Choosing the right flag material ensures your American flag looks great and lasts longer, whether you’re displaying it at a home, business, or school in Michigan. At Flags Unlimited in Grand Rapids, MI, we offer both nylon and heavy-duty polyester (also known as poly-extra) flags to suit different environments. Here’s a quick guide to help you decide which material is best for your flagpole, plus how our lighting solutions can keep your flag flying proudly.  

1. WIND TOLERANCE

Polyester (Poly-Extra): Designed for high-wind areas like lakefronts, hilltops, or open fields, polyester flags can withstand winds of 30-50 mph. Their heavier construction ensures durability in harsh conditions, but in low-wind areas (under 15 mph), they may hang limp, reducing visibility.  

Nylon: Ideal for moderate-wind areas like neighborhoods, valleys, or urban settings with tall buildings, nylon flags handle winds up to 20-30 mph. Their lighter weight allows them to catch even gentle breezes, ensuring your flag stays visible in calmer conditions.

2. WEIGHT

Polyester (Poly-Extra): This heavier material is more durable in Michigan’s harsh winters, resisting fraying in cold, windy conditions. However, it absorbs more water and may not fly well when wet, making it less ideal for rainy climates unless paired with proper flagpole lighting to maintain visibility at night.  

Nylon: A lighter, moisture-wicking material, nylon flies well even in wet weather, making it a great choice for Michigan’s rainy seasons. However, it’s more prone to sun-fading over time and may tear more easily in extreme winter winds.

3. CONSTRUCTION

Both nylon and polyester flags are made with sturdy, outdoor-ready threads and a durable weave to withstand the elements. Polyester flags often feature a tighter, 2-ply weave for added strength in high-wind areas, while nylon’s looser weave enhances its “flyability”—how well it moves in the breeze. Neither material is inherently better; the choice depends on your environment. At Flags Unlimited, we ensure both options are built to last, whether you’re flying a flag in a quiet Grand Rapids neighborhood or a windy lakeside property.  

4. FOLLOW CODE

No matter which material you choose, the U.S. Flag Code requires your flag to be illuminated at night if flown after sunset. Explore Flags Unlimited’s solar and hardwired flagpole lighting options to keep your flag visible and compliant, especially during the Midwest's long winter nights.
