Icebreaker BodyFit200 Oasis Crew - Men's

Love It! This shirt is snug and comfortable breaths like no other performance shirt I own. Other shirts claim to 'wick' the sweat away from your body but the Icebreaker shirts do. The sweat will hold on the shirt but it wont feel soaked, just slightly damp. I have used this thing for 5 trail runs and still haven't washed it, it smells the same as if I just got done putting it through the wash and it dries pretty fast.

I'm 6'1 180 lbs and L fits great. Wicks sweat, stays warm, is way comfortable, and is a fantastic under layer even in cold (10-20 F) and windy conditions. I recommend it - I'm going to buy multiple.

I love this shirt as a layer for all outdoor hiking and camping activities--whether it is a spring day or an cool summer night or the base layer in a stoic but slim system fighting the cold of MN winter. The stretch of the material keeps the shirt against your skin for good wicking and the material is very soft, but I have two caveats. One is that the neck is somewhat large. I do have a bit of a slimmer neck, but it feels like the larger neck defeats the effective heat regulating nature of the merino wool. The second warning is that although soft, be CAREFUL when using this as a base layer for cool/cold running. I thought it wouldn't be a problem, and certainly better than cotton, but my nips took an absolute beating on an 8 mile run with this shirt as a base layer. So while awesome for most things, merino does have some limitations.

I own several different wool and synthetic base layer shirts and this one is hands down the best. It never smells and doesn't itch. Something I haven't been able to figure out is some of my other base layers have problems if you wear antiperspirant with them and it never comes out of the shirt - not so with this one. Not sure if it's the material or the fit not riding into your pits. If I ever see this shirt go on sale again I will buy a ton of them for all my friends and family (and to have a backup or two in case I damage mine or it's dirty).

Excellent lightweight wool shirt. my bf takes this backcountry skiing all the time and it dries extremely fast even when soaking wet. buy a size up, though

Bought this for a elk hunt this fall. Was highly rated by friends. Nice light weight wool shirt. Quality construction and good fit.

This shirt is awesome! I guess that is why I now own three of them in different colours. I'm 6'1", 188 lbs and the large fits great. It has slightly longer sleeves and body than most of my shirts, so someone who is 6'2" and around 190 lbs could easily get away wearing the large. There is no shrinkage with washing as long as you hang dry. It does fit snug against the skin, which works great for a wicking layer. This shirt is surprisingly warm when needed, and doesn't seem too hot when the weather warms up. The merino feels very soft. There are no seams under the armpit which is great for runners. Go buy this shirt!

I love this top. I used it mainly for multiday hiking trips for use at night but it also came in handy for those colder days of hiking. It retained its tight fitting shape and refused to stink even after being thoroughly soaked in sweat. The best thing was though that it felt so nice and and the long sleeves were actually long and didnt leave my wrists exposed. The only minor drawback with it is that it has started to pill on the back where a backpack rubs but this only affects appearance and not the ability to keep me warm. I am never going back to poly thermals.

Start wearing these and you'll want to get rid of all your poly. I did.

I discovered Icebreaker while visiting New Zealand and the locals raved about it. I picked up a few pieces of Icerbeaker while "down under" and have been stocking here through Backcountry.com ever since. I am in love with the light wool shirts, in that they make great undershirts, t-shirts, and in particular gym shirts. They are soft, always comfortable, and wick sweat very well for exercising. It is true, they don't seem to absorb sweat and smell the way cotton shifts or some synthetics do. My girlfriend is particularly fond of the long-sleeve shirts to wear at nighttime, and they seem to make her very happy (and cuddly) - something we both like!

Wore the Icebreaker Oasis Crew with a heavier weight Icebreaker crew over it for seven days of Heli-skiing in 15 to 25 degree weather. That and a great Gore Tex soft shell from North face were perfect. Wearing another layer on the day I thought it was too cold made me sweat too much. I now wear only wool light layers skiing. It only smells when it gets wet for a few minutes. Definitely unzip vents or in the copter zip down jacket so you do not overheat. Then zip back up when you go out and everything is fine.

I've worn this baselayer in cool, wet and warm , dry conditions and it hasn't failed me yet. The merino wool is soft, comfortable and incredibly warm yet light and airy. This will become a "must take" piece of clothing on all backcountry trips. Try it, I bet you won't be disappointed.

Merino wool is great stuff! This top is light, close fitting, soft, and regulates your temperature nicely. It's not as tight as Under Armour (at least not on me I'm 6'-1, 165 lbs) but is still easily layered. Put this under a midweight fleece or windbreaker, you'll love it. I use it for snow sports, hiking, and fishing. I have not been let down. Ice Breaker makes a very nice product.

This Oasis Crew (weight 200, lightweight) is incredibly comfortable and useful. Works in the winter by itself indoors (can keep the house cool and save $$) or outdoors as a first layer. In warmer months, still comfortable by itself although I doubt I would don it if temps soared over 90ºF. You hardly know this piece of clothing is on except for the fact that you are nice and comfortable.

B.O. is no longer an issue. Just shake it out for a few seconds before putting it back on, (assuming the stink was washed off the armpits) there will be no stink on the shirt. Its amazing.

I bought this for my father for a long ski week-end and he loves it - he wore it all week-end.

This has got to be the best winter running shirt I have ever had. I have worn it in weather down to 0 degrees as a base layer and alone in weather around the 25-40 degree mark. It breathes well, and the moisture wicking fabric is awesome. I use it to run in, and it has been excellent.

If your looking for light weight yet warmth and comfort this is the shirt for you! Hands down best fit Merino Wool shirt out there!!

Got this to replace my old worn out Royal Robbins base layer. This shirt is awesome at regulating temperature, and wicking away moisture. The no stink quality is also great - great value and worth the purchase for sure!

This is part of my first set of icebreakers I have owned and totally love them! New favorite!

Here is the email that I got from my dad. I gave him this shirt for his birthday. He is a marathon runner in Chicago. "I ran this morning with the new shirt you gave me. LOVE IT! The temp was 40 degrees and the shirt performed stunningly. Amazingly I didn’t need a vest or jacket or any other layers! My body stayed the perfect temp, while running and even after. (usually my dri fit type shirts get really cold and clammy when I stop.) Oh, and did I mention that it’s extremely comfortable! So soft and form fitting."

I was looking for the underwear besides of Patagonia. I felt the cold while wearing Patagonia, which was always damp with sweat when I stood on a peak while trail running. However, after wearing IceBreaker, I did not feel such cold once. It is a fiber which has not shrunk even if it washes violently with a washing machine. The form fits the body very much. It is the best for running a mountain in a cold season.

Who would have thought that one could wear wool in the heat of the summer and be comfortable? I used this merino wool top on a 4-day excursion into the eastern High Sierras above 10,000 feet. The sun was warm and the air temp was in the mid 80's even at altitude, but this top kept me comfortable, absorbed the sweat and was relatively sun protective. What really impressed me was that I did not stink after wearing this top day and night for 4 days. A further benefit occurred each time I hit a pass and wind picked up. I would don my Patagonia Dragonfly Windshirt, and, between the Oasis top and the windshirt, I was able to stay warm and avoid the wind chill factor. I am sold on wearing wool even in the summer, especially in the Sierras.

I've worn this crew on Southern California desert hikes, in the gym, as a night shirt, around town, and as a base layer downhill skiing in Colorado. It feels great, dries almost as fast as poly, and stays odor-free. The ingenious sewing pattern completely avoids any under-arm seams, so there's no chance of chafing.

I bought a Icebreaker Wingzip on a trip to Oz a few years back. Though it cost me nearly as much as my belay jacket, I have been VERY thankful I got it. I broke down and bought an Oasis Crew and another Wingzip this year. The Oasis seems even softer than the heavier shirt, yet gives a lot of warmth for the weight. The hype about wool not stinking is so true, and this quality is wonderful!
