Have not used yet
It's big enough to use everything from a picnic to an insulated ground cloth with an Arturus reflector blanket. However, my reason for 3 stars is the first time I tried testing a strap-loop on this blanket it nearly pulled out with just a slight tug - possibly 5 pounds worth of pull. Crazy weak stitching here. I would recommend that Arcturus improve the stitching at these tie points and also offer a model bonded to a reflector blanket.
Seems to be quality made camping pad and got at good price and good quality all I want and need
