A triple threat.

The Icebreaker Men's Descender Half-Zip Top delivers the next-to-skin warmth you want when you're hamming it up at the ski resort or getting serious on the trail. Its medium weight merino wool material is suitable for high-aerobic activities on really cold days thanks to merino wool's natural ability to manage moisture, temperature, and odors. The striped fleece fabric even traps air for increased warmth, and it has a deep zip neck for quick ventilation.

A Great Alpine Layer

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

The Icebreaker Descender Half-Zip Top has actually been my go to base layer for resort and backcountry skiing for the last season and it has fit well into my repertoire. I actually run a bit warm so this warm weave does well for me as I actually forgo a mid- layer in lieu of this base layer as it keep me warm enough while vented during the cold days while mostly keeping me cool during the warmer days with venting.
The piece runs a bit big and is slightly heavy but well worth the misgivings.

I'm in love!

I was a bit nervous at the cost, but I am totally sold and in love. The fit worked well for me (it was a tad bit long, but I'm a tad bit short). It wasn't itchy at all and I didn't have any issues with smell after I was done for the day. After washing it, I didn't see any evidence of wear. This is a winner!

Great Jacket

I might be wearing this every day this winter. The merino fleece interior is soft and breathable and can be worn for nearly a week without getting dirty. The fit is slim and looks great.
