Connor Johnsonwrote a review of Bjorn Daehlie Zone Half-Zip Top - Men's on December 14, 2017
Familiarity: I've used it several times
Fit: True to size
I got some Bjorn Daehlie gear for winter training and activites in Salt Lake City, including these. I spend my time running and road riding to cross train as well as backcountry skiing. I'm 5'11" and 175lbs and got the L/XL. I likely should have gone with the M/L but this is a pretty great base layer. Its a bit long and long sleeves, but like that for being able to curl up my hands in if its a cold day and without gloves.
I would say that the material is soft, but still durable enough that it seems like it will hold up to at least a few seasons of training and skiing. I do like the quarter zip though, its an easy way to dump heat and regulate those temps. These will be a go to for me for cold weather activities this year.
I would absolutely recommend this to someone looking for a good midweight base layer. I've also mountain biked with it as a base layer in 25 degree weather and it did great with an outer shell. I plan on using it for touring in the backcountry as soon as we get more snow!
