I have a Bern Macon as well, with the visor insert for warm weather and the knit insert for the winter. I wear glasses, and I really like the short visor; I wish I had bought the Watts so I had the visor with the winter knit.
It is heavy compared to traditional road bike helmets, but I only have a short 4 mile commute, and I find mine to be super comfy. I've been wearing it in the 90 F Boston summer, and it's warm, but not intolerably so.
It really shines in the winter; the knit is comfortable down to about 5 F for me.
