Smartwool's warmest classic base layer with a hood and a half zip, so you can dump heat on the bootpack and zip it back up for the ride down.
Merino keeps you warm when it's damp and doesn't stink after a weekend of laps. The hood adds a layer under your helmet on the coldest days.
Cold mornings on Peak 10 and hikes out to the bowls when you need warmth that breathes.
