Besides handling a beating from getting hit in the head or thrown off my bike in polo, this helmet is so super light and comfy that I pretty much forget I am wearing it. In the summer it is surprisingly cool and in the winter it's nice and warm with the optional winter liner.
I bought these at the end of last year as my first pair of clipless and I love them. I am a delivery bicyclist, so I am wearing these for about 4 to 6 hours a day.
I can't attest to how they fare running around in the woods, but I can say that they handle running across pavement and up stairs with a heavy load on my back pretty well!
Nice and light and it's easy to tighten down the straps to get a perfect fit. They also vent really nicely, even in 95+ degree weather on black asphalt.
Does this jacket have a hood?
The specs say no, but the photos make it seem like it does.
