Good:
- comfortable
- warm (I don't wear it above freezing)
- magnetic buckle is great
- unique styling which pairs well with fatties
- can wear skiing/boarding as well
- much, much lighter than it looks
Bad:
- difficult to hear cars with ear pads so not the best for commuting (but earpads are removable)
Sizing:
- runs a bit large. Buy it the same size that you wear in a road helmet if you will wear a skullcap with it. With no skullcap it is about 1/2 size bigger than road helmet.
