Craig Lwrote a review of Outdoor Research Alpine Onset Hooded Top - Men's on October 12, 2018
Familiarity: I've put it through the wringer
Fit: True to size
I love this layer. It's the best layer. The best. For one, if you're talking about the best layering for winter, you are pretty much exclusively talking about Merino. It feels nice on the skin, resists odors and "the funk" in a way you cannot believe until you try it, and it wicks moisture and regulates temps.
Besides that, this layer is the peeerfect blend of fit and function. I am 6'5 and 210lbs, and went with the XL. The fit is trim, perfect for layering over, but not so tight that I look like a sausage when just wearing this piece around town / office / whatever. The length is slightlyyy long, again, just perfect so that you can tuck it in while layering, but it still looks good for the around town / office wear. The hood is a great touch to the piece as well, if you are looking for one without a hood, you are in luck that exists as well. When I go out and combine a bit of wind with cold air (think skiing, bike commuting in the winter) my ears freeze, and give me a big headache. Not sure if that's just me, but for me it makes a hood or something like it essential
Lastly the material is a nice, relatively thin blend which combined with the 1/4 zip makes it FANtastic for ventilation. I am the kind of guy who has a really hard time being comfortable and not overheating when doing aerobic activities in the cold. This thing base layer keeps my skin covered, but doesn't trap too much heat. Once I feel myself getting too hot, I crank down the zipper and all the heat from my chest / torso zaps right out.
I think this piece is the perfect layer for snowshoeing, winter bike commuting, and any other aerobic activity for those that tend to run warm, and want their base layer to be light and breathable.
100/10 would buy again, and probably will if and when I wear it to pieces.
