Several nights in a tent may have bad consequences. Sleeping on hard and cold ground is simply not for everyone.
If you want to camp out and wake up refreshed without back pain and fever, you need both a tent and an inflatable sleeping pad LOAP. It insulates you well from the cold ground, so you will stay warm even, when the night gets colder.
Your sleep will not be disturbed by stones and other unevenness, which you normally feel on every movement while sleeping on a classic sleeping pad.
You fill also find classic rolling pads in the collection of LOAP sleeping pads. They are best suited as exercise mats for yoga, but you'll appreciate them even on a beach.
