What to Pack for a Winter Day Hike

Summer hikers pack for the trip they planned. Winter hikers pack for the trip they might accidentally get.

A short route in the cold is a different animal from the same route in July. Your margin for mistakes shrinks. A twisted ankle that is an annoying limp in June becomes a very long, very cold wait in January. So here is the list we actually use for a winter day hike in the hills. Adjust for your route, and if it involves avalanche terrain, this list is not enough. Take a course and go with someone who knows.

On your body

Wicking base layer, top and bottom. Cotton stays home.
Insulating mid layer you can vent, like fleece.
Shell jacket and shell pants that block wind.
Wool socks, and a spare pair in the pack.
Boots that fit with those socks on. Test this at home, not in the parking lot.
Microspikes or traction for ice. They weigh almost nothing and save the day often.

In the pack

A puffy jacket you never wear while moving. It is for stops and emergencies.
Second pair of gloves and a warm hat. Lost gloves ruin hikes.
Headlamp with fresh batteries, plus a spare. Winter days end early.
Map and compass or a phone app with offline maps. Keep the phone warm in an inner pocket, because cold kills batteries.
Insulated bottle or a thermos. Hoses freeze.
More food than you think. You burn more in the cold.
First aid kit, emergency blanket, lighter, whistle.
A sit pad. Sitting on snow steals heat fast, and this is the item everyone forgets.

What stays in the truck

The fourth layer. The big camera. The extra pair of boots. The dry clothes and a thermos of something hot do stay in the truck, on purpose, because the drive home is the best part of a winter hike.

Three rules that matter more than gear

Leave your plan with someone, including your turnaround time.
Set that turnaround time before you start and keep it. The mountain will be there next week.
Start early. Daylight is your most limited supply.

That is the list. We also keep a Base Camp notebook in the pack for trip plans and bad jokes. For the warm-up afterward, you may want the right hoodie waiting in the truck.
