Purpose-built to help you sleep easy even when it's cold or freezing outside, insulated sleeping bags from The North Face keep you warm and comfy in cold-weather climates.

For casual spring and fall camping, choose lightweight rectangular sleeping bags with 40-degree or 20-degree insulation ratings. Designed with synthetic Heatseeker™ Eco insulation to keep you toasty and dry, these sleeping bags are lightweight and easy to fold for convenient transport to the camp site. Our insulated rectangular designs offer the same amount of sleep space as a twin-size mattress – zip two together for a king-size sleeping experience you can't get anywhere else.
