Christopher P.wrote a review of Arc'teryx Adahy Hooded Fleece Jacket - Men's on October 2, 2017
Familiarity: I've used it several times
Fit: True to size
Just ordered a second one.
This is a great transitional temperature jacket. It is very thin but great for cooler temps 50 to 60 (depending on your activity level of course) with some surprisingly effective thin fleece on the inside.
Also, the anti-odor treatment really works. I wish all synthetic garments had this for extended use on the trial.
I plan to use it in winter too as an extra layer right next to the base layer.
But you need to be OK with the very trim fit. If you buy your normal size it will fit over a base layer and little else. In a larger size it would be quite long on most people. So if a very trim fit does not work for you, this may not be the best choice.
It is very stretchy and mobile, and fits true to size in length but very trim in width - which works perfectly in my opinion.
