I have used the stormtrackers out around town, and also out hiking in old, windy conditions. I found them to be be comfortable. As a person with chronically cold hands, they did a good job of regulating my hand temperature while active, and kept my hands pretty comfortable. I'm looking forward to using them for ski touring. Only thing I'm confused about: I thought the "sensor" part meant they worked with smartphones? This does not seem to be the case (I don't really care about this, just an observation). Although my hands met the measurements for the medium, I found the MD's too tight around the base of the fingers and thought they'd limit my circulation. I sized up to the large and have found them to be perfect. They broke in and stretched just a bit, and have a perfect fit. Maybe I just have super muscle bound fingers?
