Nylon vs Polyester American Flag: Which One Lasts Where You Live?

We hear from porch people and open-lot people, and their questions sound alike: which fabric lasts, nylon or polyester? The answer starts with where the flag hangs, so that is the first thing we ask. Where it hangs decides most of the nylon vs polyester American flag question, since a flag that looks perfect on a quiet porch bracket can come apart on an open lot. We make and ship both kinds. Neither one wins everywhere.

TL;DR: If your flag hangs on a porch or wall bracket in light to moderate wind, nylon is the pick: lighter cloth that starts flying in a light breeze. Exposed site and strong, steady wind? 2-ply spun polyester, a heavier cloth with a canvas-like feel. Not sure which one describes your yard? Tie a strip of ribbon to the bracket; we walk through the test further down.

Quick pick

• Porch or wall bracket, light to moderate wind: Durable Patriot high-grade nylon flag, sizes 2x3 to 12x18
• Open yard or exposed lot, steady strong wind: Everlast American Pride 2-ply spun polyester flag, sizes 3x5 to 6x10

Nylon vs Polyester American Flag: What You're Buying

Durable Patriot is our high-grade nylon flag, a smooth, light cloth that picks up a faint sheen when the sun hits it low. Everlast American Pride is the 2-ply flag in our lineup. The cloth is heavy-duty spun polyester, matte and canvas-like, and noticeably weightier than the slick nylon next to it. On origin there is no split: each flag is 100% made in the USA.

Lay the two on a table and you can tell them apart with your eyes shut.

Light Air and Hard Wind

In our experience, the nylon flag ripples at the slightest push of air on a still morning, while a spun polyester one hangs straight down beside it. That is simply how heavy cloth behaves: it needs steadier wind before it lifts. On a porch this works in nylon's favor, because a wall or a line of trees has usually taken the edge off the wind before it reaches the bracket, and nylon keeps flying in what is left.

Move either flag to a hilltop with steady wind behind it and the picture flips. The flag snaps all day, and the strain builds at the fly end, the free edge farthest from where the flag attaches. That corner is where a loose thread tends to show up first. Everlast is the heavier cloth, and it is the one we suggest for exposed sites.

Sun and the Pink Stripe

Whether a nylon flag fades faster than polyester depends on which page you land on, since the pages that put a number on it rarely show how they measured. Any flag in strong sun fades eventually. The red stripes tend to turn pink before anything else changes, and a flag on a south or west wall gets there sooner than one on a shaded porch, because those walls take the most sun. Side by side, nylon looks brighter and a little glossy, while spun polyester looks deeper and flatter.

On a south wall, buy two and take turns.

Rain and Wet Flags

The Flag Code says to not display a flag on days of inclement weather unless it is an all-weather flag (4 U.S.C. § 6(c)). The American Legion's flag FAQ counts nylon or other non-absorbent material as all-weather, and nylon is the only material it names. The Durable Patriot page says its colors shed water, and the Everlast page says it is designed for extreme weather. When a storm settles over the house we bring either one in anyway.

What differs is the day after. A soaked spun polyester flag hangs heavier than a soaked nylon one. We have no answer on which dries first.

Open Lots and Coastal Yards

Nothing slows the wind on an open lot, and a coastal yard is much the same: the air keeps moving all day and the flag never gets a rest. That is where we put Everlast. The sheltered backyard with a fence and a couple of maples sits at the other end, where heavy cloth sags and nylon earns its place.

A 6x10 catches much more air than a 3x5 on the same hem, so the bigger the flag, the sooner the fly end tells on you. On an exposed lot a 5x8 or 6x10 is Everlast territory. Everlast stops at 6x10, though, so for anything bigger the Durable Patriot is the size we make, and we would check its fly hem often and take it in for the worst storms.

Construction Matters More Than Fabric

A weak fly hem loses to the wind before the fabric tires, whichever material it is, and we would back a well-stitched nylon flag over a thinly stitched polyester one in the same gust. So we read the build. Durable Patriot has a quadruple-stitched fly hem and heavy-duty brass grommets, with a reinforced polyester header. Both flags have embroidered stars and sewn stripes. That puts the color in the cloth itself, with no printed layer on top to crack. Look at the same details on any flag you are considering, ours included.

Nylon vs Spun Polyester at a Glance

Which One to Buy for Your Situation

Here is how the nylon vs polyester American flag decision usually plays out for the people who write to us:

• Porch or wall bracket on a quiet street: nylon, since it flies in the air you get.
• Exposed yard or coastal property: 2-ply spun polyester.
• Bigger than 6x10: Durable Patriot, because Everlast stops there.
• Sheltered yard, some wind, lots of sun: nylon, and watch the red stripes.
• No idea: tie a strip of ribbon to the bracket and leave it for a week to see whether it streams or sags.

Run the ribbon test before you hang a flag in a new spot, since after a week the answer is usually obvious.

If you get hard fall and winter weather, keep one of each, as we would: nylon for the calm months, spun polyester for storm season, swapped on the same bracket.

Keeping Either One Going

Both flags take the same care. Hand wash in cool water with mild detergent and rinse until the water runs clear. Then let it dry all the way before it goes in a drawer, because a flag folded damp comes out smelling like a basement and sometimes spotted. We suggest running a thumb and finger along the fly end every few weeks to feel for the first loose thread, which usually shows up as a tiny curl of yarn standing off the hem near the outer corner. If you find one, mend that hem the same day, because a small fray travels. When the forecast looks ugly, the flag comes in. Eventually every flag ages out. Once one is no longer a fitting emblem for display, the Code says to destroy it in a dignified way (4 U.S.C. § 8(k)). The Legion's FAQ notes that nylon and polyester flags are difficult to dispose of by burning and can release harmful gases, so ask a licensed disposal service or your local American Legion post, since many posts hold flag disposal ceremonies.

Which Flag to Order

Durable Patriot is our embroidered nylon flag with sewn stripes and brass grommets, in sizes from 2x3 to 12x18. Everlast American Pride is the 2-ply spun polyester one, in sizes from 3x5 to 6x10. If you would rather browse by material, we have nylon flags and spun polyester flags, and every flag in both is 100% made in the USA.

Common Nylon vs Polyester Flag Questions

Which lasts longer: nylon or spun polyester?

We can't document a lifespan number for either fabric, so we won't invent one. In strong, steady wind we point people to the heavier 2-ply spun polyester. In light to moderate wind either one can last, and there the stitching and upkeep matter more than the cloth. Mend a loose thread early.

Is nylon or polyester better for outdoor flags in high wind?

For strong wind on exposed sites we suggest 2-ply spun polyester, our Everlast American Pride, which is heavier than our Durable Patriot nylon. Anyone hunting for the best flag material for high wind can start there. Check the fly end every few weeks whichever fabric you pick.

Can a nylon flag fly in rain?

Yes. The American Legion's FAQ names nylon as an all-weather material, and the Flag Code allows an all-weather flag in inclement weather (4 U.S.C. § 6(c)). The Durable Patriot page says its colors shed water. We still bring ours in when a storm sits on top of the house.

Is spun polyester too heavy for a house bracket?

Spun polyester is the heavier flag and gets heavier still when it is wet, so check your bracket before you order one. If the bracket is small or looks light, the nylon Durable Patriot is the easier fit. With either flag, drive the screws in firmly and check them now and then.

Which looks more traditional: nylon or spun polyester?

Spun polyester, in our view, because the matte, canvas-like finish looks closer to old-fashioned flag cloth. Nylon is the brighter of the two, with a slight sheen that catches the eye first in direct sun, and it ripples livelier in a breeze.

Does a nylon flag fade faster than polyester?

Any flag in strong sun fades over time, and the red stripes tend to show it first. Online advice varies on which fabric goes first. A shaded mount slows it down, and so does a spare flag you rotate in, which matters most on a south or west wall.

Is an embroidered flag better than a printed one?

For a flag that lives outside, we think so. Durable Patriot and Everlast American Pride both have embroidered stars and sewn stripes, so the color is in the cloth and there is no printed layer to crack or wash out. Our guide to choosing a durable embroidered American flag goes through the stitching in detail.
