Easy and all-natural active layering comfort

Merino wool fibers are the perfect all-natural solution for keeping you comfortable when working up a sweat in cool weather. Wool is soft, breathable, regulates temperature and its antimicrobial properties control odor. The Icebreaker Women's Long-Sleeve BodyFit 200 Oasis Crew leverages wool's beneficial properties, along with smart design details, to optimize your comfort during cool-weather activities. Flatlock seams eliminate chafing and offset shoulder seams allow room for backpack straps to lay flat on fabric rather than causing uncomfortable seam rubbing. The crew neck and slim fit allow for easy layering and the drop-tail hem provides extra rear coverage for a worry-free fit.

  • Lightweight merino wool
  • Slim fit crewneck long-sleeve
  • Flatlock seams and offset shoulder seams
  • Set-in sleeves
  • Drop-tail hem

Great base layer

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'7"
    Weight: 130 lbs
    Size Purchased: Small

I purchased this BodyFit 200 crew long-sleeve for a six-day backpacking trip in the Sawtooth Mountains of Idaho and wore it every day. Along with a thin fleece, down-filled puffy and winder-breaker shell, I stayed warm on even the coldest nights at 8,500 feet.

I was worried that the wool would be itchy on my sensitive skin, but this top was super-comfy!

I wasn't sure which size to get at first - so I ordered both the small and medium. They both fit my 5'7" 130 lb. frame (34A cup) but I decided to keep the small as it hugged my torso a little tighter - better for easy layering. I returned the medium. Thank you, Backcountry, for making returns easy with the flat $6.99 shipping label!

What is the UPF rating for this shirt?

Hey Carol,

So Icebreaker says that this has a UPF rating of at least 50.

Here is a paragraph directly from Icebreaker:

"Icebreaker merino has a UPF (Ultraviolet Protection Rating) of at least 50, which is considered the ultimate in sun protection. That?s higher than cotton and most synthetics."

Great baselayer

  • Familiarity:I've used it several times
  • Fit:True to size
  • Height: 5'4"
    Weight: 125 lbs
    Size Purchased: XS

I am a huge icebreaker fan and have a couple other of icebreaker shirts (260 weights), this one seems a little less soft than the others but I would still buy again. For some reason the neck is a little tighter too, compared to the same size in other icebreaker shirts I own. For reference, I am 5'4'', 125lbs and I bought an XS. I wear it under other shirts or sweaters so prefer a close fit. Definitely keeps me warm and very quick drying.


Favorite Fall Layer

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

This long sleeve is the perfect addition to an autumn stroll. It provides just enough extra warmth to get me through the occasional wind gusts but if I'm just wearing it as sans jacket, it doesn't create enough heat for me to feel uncomfortable on a hike. With a jacket, this pullover transforms into a toasty baselayer.

The Oasis 200 is lightweight, and fits great. I especially love how soft and stretchy the material is. For sizing reference, I am 5'6''/125 lbs and am very happy in a medium.


High quality layer

  • Familiarity:I've used it several times

This is a great layer for the fall days that go from cool to warm. It has kept me warm, but not caused me to overheat when hiking. The fabric is very soft. I am 5'10" and this shirt is shorter (in the torso and arms) than other base layers, but because I pair it with other items it's been fine.


Ultimate Layer

  • Familiarity:I've put it through the wringer

I recently wore this biking and it was by far the best all-around layer I have ever owned. It kept me nice and cool as I was peddling up hill, and warm and cozy when I was going downhill. I never got too hot and my sweat didn’t freeze on the way down. I didn't even know that was possible! This top is definitely worth the money and SO SOFT! Do yourself a favor and buy one!!


Great long fit

  • Familiarity:I've used it several times

I am quite tall (178cm) and this long sleeve is flattering as well as excellent for moisture wicking and keeping in the warmth. Especially great for a light layer under ski gear. Got a great deal with the on sale colour too!


Improved fit works

  • Familiarity:I've put it through the wringer

I've worn Icebreaker since 2000, when they first started in NZ, and I have all iterations of the Oasis crewe. Last season, according to Icebreaker, they improved the fit on some items, and Oasis crewe was one of them.

And they weren't kidding. The older versions used to have much tighter necks, stiffer fabric, and felt much tighter (like a true base layer). For the new version, neck is a bit bigger, fabric is definitely softer, and fit is more stretchy and just a tad more relaxed - which is a good thing since it doesn't feel as restrictive as before. I can now use the shirt as a baselayer, a l/s over a short sleeve shirt. And since I got the Lotus stripe, the shirt is nice enough to wear in the office, out on a run, and out to dinner, all on the same day. I'd imagine this will come in very handy for traveling.

As always, I wear all my Icebreakers, including Oasis for weeks on end without washing and it doesn't smell. Versatile indeed!


Love Icebreaker

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

I have the Icebreaker BodyFit 260 Tech Crew and got this BodyFit 200 Oasis for my mom for Christmas. The fit is pretty true to size and is extremely comfortable. My mom loves hers and has used it up in the Canadian Rockies and it keeps her warm in the cold but also breathes well in warmer temps.


Great baselayer!

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

Great as a base for cold weather running and cycling! Love how it keeps me warm even once it gets sweaty. Pricey, but I got mine on sale. Also love that it doesn't hold smells- after a sweaty run, I let it air dry and then it's good to wear again! (Great for a college student that hates laundry). I am 5'6", 135 lbs, 32C, and the small fits perfectly. I got it in cruise and the color in person is a little more muted than the picture.

edit as of 11/18/14 still love this shirt but not as durable as i had hoped. starting to get a hole in the sleeve :(


Love this Baselayer!

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

I absolutely love this base layer, it was my first Icebreaker piece and since I got it I have bought 2 more base layer tops and some pants! I am a climber and two of the most important things when climbing is movement and staying warm. I have found this piece works perfect for both. I am 5'4 and 110 lbs, I got an extra small and it is a perfect fit! It is snug to keep me warm but lets me move around when climbing. It is also very soft! Absolutely love Icebreaker!
