Wore this as my base with an Icebreaker Bodyfit260 Altitude on top on a three day 24 mile hike. This combo was excellent in regulating body temp. The weather was around 40-50 during our hikes and this setup kept warm enough for a majority of the time. Never felt clamminess and cold chills. Like you'll read over and over about merino wool, it's great at keeping odors at bay. This is no exception.

Most people when they first start looking a Icebreaker gear cringe at how expensive it is. When you bought that first synthetic shirt, I am sure that you were wondering then exactly how much better could it be than the cotton shirts you had been wearing. Merino wool is next step up, and Icebreaker is top-of-the-line. Yes, it is worth the price, and once you buy one piece of merino gear you will soon find out that it will not be your last!

This is my favorite t-shirt, period. It is softer than your favorite cotton shirt, yet wicks better than your favorite synthetic. Better still, it will not stink like either of them when you get back to camp.

People that are fans of Icebreaker were probably nodding their heads and smiling while they read this review. Do yourself a favor and find out what we are smiling about. :)

This is the last Icebreaker product I will ever buy. First, the tails are never made long enough to stay tucked in during layering – I have if anything a small torso. Second, there is a major shrinkage issue. Labeling claims 5% but my shirts shrunk much more than the five under recommended care. If you ever make the unfortunate mistake of putting your $60 tee in the dryer, kiss it goodbye. I accidentally put one in on low heat and the large turned into a small immediately. I like the feel of Icebreaker wool better but Smartwool is by far a more thought out product – dryer safe, body proportionate. All my wool tees will be Smartwool from this day forward.

I just returned from a backpacking trip in Yosemite where I put this shirt to the test. It was basically the only shirt I wore (I did don a long sleeved Paty Cap3 in the cool morning making breakfast a few times). I hiked 4 straight days in this shirt, and sweated so much it has salt stains! There's salt stains all around the back and on the front of the shoulders where my straps came around. After all that you'd think you could smell this shirt from a hundred yards away! That's not the case though, it doesn't smell at all like sweat or BO!

Aside from it killing odor like an angry team of Navy SEALs, this shirt was super comfy too. You really wouldn't know it was wool unless you read the tag. I did notice that the fabric pilled slightly where my shoulder straps were rubbing on it, but nothing too major. This stuff is so awesome I just picked up a long sleeved shirt from IB for skiing!

Sizing note - 6' 175lbs I went with a L for a comfy (not snug) fit.

I bought this shirt mainly for hiking and working out. The merino doesnt dry as fast as some of the other tech shirts I have, but unlike the other shirts, you could wear the merino for a week straight and it wouldnt stink. The stitching and the material are quality. I am 5 8 150 lbs and I ordered the large. It fits great. I dont think I would pay full price for this shirt but if you can get it on sale, its worth it.

I've loved Icebreaker goods over the years and even my 2007 Hopper was a pleasure to wear in the summertime heat of the Carribean as well as the (relative) chill of the San Francisco winters. But by 2007, the quality of China-produced Icebreaker goods no longer justifies a premium price to me. The zippers, stitching, and general quality of fabric has slipped greatly. That 2007 piece has a hole in it after probably only a couple dozen wearings (and all washing done in a gentle front-loader).

A good value at 30-50% off. Marginal at 20% off.

I'm not paying full price any more.

A buddy and I always try to take some new gear on backpacking trips to see how it works. I wore this shirt continuously for 4 days and 3 nights (80 degrees, 26miles, & 50lbs) without washing it to see how it would do. The answer is AMAZING! It had some mild odor to it---but I kept it on for the car ride home even though I had planned to change. I'd say it smelled similar or better than a synthetic after 2 hours of hiking, or a round of golf.
My buddy accidentally dropped his in the rapids at dusk trying to wash it, and we found it plastered to a rock downstream the next morning---no tears, stretches or anything. Smelled a little like algae, but dried it out and it was ready for more.
The bottom line----if you are like me and stink up a synthetic in about 2 hours you will ABSOLUTELY LOVE this product----and find the $ well spent. If quick drying is your main concern---the synthetics are faster. So far I think the IB shirts are more durable also--They seem to pill a little bit in friction areas from the pack, but this is mild and to this point barely noticeable. Nothing like the pulls you get with the synthetics.
The best review is this---I started with one for backpacking, and bought several more for casual use b/c they fit/hang/feel nicely.

My girlfriend is definitely sick of hearing the angels sing every time I pull this shirt out of my drawer. The most comfortable shirt I've ever owned. Paid full price (at the time around $70) and didn't regret it even for a second. I am a huge proponent of Merino wool and own several different Merino wool products. Icebreaker Merino wool is definitely the best quality. Very stylish too. So quit complaining about how expensive Icebreaker costs and see for yourself.

I've found this to be a very nice shirt, but not worth the premium over the other two wicking tshirts I bought here recently: the Mountain Hardware Wicked Tech T-shirt and the North Face VaporWick Ruckus T-shirt. You can buy two of them for one of these and I think that they dry faster than this t-shirt and are equally comfortable.
