Bill C.wrote a review of Icebreaker RealFleece 260 Sierra Full-Zip Jacket - Men's on October 20, 2012
Familiarity: I've used it several times
Only improvement, would be a stowable wool hood, but I'm sure there's a model that has that.
Use it hiking, walking, biking, even all day at work over my oxford shirt (new office is too cold). Love, love everything from icebreaker. It was a revelation wearing a thin wool Icebreakers shirt for a week in southern Utah on Coyote Gulch scout hike/camp (during the hottest part of August). Still smelled passable after an entire week. Expect nothing less of this jacket. The large inner chest pockets were a pleasant surprise, on top of the two outer side pockets and left shoulder pocket. A bit odd that it zips up on the left like a lady's shirt though.
