Cold-weather camping & RV kit for Banff National Park

Nights here drop near or below freezing even inside the recommended season — usually because of altitude, not latitude. The gear that matters is what keeps heat in overnight and water lines flowing.

0°F sleeping bag
A 30°F bag is the single most common mistake at altitude. Rated to 0°F leaves headroom.
View ↗
Insulated pad, R-value 6.5
Most heat is lost downward. R-value above 5 is the line between a cold night and a warm one.
View ↗
Portable propane heater
9,000 BTU with oxygen depletion sensor — the standard for tents and small RV interiors.
View ↗
Reflective window insulation
RV windows are the biggest heat leak. A roll cut to size costs less than one cold night.
View ↗
Heated drinking-water hose
Below freezing an ordinary hose splits. This one is thermostat-controlled and drinking-water safe.
