You'll love 'em. Apart from talking with people on the chair (when the sound was a bit subdued), I forgot I was wearing a helmet (this is my first helmet). It was warm even without a balaclava (which I have for very cold days), and the fit between the goggles and helmet is perfect (as you'd expect). I'm impressed with what Marker did with these brand new products.
I couldn't get the ESP50 lens that I wanted because of inventory, but the ESP15 is a nice lens for bright days. It was a bit difficult to see in the shadows when I transitioned from bright Colorado sun to dim shadow.
