I use an my thor MX1 old moto helmet, works pretty good, doesnt waterlog, the padfing absords some but not much, and its nice all the padding clicks out and u can wash and dry it easy. The old air vents up top drain most water and it has comfortable fit, its a $300 helmet that i got for $50 new because it was one model year older. Go into a moto shop, and get a clearance thor or fox helmet, get one thats lighter and feels not as strong for dirt will be perfect strength and durability for ski. or dirt rider magazine has those cheap helmets for quads for $30 there not too bad. But id go with old moto best bang for the buck
