Where are people buying these helmet hoodies/balaclavas from cause they seem like they would be helpful for windy days.
I think you mean trend hood,
Lots of outerwear companies make them, just search a little more in their online store. I can tell you that they are an absolute blessing for skiing in any temps below 15.
http://www.wearleathers.com has there Good Hood going for $10 right now for Black Friday/Cyber Monday.
do you want the helmet over or under these "hoodies"?
I dunno usually people buy their ski gear from a ski shop
Anon has the MFI hood that has a magnetic face mask that will connect to any newer Anon goggle for total face protection, if you have the goggles or are looking for a new setup entirely I highly recommend. A little pricy but zero fog and really comfy.
