Many of our flags can be used in inclement weather. Generally, when they are dry, your flags can be stored folded neatly in a cool dry place. The biggest risk during storage is snagging, tearing or ripping of the flag itself. Assuming you are careful about how you store your flag you should find them durable and capable of lasting several years. Some flags can be washed. Discuss that with the Swirling Silks sales team for details.
