I read that a standard sleeping bag loses most of its heat through the ground, not the air
I was looking at a review for a new sleeping pad on OutdoorGearLab last night, and they said something like 75% of heat loss when you're sleeping outside happens through conduction into the ground. I always thought the bag itself was the main thing keeping me warm. It totally makes sense now why I was so cold that one night in Yosemite, even with my 20-degree bag. I was just on a thin foam pad. Has anyone else had a trip totally turned around by upgrading their sleeping pad first?

That 75% figure from OutdoorGearLab is a real eye opener. My first few backpacking trips were miserable until I swapped my old foam pad for an insulated air one. The difference in sleep quality was honestly shocking.

Yeah, it's wild how much we focus on the bag and tent but skip the ground. That foam pad was fine for a kid in the backyard, but real cold ground just sucks the heat right out of you. I spent years thinking I just slept badly outside, turns out I was just cold. Getting a good pad changed everything, it's like the secret to actually wanting to go out again.

Took me way too long to figure out I wasn't just bad at sleeping on the ground, I was just freezing. That old blue foam pad should come with a warning label.
