Frequently Asked Questions

What's the difference between comfort and limit ratings?

Comfort rating is the temperature at which a cold sleeper will sleep comfortably. Limit rating is where a warm sleeper might feel cold. Always choose the comfort rating for a good night's sleep.

How does a sleeping pad affect warmth?

Your body compresses the sleeping bag underneath you, losing heat to the ground. A pad with R-value 4+ adds significant insulation. In winter, use R-5 to R-8 pads.
