200 Oasis 1/2-Zip Top

The Icebreaker Men's BodyFit 200 Oasis Zip-Neck Top is a lightweight baselayer for cruising around the slopes. Its merino wool fabric regulates your body temperature so you're neither too warm nor too cold, and you can zip down the collar for a little air when your ride gets intense. The Oasis also stays fresh after multiple uses, making this baselayer an intricate part of your attire when you head down to Chile for a skiing adventure. Flatlock seams prevent uncomfortable chafing against other layers, and they're offset on the shoulders to keep you comfy when you have a backpack on. A drop-tail hem increases coverage.


  • A lightweight wool baselayer top for active wear in cold weather
  • Merino wool is warm and breathable to regulate temperatures outdoors
  • Half-zip neck offers additional ventilation on extra warm hikes
  • Flatlock seams prevent chafing for all day comfort when worn
  • Offset shoulder seams allow for easier wear when hauling a pack
  • Merino wool is naturally odor resistant to cut back on wash cycles
  • Item #ICE00WD

Expensive, but comfortable, fitted and lightweight

Fits well and is a lightweight body-hugging fabric, which is what I was specifically after, and is comfortable (nice soft material), though not sure how long it will last as I have bought this item before (same brand but elsewhere) and it developed a tear on the back, despite treating it with care. The cuffs and fabric overall could be more resistant to natural stretching, but this may not be possible given the nature of the fabric.

Warm, toasty, soft.

[This review was collected as part of a promotion.] This is my go-to layer for spending full days outside in northern Minnesota. Holds up well, doesn’t stink. Only wish there were more colors available in men’s sizes.

Warm but unexpectedly itchy

I found this to fit well (using the size guides I was surprised to find what size I was) though just a little snug. I also find it to be a little itchy next to my skin, which I wasn’t expecting. It’s wool, after all, so maybe I shouldn’t have been surprised but I was. When used as a base layer it performed as expected for warmth.
