Here's what others have to say...

Doe si shrink at all when you wash it. Also I have tried Icebreakers body fit 200 and Im sorry maybe my skin is more sensitive maybe it itches less than regular wool but there is a slight itch or maybe I shuld say abrasion even though it feels smooth. I wonder if I was it it might get less abrasive any body can fill me in Id appreciate it

Definitely shrank a bit when I dried it with heat. Realized that mistake after the fact and now I just wash it and then hang dry. My skin might not be as sensitive as yours I did not feel anymore abrasiveness or itchiness after washing.


Don't order if tall

    Way too short in torso. A little too short in the sleeves (bought XL).
    Why they decided to make the torso way shorter on this vs. the Icebreaker BodyFit 150-Ultralite Anatomica Crew - Short-Sleeve (whose torso in XL fits me nicely), I'll never know. Thumbs down.
    For reference I'm 6'5", 208lbs, athletic build.

    To: ME - From: ME

    • Gender:Male
    • Familiarity:I've used it several times
    • Fit:True to size

    My wife is a terrible gift giver. I on the other hand - to put it mildly - I total ROCK at giving gifts. Ipad Mini, Patagonia (or is it Patagucci), babies (easy to get, hard to return) - really the list could go on for a while. Meanwhile I get wal-mart tube socks - FROM HER MOM. This is not intended to be a low blow - she has other redeeming qualities. However, it did mean that in order to save my Christmas this year I had to take matters into my own hands. If I wanted a good gift - well then, dang it, I had to take some of my own gift giving magic and just sprinkle it on me. And again - not to be vain - I hit another home run.

    Okay I will admit, wrapping my own present on Christmas eve was a bit cheesy - I should have been more diligent and wrapped it a few days earlier to let the suspense build. But none the less, I was more than happy to open my box bright and early, as my kids (one of my awesome gifts to my wife) opened their Legos, barbeis, and other great gifts from me. After making a bit of a scene thanking myself, I put the shirt on and immediately noticed the temperature regulating qualities. The icy stares the wife sent my way barely even registered as I was in wrapped in 'Bodyfit 200 merino wool' bliss.

    Since that magical Christmas morn, I have used the shirt as a layer under thin button up work shirts as well as a layer under softshells while ice-climbing. It is nice under a thin button up shirt when the weather is cold as I can run outside on those brief errands that pop up during a work day without having to grab a jacket (except for when it is windy - wind blows - gotta wear a jacket when it's windy). As a base layer while ice-climbing it is pure joy. We have had some cold snaps lately and day time highs were sub 20's. However, between this shirt and a nice softshell jacket, I have been totally warm while climbing. I do have to throw on a puffy while belaying but whatevs, try standing around, not moving, in the cold and stay warm - not an easy task. As for fit, I am 5'9", 175 lbs and the large worked out perfect for me. So seriously. If you ever need some gift giving magic for yourself or anyone else take it from a gift giving PRO - this shirt rocks.


    not for bigger guys

    • Familiarity:I've put it through the wringer
    • Fit:Runs small

    very thin, very tight fitting in XL

    beck lie is almost "plunging v neck "

    way too small cut for guys with square shoulders like all ice breaker gear . if ur like me, id stay clear. look at the models they use to ilustrate what kind of guys shud buy this stuff.

    althouhg its lovely on the skin its just a bad bad fit

    Icebreaker comes in a few different "fits". Anything with "bodyfit" is meant to fit pretty snug and stretchy, mostly as a base layer. 3rd party sites like or REI rarely distinguish this :-/. Some of IB's thicker stuff has a different fit, and you may have more luck with that.


    Comfortable, warm, base layer

    • Familiarity:I've put it through the wringer
    • Fit:Runs small

    I have never owned such a comfortable shirt. This is especially important for an item of clothing that I find myself grateful for in desperate times. I will use this for my base layer when I backpack, a toasty layer to stow away on my fall climbs, or just something nice and warm to wear for the night out. For me the fit is 98% there, but a medium proves to be just a tad short in the arms and torso. Keep in mind that I am 6'3" and finding clothes that fit 100% perfect is very rare. Even with this I plan on keeping the shirt, too comfy.


    Couple days strong

    • Familiarity:I've used it several times
    • Fit:True to size

    purchased the 200 to wear under my puffy as an every day shirt as well as a layering piece on the mountain. Haven't got the chance to wear to the mountain but just in the city I've noticed this thing performs! On a 25-30 degree night, I wore this under my 550fill puffy and was very comfortable. Having this on under my puffy inside got me sweating. Not to be gross but I've used it 3 days in a row now and it still smells new! I'm also 6'1 165-170lbs and the large fits great


    Top Notch!

    • Familiarity:I've used it once or twice and have initial impressions
    • Fit:True to size

    The bodyfit 200 oasis crew is a fantastic base layer. I got mine in a medium, which was a true fit. I used it first time on the river this week. It was about 30 degrees and snowing - So, between this, my puff and a shell I was toasty warm the entire time. The merino wool is real soft and did a great job keeping me warm and dry. I stayed out for a few hours with no problem. Call me gross but I'll use it a couple more times before washing, as it doesn't stink at all. Another plus of merino wool.


    Normal Icebreaker Fit...

      If this fits your right, then you'll give it 5 stars. it's made with high quality merino; it's got a durable but soft feel. And if you've ever used merino wool, you know it's hard to make it stank and it keeps you dry.

      However, as a climber i have larger forearms and Icebreaker's cut is tighter than other brands. they also have longer arms that lead to some bunching, and shorter waist lines that encourage them to become untucked. I don't fall in a standard set of dimensions, so maybe this works great for most, but other brands fit me great.


      New fit for F13!
