What works tonight

The gear this night calls for, for someone who sleeps like you.

  • You have this

    Sleeping bag

    Comfort 65°F or colder

    Usually sold as a 56° bag. The number in a bag's name is the limit, not the comfort.

  • You have this

    Underneath you

    R1 or more

    The R-value says how well a pad keeps the cold ground out.

Before you sleep

  • Stake out every guyline and point the low, narrow end of the tent into the wind.
  • Rain is possible from about 10 p.m. Keep the rain fly on and bring shoes and packs inside.
  • Bring shoes, clothes and electronics inside. Anything left out will be wet by morning.
  • Open the tent vents and keep the door zip open a bit at the top. Some condensation inside is normal on a night like this, so bring a small towel to wipe it off.

Assumptions

  • Bag categories use typical ratings as sold: summer about 50 °F (10 °C), 3-season about 30 °F (-1 °C), winter about 15 °F (-9 °C). The number in a bag's name is usually its lower limit, so its comfort rating is about 9 °F (5 °C) warmer.
  • What you lie on: foam mat about R2, thin air pad about R1.5, insulated pad about R3.5, winter pad R5 and up, van bed about R4, air mattress about R0.5. Colder ground needs a higher R-value.
  • Shelters hold a few degrees early in the night and less towards morning. Wind and clear, calm skies take warmth away.
  • Weather: Open-Meteo forecast for your spot, on a grid of a few kilometers, corrected to its height.
  • These are rules of thumb, not measurements. People and gear vary.

A forecast, not a promise. Mountains, valleys and water make their own weather, so trust what you see and feel on site. Terms and liability

Checked for a double-wall tent, a 3-season bag and a thin air pad. Check your own gear here.
