Snow is serious biness, Right now, I'm enjoying the balls cold weather while many do not, But this really helps to maintain a pack when you get the ground to freeze up before getting the snow to insulate.
Some of the short range models are starting to tick a bit colder for tonight and tomorrow, Hope they are getting a clue in the coastal plain up here, I would like to believe the reggie but i don't.
I rode in -20 to-35 conditions up in the county several years back on back to back days, Once its that cold, You can't tell the difference from -20 to -35.
