I love the beachy colors of this rug.  I used this outdoors by our hot tub and patio area.  It is not heavy enough to stay down on a windy day, unless you have furniture on top of it to keep it down.  It is pretty heavy material (as you would expect from a rug) but it would have to be cleaned professionally (not sure how).  I guess this is the one downfall of having an area rug outside in the elements.  I give it a 4 because of the colors but functionally for an outdoor rug I give it maybe a 3.
