I have a long sleeved version of this garment and technically the garment is a 'windshirt'
http://www.outdoorgearlab.com/Wind-Brea ... -WindshirtI have used mine for multi day walks and they are a great windshell and cool weather garment for great moisture permeability. They are actually designed for aerobic activity and absorb, transfer and evaporate moisture without chilling the skin (due to the inner pile). In cool conditions they are the best midlayer I have come across. better than fleece on its own (due to the wind blocking surface), better by a squillion miles than softshell (because it is not a membrane and it is a lot lighter), it is a light garment, is warm when cold and dries quickly when wet.
I loved it on my south coast track walk (Tassy) last year because it is so versatile in squally damp conditions (you know when you have to decide 'do i stop and put on that shell or walk through the rain and see if it's setting in'). If rain sets in put on a shell, if it doesn't you stay warm and the windshirt dries quickly.
I've worn it at altitude in the tropics and it is great for staying warm in heavy cool (not cold) rain when a membrane shell is worse than useless due to high ambient temperature.
The only drawback is they lose out in versatility to a thermal/windbreaker combo or fleece windbreaker combo - which does the same thing in two separate garments. I'm surprised they aren't more popular in our conditions. I wear it skiing, walking kayaking cycling.....
