I've been running around in the Starta Hoodie for about a year now.
I first got it during one of our best backcountry skiing seasons for a while. If I'm dinking around on fish scale skis, then it will usually breath well enough that I can keep it on. If I'm tossing skins on, then I will probably drop down to a tee-shirt anyways, but it is just enough insulation for heading down or when sheltered from the wind. In the winter it is also an awesome ice-climbing layer.
Once rivers start flowing in the spring, it's a great insulation layer underneath my drysuit. The hood is low enough profile that it stays out of the way, and it's got a nice cut for paddling till it's a little below freezing. If it's seriously below, I'll toss on a down jacket like the Microlight.
During the summer it will come with me for a camp jacket (and sometimes pillow) on sea and whitewater kayaking trips, and I'll bring it out sailing.
Often it will be my wander around at work jacket through most of the year.
