on multi-days than ever, because two layers of Icebreaker and a shell cover such a wide range of conditions. I gave away all my miracle fabrics two years ago and will never wear them again.

I purchased one at the beginning of last year's season and found it to be the warmest top I have. It is even warm when wet. I bought a second one mid season because I was so impressed. The second one shrank in the wash (the first did not). Ideally do not dry in a machine, but what are you going to do on travel?

I just love this. It's really warm,really soft,and great colors. I need more of these.

Having tried synthetics as mid layers for a number of years it is obvious to me that icebreaker clothing is better by far. It does not "stink" after hard use, it breathes, it insulates and best of all its machine washable. Its great for the environment too! (Editor's Note: But not machine dryable. Don't put wool gear in tumble dryers!)

Simply put Icebreaker rocks! I have over 10 pieces of Icebreaker clothing and love them all. NZ merino wool is the best available and outperforms any synthetic 10 to 1. No stink, warm when wet, wear numerous times w/o washing, less bulk more warmth, warm in winter cool in summer. I could go on and on but you really have to try the NEW wool to believe me.

Good stuff. Nice weight wool, well put together and I love that it never gets stinky like synthetics. Only wish the fit was a little closer to the body so it wouldn't shift around so much when running, cycling, etc.

I gave the Icebreaker to a friend for Christmas, and he has hardly taken it off since. The weather in New England has been brutal this year, and he wears it on the coldest days. He says it keeps him extremely warm, and it is comfortable to wear as a bottom or middle layer. (And even though he wears it many times a week, it has yet to get a stink to it.) It looks good, is super-soft, and seems to be a pleasure to wear. I will be asking for one myself soon.
