Good ultralight sleeping pad
Excellent cheap pad when backpacking. When weight and money are a factor, this are sufficient for sleeping pads when backpacking. The green ones are the old version and have held up well for a number of years. They have been used during well below freezing nights (20 - 25F) and have insulated my body from the ground well and kept me warm. They take a beating strapped to the outside of our packs but they are still going strong.
They arent the most comfortable pads but they work fine. If you are a car camper and weight isnt an issue, look somewhere else, but if you need something lightweight and provide insulation from the cold ground these work well.
