Fleece or midlayer
The layer you'll wear more than any other.
Warm hat (beanie)
Lows drop to 21°F and wind hits 15 km/h, so exposed skin on your head loses heat fast.
Gloves
At 21°F, bare hands go numb within minutes on the trail.
Insulated winter boots
Snow covers the ground and 21°F lows freeze regular boots solid.
Polarized sunglasses
High altitude and snow reflection bounce UV rays onto your eyes even at low index.
DEET or picaridin repellent
December has only 4 rain days, so insects are dormant and this stays home.
