Staying Warm on the Slopes

I've tried to convince a few people 'round these parts to give skiing a try and a lot of refuse to brave the conditions.  It takes 20-30 minutes to break a sweat and shed the winter chill but I think it's worth it.

I picked up a couple rechargeable hand warmers.  Some keep a charge for more than an hour.  Others are complete duds.  

I also dress in layers.  A full head of hair increases body temperature by 5-10 degrees IMO.  

I'm open to other ideas that will help me convince friends and family to join me in the greater outdoors during the wintertime.
