If I buy a ProLite mattress, will it be warm enough on the snow?
No. The ProLite mattress is recommended for three-season use. Some people sleep colder than others, and many snow camping pros prefer to sleep with a Ridge Rest® or Z Lite™ under their self-inflating mattress for increased warmth. If you sleep particularly cold, we recommend the combination of a closed-cell and self-inflating mattress for extra protection. See Pro Tips for more snow camping ideas.
