Winter camping in the lower 48 — Sierra in February, Rockies in January, even the Smokies in December — is the hardest version of outdoor travel. Cold kills faster than heat. Wet cold kills faster than dry cold. The margin for gear failure is small. Here's the pack list for 2-3 days of shoulder-season or true winter camping.
Shelter — 4-season required
- 4-season tent with steeper walls and more pole structure than a 3-season. Designed to shed snow load and handle wind.
- Snow stakes (T-stakes that hold in compacted snow — regular stakes don't work)
- Tent footprint or polycro
- Snow saw or shovel for leveling a platform
Sleep system, doubled-up
- Sleeping bag rated 0°F or colder for true winter (10° colder than the worst expected night)
- Two sleeping pads — one closed-cell foam, one inflatable, stacked. Total R-value 6+.
- Liner adds 10°F to your bag
- Vapor barrier liner if it'll be below 0°F (keeps your sweat from soaking the down/synthetic fill)
- Sleep with tomorrow's water bottle inside the bag (won't freeze) and tomorrow's clothes (warm dressing in the morning)
Layers — many of them
Winter requires more layers than any other season:
- Merino wool base layer (top + bottom)
- Mid-weight fleece
- Light synthetic puffy
- Heavy expedition down or synthetic puffy (camp wear)
- Hard-shell jacket and pants
- Two pairs of gloves: light liners + heavy mittens (mittens are warmer than gloves)
- Two beanies (one slept in, one for daytime — hat-induced sweat freezes)
- Buff or balaclava for face cover
Footwear — the snow problem
- Insulated waterproof boots (Sorels for stationary cold, mountaineering boots for moving)
- Gaiters (knee-high)
- Two pairs of merino wool socks per day; rotate sweaty pairs out
- Snowshoes or skis depending on terrain and snow depth
- Microspikes or full crampons for ice
Hydration — keeping water from freezing
- Insulated water bottle (Hydroflask or Yeti) — bladders freeze at the hose
- Sleep with bottle in your sleeping bag
- Pot for melting snow (a major time sink — count on 1-2 hours of snow-melting per day for water)
- Skip the filter — most filters freeze and break. Boil instead.
Cook system
- Liquid-fuel stove (white gas) — canisters lose pressure in cold, often won't work below 20°F
- Lots of fuel (snow-melting + cooking + hot drinks = double summer fuel needs)
- Insulated mug with lid
- High-calorie foods that don't freeze: hard cheese, sausage, nuts, candy bars, dehydrated meals
Safety — winter-specific
- Avalanche gear if in avalanche terrain: beacon, probe, shovel, plus the training to use them
- Trekking poles for stability on snow
- Heavy-duty headlamp with cold-rated batteries (lithium, not alkaline)
- Hand and foot warmers (chemical heat packs)
- Personal locator beacon
- First-aid kit emphasizing frostbite and hypothermia
In winter, comfort is safety. A camper who is shivering is a camper who is making bad decisions.
Practice before commitment
Don't make your first winter trip a full multi-day expedition. Start with a winter day-hike, then a single overnight at a developed campground in the snow, then a real backcountry trip. Skills compound; mistakes compound faster.
