Review on Ultrathick All-Weather Foam Sleeping Pad With Pillow For Backpacking, Traveling, And Hiking - Fast Air Self-Inflating Insulated Mattress - Durable Camping Mat In Green (3 Inches) by Stoner Fulton

I actually purchased this, using money. I used this to sleep in the back of my car for three consecutive nights and I can say that it worked quite well! A few things:- You've got to really give it the business when you go to roll it back up and stick it in the bag. I didn't quite have the mustard when I went to put it away and ended up tearing the seam of the included drawstring bag :( When I got home I re-rolled it and it slid in effortlessly- Quality seems to be decent. The material is comfortable on the skin and seems to be durable, we'll see how it holds up with more uses- Plenty large. I'm 6' 2" and under 170 lbs. The thing provides enough sleeping surface, though It would be cool to have something that fit the entire width of the back of my car instead. no such option exists to my knowledge- I ended up sticking my mouth over one of the knobs and gave it one last puff of air to help inflate it. Seems to have maintained its inflation through the night- Includes a patch kit and one replacement plastic valve knobI'm satisfied with it. How this thing holds up over various uses will determine whether its a good value. Sleeping in a car has other factors to consider aside from the surface you sleep on - make sure the car is parked somewhere level and try 'n keep the bugs out! The first night was a very unpleasant learning experience. but that's in no way the fault of this product.
