Everyone else camping in the same tent are walking around like they slept with a tree root poking through their ultralight pads, but you didn't really have that problem. Ultralight pads might be great for backpacking, but when the car is right next to the tent, you prefer having a little more cush under the tush, which is where Sea to Summit's Comfort Deluxe SI Sleeping Pad comes into play. Delta Core technology applies four inches of luxurious foam in specific areas for a supremely comfortable night's sleep, and the convenient self-inflating design means you can save your breath for the campfire when you're getting camp set up.
