I've got about 10 helmets for riding.
For around the house and riding ATV's (nothing radical), I really like the Zeus flip-up snowmobile helmet.
It's like a full face with the chin guard and flip down lens but there's a latch under the chin and the whole chin piece and lens pivot up so it's now like an open-face helmet.
With all the combinations of venting and stuff, I never have a problem with fogging.
It's also easier to talk, have a beverage... without taking the helmet off (which gets real cold putting back on).
I think you can get them for around $90 - $120 depending on model. HJC and others make them but even the people that sold me the Zeus didn't recommend since they're $350+ and they couldn't find anything "that much better" to justify the price for general usage.
On snowy days, I put on the Arctic Cat balaclava that goes over the head but is thin on the area that the helmet covers. Great head and neck protection.
