Yeah, you might have a sleeping bag but even with that you are still laying on the hard, rocky ground. Something you will pay for in the morning with a stiff neck or back, and that doesn’t help you if you have a full day of hiking ahead of you. That’s why you need a sleeping pad and not just any sleeping pad but a self-inflating sleeping pad! Inside are rapid rising foam cells that easily let air in. There is also a valve for if you like it extra airy. It even has a built in pillow! Roll it up and strap it tight into an easy to carry pouch when you are finished. You’ll need one of these for your next weekend getaway!
