Norriswrote a review of Icebreaker Quantum Hooded Full-Zip Shirt - Men's on February 13, 2017
Familiarity: I've used it once or twice and have initial impressions
Fit: True to size
All the five star rave reviews (12 at the time of my purchase) might give one the impression that there is no room for improvement, but that is not the case. There are a few flaws worth mentioning. First and foremost, the full-length front zipper is a left-handed one, meaning that the pull tab to zip it up is on the left side from the point-of-view of the wearer and so you have to use your right hand to fit the insertion pin into the box of the zipper and your left hand to pull the tab of the zipper up. This is precisely backwards from every other full-length zippered fleece top or jacket I own, and is annoying for a right-handed person. Second, the gauge of the front zipper is too large in my opinion. The width and thickness of the fabric (or "tape" as it is known) that the zipper is embedded combined with the size of the zipper and the way the zipper is sewn into the garment and backed with more wool fabric makes the whole length of the front zip of the hoody feel too thick and stiff, especially considering the relatively thin wool fabric of the rest of the garment. The plastic reinforced top and bottom of the zipper tape contributes to this also. The ends of the sleeves are a little different, there is a separate end piece sewn on to each arm, which is the part which includes the (enormous) thumb holes. These don't look too attractive in everyday wear, but you can tuck these arm extensions in and under after putting the garment on. Finally, the hood is cut in such a way that it covers quite a bit less of the sides of ones face at the jaw line than other hoods, although some might like this. All in all I must say I was a bit disappointed given the very high price and the expectations created by all the gushing in the other reviews. I'm pretty tall (6' 5") and wish it were just a tad longer, but other than that the L size gives me a nice athletic fit. I can't be sure but I think the XL would have been a bit baggy.
