This is my first piece of 100% merino, and I wish I never bought it. I absolutely love it and want more, but can't dump 50 or 60 bucks a pop on t-shirts. I was much better off not knowing what I was missing. Damn you, Icebreaker!

I'll start here: I love this shirt!

I like the way it fits, not being too wide at he bottom, and it is extremely comfortable. As with most marino wool products, the wicking is awesome, and the odor is very low, so you can wear it a while in the backcountry without being too offensive.

I really appreciate the way it wears well in most conditions. It's a very versatile shirt, and it is tough enough to take a beating. It's not right for extreme heat, so look elsewhere if that's the kind of shirt you need. However, if you want a highly functional shirt for most weather, that looks good, and that can be used as a base layer in colder conditions, this is a good purchase.

This shirt just feels so good. It is a lightweight so it's not going to cut it when it's cold, but that's understood. It's great for warmer weather or layering during the cooler months. Love it!

Great shirt for spring skiing, running, hiking, and even just casual wear. It's pretty soft, but not nearly as soft as the 200 (which I'd say is a bit more versatile). This shirt isn't very warm, but its very good as a baselayer underneath some layers. Merino Wool is the best!!

My new favorite outdoor shirt! Unlike the rest of my icebreaker stuff, this one smells a little funky. Must have come from a defective sheep.

This is my favorite shirt for warm weather activities. The wool is amazing against your skin and the shirts looks great. They fit like a normal t-shirt, so you can wear it by itself in public (even if you aren't ripped). I have the long sleeve shirt as well and wear them pretty much every time I hit the outdoors when its over 50 degrees.
My only gripe is that they don't come in white! (I wear them as undershirts to work also, but can only wear with dark shirts due to the lack of lighter colors)

I own a few 150g Smartwool and Icebreaker Merino wool shirts.
I prefer the athletic cut of Icebreaker vs the more relaxed Smartwool shirts.
Merino breathes and wicks like no other material out there.
I use Merino wool for every occasion and it's truly amazing.
I really like the Tech Lite's subtle design. People hardly notice you wearing the same shirt multiple days in a row.
Only negative, I feel it might be "too fine" and I'm worries about the longevity of the material.
I personally like the 200g better. The 150g is also more relaxed than the 200g.
6ft 135lbs, Medium fits a bit baggy for my tastes.

I wore it for a week straight and it truly did not stink. Very light, feels very smooth. Like butter. I will buy another when it wears out or if I see one on SAC.

I love this shirt. It has nice t-shirt cut to it. I have other Icebreaker BodyFit style shirts that fit very close. This one is more relaxed, looks and feels great. Excellent for running in the heat.

This shirt is great. I was hesitant about spending the $$$ on tee, but it's a performance tee. Did back to back runs of 14 and 15 iles and the shirt didn't have any odor. The shirt performed well in temperature range of 50 to 80 degreees. Haven't tested in the Texas heat yet, but it's definitely worth the money. A few of these is all you need.

6' 215, should have ordered the XXL since there's good amount of shrinkage. It's a cool (not hot) shirt, good wicking, but for $60 just not for me.

Smooth fabric and nice enough to wear casually or when working out. I like the more relaxed cut on this shirt than the cut of the BodyFit shirts.

I think my husband now has this shirt in every color available. Every other shirt in his closet is pushed back in the corner and doesn't get worn. Merino wool is hands down the best thing out there for breathability and wicking & makes anything cotton feel terrible. So if you are purchasing this for the first time you better save up for your new merino wardrobe; you wont want anything else. (He also will only wear merino socks and undies--spoiled for life.)

Great shirt. Soft, comfortable, stylish, and you can wear it every day.

Great comfortable good looking soft shirt. One huge downfall is that it is way too long. Only if you are really tall and skinny should you get this shirt

He really liked the shirt!

I own 4 of these shirts---I loved them---they seemed perfect in every way, just like most of the other reviewers. Comfy, no-stink, quick drying, etc. Here's the flaw: within less than one year of frequent wear the first shirt I bought has started to die---the fabric is developing holes all, first at points of more friction, but now they are showing up all over the shirt. The second shirt I bought (a couple of months later) is now following the same pattern of fabric failure. For a shirt this expensive I was hoping for more durability. So now I have to be careful and save the shirts for travel. In short, don't expect these shirts to hold up for long!

yes it works with everything, all temperatures, may be a little on the warm side, but still love it

This is my first icebreaker with many more in the future. Agreed it's a little pricey but the stink free workouts are worth it. I no longer worry about having to get in the elevator with one of my neighbors after a run. Bottom line this is the best workout shirt I've ever owned.

I purchased one of these last year, for wearing on my 10 mile (each way) bike commute to/from work. I also purchased a few biking jerseys at the same time. The jerseys are at the bottom of the pile and I have since purchased 4 more of these shirts. I wear them on all my climbs as my base layer.

Yes, they are expensive. But they are worth it. I can wear one for days in the backcountry, a feat I won't subject my climbing partners to with any other fabric. Wash them in woolite and turn them inside out before washing. To dry, I let our dining room chairs each wear one.

I bought two of these to alternate using while trekking 8 days over the Ouachita National Forest. They are lightweight, ultra-comfortable, and they do not hold odor; at least not until after a long time being used. Mine never picked up my odor after eight tough days in the field. I definitely recommend this shirt!

I like this as a base layer or by itself on warm days. It does get a bit itchy under pack shoulder straps, and the stitching under the arms causes it to bunch funny under other layers. I like that it's not so tight it can be worn as a casual shirt too.

This was my first Icebreaker product & I have since added more. It is a great quality of wool that is extremely comfortable & not an itchy fiber in sight. Warm, nice fit, good looking. Solid wardrobe staple for a day about town, or a trip to the gym. Since wool doesn't retain odors like synthetics, you'll remain stench free well in to the future.

Awesome shirt. Gave it as gift to BIL and he loved it, however, we did have it "giftwrapped' in a goatskin bag. BUT, the bag came with the shirt and not in the shirt, not sure if I would do that again. LOve the idea of reusable gift packaging but loses effect if not packaged IN the bag. But shirt rocks.

I'm a merino wool convert vs. technical/performance fabrics and am trying to convince my husband of wool's benefits with this T.

He loves the feel, fit, and performance. Dries quickly and doesn't retain odor.

Because he likes a looser fit, I did purchase an XXL versus his traditional XL. Now I'd like to find more at a sale price.

I wear this gear every day, best invention ever.

See review title.

As others have said this shirt will stink very litle when sweating.I ilke the feel of the cloth on my skin. I wear my shirts day and night.After buying this shirt 2 years ago I have bought 3 other shirts and 3 pairs of socks because I think Icebreaker is wonderful stuff. The reason I gave 4 stars instead of 5 is because after a year+ my first shirt developed little holes in about 3 places so the fabric is not so tough as some other fabrics in my experience. Secondly, I found my dark blue shirt faded to a purplish colour I do not like.Yet I recently bought more Icebreaker goods because even though they are very expensive and not so tough and prone to fading i still will not stop wearing Icebreaker goods...NOTE: on two of my other model shirts the tags sewed inside at the left sides had to be cut out by me as they were sharp-edged and scratching my skin too much..The T-shirt above has no such annoying tags.

I first bought a Patagonia Capilene T-Shirt...it dried very, very quickly, but it would smell awful. Then I bought this shirt and it doesn't smell, but it doesn't dry nearly as fast as the Capilene shirt. I did find this shirt scratchy the first time I wore it, however, after the first wash it was better.

I have problems w/ sweaty t shirts. Any synthetic material never gets clean. I've had an icebreaker for a year and loved it. So much so that I bought 2 more. I am a wool convert. I even started to switch my cycling jerseys to wool.

I LOVE these shirts! So comfortable and super functional. it dries quickly and does a great job of regulating your temp and keeping you comfortable.
Bought two of them and wore them on 12 day backpacking trip to West Coast Trail- slept in them(kept me from sweating in the sleeping bag) hiked in them(kept me from getting overheated on the trail), Layer well and kept me warm on the cool nights camped on the beach, live in them at home and they do not stink no matter how hard you work!! They wash/launder well on delicate- no problems- air dry and good as new!
Good buy and good product! I recommend highly!

I took a gamble on the blue one. Glad I did. Not only was it cheaper, but it is much darker as well. It's not that bright neon in the pic, it's a much more subtle tone. I'm 6'0, 185lbs, and the large fits pretty slim.

Light, soft, and looks good. Not only does this shirt wick moisture extremely well, it won't start to smell for days! I'm 5'8", 160 lbs and the medium fits perfectly (a little big at first, shrinks down to the perfect size). As soon as I get more money, I'm buying the other 5 colors.

Icebreaker's sizing is inconsistent. I am wearing a newly purchased shirt in Medium that fits exactly the same as a Small I bought last year...yet another Medium I tried on was bigger.(I haven't changed size and all my other clothes fit the same including the old shirt.) I have found this to be the case in their boxers too. You cannot trust the size charts or labels anymore. I don't have any faith in their quality control at this point. I think the China outsourcing is biting them in the butt.

great t-shirt - light very comfortable and most importantly breathes - Just came back from the Caribbean and this perfect for those hot evenings

love this shirt, very comfortable.

Warm or Cool weather....it did not matter........this shirt was comfortable to wear....a little on the expensive side.

The first thing you need to do is get over the sticker shock - my experience has been that whenever gear has the word "tech" or "technical" in the title, it will be expensive - and also worth it. I travel a lot - between 50,000 and 100,000 air miles a year and only use carry on luggage. The Superfine 140 Tech T works equally well in warm or cold weather, takes up minimal room in my carry-on bag, and easily launders in my hotel sink and is line dry by the next morning - and it does not smell in between washings. My advice is get two, carefully alternate them, and if you are a minimalist like me you will not need any other undershirt-type apparel.

"You payed that for a T Shirt?!?" asked my wife. True, there is a little sticker shock, and yes, on first wear it feels like it's made of steel wool. But after a good wash or two it felt great. Kept me nice and warm on a poorly-planned mountain bike outing in a downpour, and I didn't smell like poop afterwards. Stink power is much better than capilene. Just buy one and try it out.

It's been eight years since I brought back my first Icebreaker T-shirt from New Zealand ... and I've still got it and I still use it. The size has shrunk slightly with all the laundries but that is as advertised.
This new one has a slightly looser fit (which I don't like so much, actually, thus only 4 stars) but the lighter quality makes it suitable for warmer conditions (which I like). Comfy to wear and does not smell -- GREAT.

Wow. This shirt is amazing. I have many wicking shirts. What intrigued me about the merino wool was the ability to prevent body odor from clinging to it. I immediately put this to the test and did about 7 mountain bike rides without a wash. While most baselayers could kill a cockroach they smell so bad, this one maintained only a slight odor. Way better than other baselayers that can smell so bad I lose friends and potential dates. The shirt wicked well and was comfortable. Now I don't have to smell horrible when I go into the bar for that post ride beer. Awesome!

This is my first icebreaker shirt and I could not be happier with it. I was a little skeptical to buy a wool shirt to wear in the spring/summer months but i have been very pleasantly surprised. This shirt is super lightweight and breathable, I wore it for a whole weekend camping, hiking and climbing and never got too hot or too cold. It did a great job of temperature regulating and wicking away moisture. This is an excellent shirt! Definitely check it out!

Not sure I will ever be able to wear cotton or poly again. This has to be the most comfortable shirt you can wear. Looking forward to wearing this for everything from lounging to running.

I LOVE this shirt. it is so comfortable and super functional. it dries quickly and does a great job of regulating your temp and keeping you comfortable. it's a little fragile, but mostly in the washer. I have a few little holes from the washing machine. I would recommend with any washable wool that you wash it in a pillow case or mesh laundry bag, just to keep it safe. I also don't wash mine very much. I just hang it up and let it air out. It's usually good to go in a few hours

Returned product as it was not near as comfortable as comparable smartwool. Possibly would have softened after a few washings.
