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.

I wear these shirts literally every day

[This review was collected as part of a promotion.] I wear these shirts every day. So comfy. Perfect when hot. Perfect when cold. Even with heavy use, I get many years out of them before they break down.

Go-to merino brand.

Always a quality product, I’ve worn out dozens of sets of merinos- these are by far the best value

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.

Rookie approved

[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.

warmth, no scratching and no stink

shirt is very comfortable and gives just the right amount of warmth for cross country skiing. Also seems to be stink resistant

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.
