I have had this outdoor rug on our lanai in Naples FL since April. This has been one of the wettest rainy seasons on record and yet this rug has held up against moisture. It often gets a little rain on it when we forget to lower the lanai storm shade but so far it is mildew free. The design is tropical yet contemporary. The colors are neutral and go well with my more colorful lanai furniture. It's a good bargain. Thanks Overstock!
