More often than not, I think many overdress.
You get hot, you sweat. You sweat you get wet, you get wet, you are DONE !
Neat little trick I learned long ago, Anti-Perspirant Deodorant on your FEET!
ARRID EXTRA DRY Cream works best for me, keeps my feet from sweating, and when you massage it in with your hands guess what, helps keep your hands from sweating also!
Polypro Turtleneck and a Fleece Neck Gator work well for neck & face protection.
I always find I am warmer when riding with others, just the company and conversation on the lift keeps your mind off of being cold.
Once you get off the lift and start riding, I've never had an issue being cold.
The bigger the SMILE & the more FUN you are having, the less chance of being cold .
