Bull - I did a little research on the company (Valley Forge) and this is what I found:
Q: Why are flags made out of different materials?
A: Many people use flags for a variety of different purposes. Some flags are used for outdoor display, others for memorial purposes, and still others for indoor display. Depending on its use a flag can be made out of nylon, cotton, polycotton, polyester, or two-ply spun polyester. Common uses for these flags might be:
Nylon - Perma-NylTM is the most durable and serviceable option. Nylon retains color well, flies nicely in a light breeze, dries well, and is easily cleaned.
Cotton - BestTM is a traditional, and too many the most beautiful, material. This fabric has a natural feel. However, like anything made of cotton, it is less durable and should be used for decorative or ceremonial purposes.
Polycotton blend or polyester - these materials are economical yet attractive. They are excellent for temporary use or where cost is an issue.
Two-ply spun polyester - Koralex IITM is a premium material that holds up well in windy or harsh conditions. Because it is spun, it has the feel of cotton, but its synthetic nature gives it the durability of nylon.
Remember to always treat a flag with common sense and respect. Never fold it when wet, regardless of material, and replace it whenever it reaches a condition not befitting the symbol of the country. A good rule is that if you wouldn't wear it don't fly it.
Q: What are some general flag care suggestions?
A: Fly Ends: Watch for the first signs of fraying. Flags can be trimmed and re-hemmed greatly prolonging the life of the flag.
Windy Days: High winds are extremely rough on flags. If at all possible, take down the flag when winds exceed 30 mph.
Rain or Snow: For best results, do not expose your flag to these elements. If exposed, after a heavy rain or snowstorm take down the flag and spread it out to dry. Do not fold or roll up a wet flag.
Air Pollution: To minimize the effects of dirt, air, smoke, car emissions, etc. keep the flag clean. Having two flags and interchanging them is highly recommended to prolong the life of a flag.
Q: What is the expected life of a flag?
A:Our U.S. Government customers have told us that they generally expect an outdoor flag to last approximately 90 days when flown from dusk until dawn in good weather. Sensible care may result in a flag that lasts longer and looks better over time.
The Valley Forge website prices this flag at $79.**. I hope you feel like I'm not looking to make money off this deal. I'd just rather it went to somebody who can/will display it.
