200 Oasis LS Crew Top
The dead of winter brings bone-chilling temperatures that make it uncomfortable to ski or ride in, and the peak of summer brings soaring temperatures that make it tough to leave your air-conditioned home. Designed for shoulder season adventures and mild winter temperatures, the Icebreaker Men's BodyFit 200 Oasis Crew thrives in the kind of conditions you enjoy the most. This top features Icebreaker's 200-weight fabric, making it a lightweight alternative to its midweight baselayers and better suited for the cool-to-cold conditions you'll encounter during fall trail runs, spring ski days, and sunny showshoe hikes.

Love that I can wear as a base layer or as a stand alone

Wool for the win
I’ve taken this shirt on a couple bike tours and it is awesome. Keeps you warm in the cold, but breathes well when it gets warmer. Doesn’t stink, even when you do. Even used it whitewater rafting on a cool morning. Got a little loose when soaked, but still worked well.

Highly recommended
The athletic cut fit is excellent. Warmth is what you would expect for a midweight baselayer. Packs down well for bike trips.

[This review was collected as part of a promotion.] I am new to hiking and have used this base layer for hikes in the heat and the cold and both have been amazing! I will definitely be getting more for future adventures. Highly recommend.

Excellent customer
[This review was collected as part of a promotion.] Bought on winter sale but didn't open until spring. Was shorter in torso than other bought same time. So on phone wonderful woman was able to find way to return to replace. Went off perfectly. Replacement fits perfect and wore today chilly weather midwestern college town bicycling.

Comfy
[This review was collected as part of a promotion.] Woman here, I bought a men's size small because I was shopping clearance and didn't love the remaining women's colors left in stock. This men's long sleeve fits me nicely, a little loose but in a comfy way. My go-to merino camp shirt (different brand) developed so many mini holes and darned patches I was looking for a replacement for when I don't want to look so scrappy. This icebreaker shirt is soft, cozy, quick drying and overall great so far. We'll see how it holds up to years of abuse backpacking. If I had one complaint at this point, the tags on the hip are ridiculously long, I don't see why anyone wouldn't cut them off.

I absolutely love this product, wear it all the time not only as a base layer, very comfortable and versatile, you have to size up for 200 midweight.

Merino wool at its best
I have so many Icebreaker articles of clothing because I love their products. I have base layers (top and bottom) and mid layers. All of them have performed very well in the trial period while I am hiking and biking my local trails. The ultimate test is when I take them on my treks to Africa and climb and summit Mount Kilimanjaro in March of 2025. I will update my review after my trip. I am certain that they will perform very well. Icebreaker merino is awesome. They performed flawlessly while climbing and summiting Kilimanjaro.

Great mid weight base layer
- Familiarity:
- I've used it several times
I wore this and the matching pants to sleep when camping in Florida. Warm enough in 40 degrees, breathable enough in 70 degrees, and thick enough to keep mosquitoes from biting.
