This thing is ridiculously warm. Not kind of warm, like outrageously warm. If you live somewhere where it gets cold as balls, consider this jacket. I can only wear it when it's below 10 degrees, even with just one tech tee underneath. Super waterproof as well. The only reason I gave it 4 stars is one of the snaps on the front flap popped off the first day I ever wore it. Not that big a deal, but a bit of a bummer for a brand-new jacket. Other than that, I love it - fits nice and long and keeps me warm during night riding or really cold days.
